Gemtech ONE Suppressor

The Gemtech ONE is still fairly compact for a rifle suppressor.

The new rage products in the suppressor market are multi-purpose silencers. Some models like the SilencerCo Hybrid and Griffin Armament Optimus are made to cover both rifles and pistols. Others, like the Gemtech ONE, are multi-purpose, but for rifles only.
I like this more narrowed approach. Certainly multi-caliber rifle and pistol silencers are a great way to cover most of your gun collection with just one $200 tax stamp to Uncle Spendy, but there are tradeoffs. If a suppressor is to handle rifle pressures for the big calibers, it’s going to be somewhat overbuilt for pistol use. That’s not a big deal; it’ll just be larger and heavier than you need.
If you’re open to the idea of paying Uncle Spendy twice for a total of $400, you can get a .45 caliber pistol suppressor that can also work on any smaller caliber and a rifle suppressor that can cover everything from rimfire to 300 Magnum. This is the scenario where the Gemtech ONE shines. It’s designed for rifle use, and while it will be oversized for smaller rifles like rimfires, that’s not as big of a deal when mounting on a six to 12-pound rifle as when trying to stick it on a two-pound pistol.

I also used the ONE on this .22 – a Smith & Wesson M&P15-22 Performance Center rifle.

About the ONE

I can’t even say “the ONE” without suffering from “The Matrix” flashbacks. I guess that’s OK, I kinda liked the first one. Regardless, as we’ve touched on already, the “one” part of the ONE refers to one suppressor that fits a whole boat load of rifle calibers. How many? Everything from .17 HM2 to 300 Winchester Short Magnum and everything in between. I’ll post the full list from Gemtech at the bottom of this article, so you don’t have to scroll through that just yet.
There are two ways to mount the ONE to your rifle: a direct thread mount and a quick attach that pops onto a compatible Gemtech muzzle device. My trial unit from the good folks at Silencer Shop came with two different flash hiders – one for .30 caliber and the other for .223. These are threaded at ⅝”x24 and ½”x28 respectively.

The Gemtech flash hider – well used a you can see from this photo!

Just to be clear, the ONE ships with the Bi-Lock Mount and a 5/8×24 Direct Thread mount, but the muzzle device itself is not included, so you have to add one or more of those to your order if you want quick attach and detach functionality. If you have questions, the Silencer Shop folks can help you out.

The Mount

Direct thread mounts are simple, but if you want to get the most out of a suppressor designed for multiple calibers, you’ll want to use the Bi-Lock Mount system. Compatible muzzle devices have two lugs of different sizes on opposite sides of the muzzle device. Why different sizes? That’s so the silencer will only mount one way. By mounting exactly the same every time, the point of impact won’t change when you remove the ONE and re-add it later. If you put a compatible muzzle device on each rifle you want to use with the ONE, you can zero each one and freely move the suppressor back and forth without losing your zero on each particular rifle.

The muzzle devices have lugs to orient and hold the suppressor in place.

The mount is simple to use. Slide the suppressor over the lugs and push against the internal spring. When the spring is compressed a bit, rotate the suppressor body and let go. That’s it. To remove, push the suppressor towards the receiver and rotate in the opposite direction and it will slide right off. I like the mounting system and found that’s it’s not prone to sticking like other designs when the silencer gets hot, dirty and nasty. I also did not detect any point of impact shift when moving the suppressor between rifles and back again.
The bottom line is this. Bite the bullet and buy a muzzle device for each rifle you want to use with the ONE. It’s well worth it.

The suppressor will only mount one way as the lugs are different sizes.

Shooting the ONE

Since the ONE goes all the way down to tiny rimfire territory, I decided to try it on a .22LR rifle. Because fun. I did have a SilencerCo Sparrow-22 on hand, so I could switch back and forth on the same gun to see what performance differences I might uncover.
I mounted the ONE on a Smith & Wesson M&P15-22 Performance Center rifle. This .22LR plinker comes with standard ½”-28 thread per inch threading, so the 5.56mm flash hider was ready to mount with no adaptors required. While the ONE is oversized to muffle the tiny little rimfire, it worked like a champ. It even made my Smith & Wesson M&P15-22 look just like a big boy rifle!

The ONE is compact. It’s shown here next to a SilencerCo Specwar 7.62.

I shot a wide variety of both super and subsonic .22LR ammo through this setup. Of course with supersonic varieties, I still heard the “crack” of the miniature sonic boom, but the muzzle blast was dampened. The subsonic .22LR loads like the new CCI Suppressor ammo were amazingly quiet. I mean the loudest noise was the operation of the bolt. I’m not sure, but going by the smiles of my range neighbors, this combo might have generated anti-noise, which means ambient sound was sucked away from the universe and relocated to that second obelisk from 2001 A Space Odyssey.
I clocked the CCI Suppressor ammo from this configuration using a Shooting Chrony and found average muzzle velocity to be 973.2 feet per second – well below the speed of sound. Got rodents? Got neighbors? This combination is your winning ticket.
Keeping the 5.56mm muzzle device on that rifle, I installed the 7.62mm flash hider and mount on a Daniel Defense DDM4v5 300 Blackout rifle as I wanted to check this silencer out with both supersonic and subsonic ammo. Using the Bi-Lock Mount system also allowed me to move the silencer back and forth between the two rifles in seconds.

The end cap is fixed with a hole sized for .30 caliber.

From the 300 Blackout, I used both supersonic and subsonic ammunition. The subsonic variety was from American Eagle. Their new Suppressor line uses 220-grain bullets and from this rifle, with the suppressor attached, velocity measured with my Shooting Chrony was just below the speed of sound. The noise was a pleasant “whoosh” followed by a satisfying “thud” when the fat and slow bullet hit the dirt berm 100 yards down range. This part of the trial was kinda fun – my range neighbors got a kick out of the thud too.
I also checked out the Gemtech ONE using supersonic 300 Blackout ammo, in this case, a 125-grain Nosler Ballistic tip hand load moving at just under 2,000 feet per second. The muzzle blast was virtually non-existent, but of course, I heard the crack generated by the small sonic boom.

Point of Impact Shift

I tested the Gemtech one for point of impact shift – a normal phenomenon when you add a silencer to a rifle or pistol. While you could go nuts with different rifles, muzzle devices, ammo and ranges testing this, I kept it simple as I just wanted to get an idea of what to expect with point of impact shift.
I mounted the Gemtech flash hider and quick-attach muzzle device to a Daniel Defense DDM4V5 300 Blackout rifle with a 16-inch barrel and fired three shot groups at a target 50 yards down range. Ideally, I would have done at least 100 yards, but, hey, it was all the distance I had available at the time. I shot sets of three-shot groups unsuppressed using American Eagle 220-grain Suppressor 300 Blackout ammo and one of my supersonic 300 Blackout hand loads. This particular load uses a 125-grain Nosler Ballistic Tip projectile over IMR 4227 powder for a velocity of 1,971.3 feet per second from the DDM4v5. I then fired three-shot groups with the suppressor mounted, again using the same supersonic and subsonic loads. Using some “pretty close enough” math and measuring, I plotted the center of each of the groups so I could see the amount of shift.

Award for “most fun load” goes to American Eagle’s 300 Blackout Suppressor ammo. It made satisfying “thud” noises in the dirt berm down range.

For the American Eagle Subsonic ammo, the point of impact shifted straight down exactly 11/16 of an inch. There was no detectable lateral movement in the group. For the supersonic hand load, the group center shifted exactly ½-inch down and ¼-inch to the right.
Certainly, at longer ranges you would see more of a difference, but that’s irrelevant as the “suppressor shift” is a one-time adjustment. Zero your rifle with the ONE installed and just know what your minute of angle shift is when shooting unsuppressed. For practical applications, it’s small enough not to cause too much consternation.

Closing Thoughts

I really like this suppressor, probably because it doesn’t try to do too much. By limiting it’s intended performance, Gemtech is able to keep this can very compact for what it does. Compare the size to the SilencerCo Specwar 7.62 in the photo here to see what I mean. While possibly there for cosmetic reasons, I also appreciated the textured sleeve on the bottom half of the suppressor body. That makes for a good grip to mount and unmount this silencer, especially when you’re using a rag or suppressor mitt after it heats up.

BREAKING NEWS: Federal Court of Appeals to Review Important Gun Rights Decision

NRA-ILA GRASSROOTS VOLUME 23, NUMBER 9   LEGAL & LEGISLATION  NEWS BREAKING NEWS: Federal Court of Appeals to Review Important Gun Rights Decision The United States Court of Appeals for the Fourth Circuit announced this afternoon that it has agreed to an en banc re-hearing in Kolbe v. Hogan. As we previously reported, the Fourth Circuit’s earlier decision in Kolbe has the potential to invalidate Maryland’s ban on common semi-automatic firearms and detachable magazines.  The Kolbe decision is extremely important, as it is the first instance where a United States court of appeals required “strict scrutiny,” the most stringent form of judicial review, for a ban on so-called “assault weapons” and detachable magazines. The outcome is the re-hearing is too close to call at this point.  We will keep you apprised of further developments of this NRA-supported case as they occur.      NEWS Chris W. Cox: Freedom's Safest Place The Hollywood celebrities, political elites and billionaires who attack the Second Amendment want to take our God-given freedom away. Yet at the core of the Second Amendment is the eternal truth that no life is more worthy of armed protection than another. The National Rifle Association fights for the protection of these liberties. The NRA is Freedom's Safest Place.   GUN LAWS  LEGAL & LEGISLATION  SECOND AMENDMENT Second Amendment as Second-Class Right? A Dismal Warning A case involving the scope of firearm prohibitions prompted Supreme Court Justice Clarence Thomas to break his more than decade-long silent streak on the bench. Justice Thomas last asked a question in February 2006, but he made headlines on February 29 by asking a question during oral argument in the case of Voisine v. United States. Unfortunately, commentators seized on the fact that he spoke at all, rather than the troubling implications of what he had to say.    NEWS Pinocchio's Greatest Hits Hillary Clinton Always Does What's Right? CNN reported last Friday that former Congresswoman Gabrielle Giffords, now a gun control advocate campaigning for Hillary Clinton for president, told the news organization, “Time and time again, Hillary has done and said what is right.” But if you’re not so sure about that, you aren’t alone. Gallup reports that when asked for the first word or phrase that comes to mind when Clinton’s name is mentioned, 40 percent of Americans say “dishonest,” “liar, “don’t trust her,” “poor character,” “dislike her,” “criminal,” “crooked,” “thief,” “belongs in jail,” or “wouldn’t be good for the country.” And Giffords’ glowing endorsement of Mrs. Clinton was not the only truth-bender that gun control supporters were responsible for last week.   NEWS Primary Update After Super Tuesday, with 11 states completing their caucuses or primaries, the presidential race is starting to become a little bit clearer. Hillary Clinton won seven states and Bernie Sanders won 4. While this looks like, and is being hyped as, a big Clinton victory, her camp had really expected to win 10 of 11 (allowing for Sanders to win only his home state of Vermont). That same day, Donald Trump won seven states, Ted Cruz won three and Marco Rubio won one. The results help to solidify Trump as the leader, but it is closer than many believe. The primaries are races to earn delegates to the respective party conventions.  It takes 2,383 delegates to win the Democrat nomination and 1,237 to win the GOP nod. Most states with primaries or caucuses before March 15th, including all of the March 1st states, award their delegates on a proportional basis, so it takes a big win to gather up the majority of delegates in any given state.   NEWS  LEGAL & LEGISLATION Gun Control Supporters Distort Iowa Legislation on Youth Handgun Possession Willful ignorance of firearm function, culture, and law are well-known characteristics of the gun control movement. However, the principals in a recently manufactured controversy, surrounding legislation in Iowa that would allow properly supervised youth to use handguns for the shooting sports, have shown a particular disregard for the facts and prevailing law. Current Iowa law makes it a misdemeanor to transfer a handgun to those under the age of 21, with a few exceptions. A parent, guardian, or spouse over 21 may allow those ages 14-20 to possess a handgun while the minor is under their direct supervision, or while receiving instruction. Iowa has a blanket prohibition on handgun possession for all those under 14, regardless of parental supervision. Current law even prevents those under 14 from engaging in traditional handgun safety instruction.   NEWS Scotland Sets July Deadline for Airgun Licensing In a sad turn, the home of the Scottish Enlightenment continues to adopt benighted gun controls. On June 25, 2015, the Scottish Parliament passed the Air Weapons and Licensing Act, with Royal assent following on August 4. The legislation requires airgun owners to acquire a certificate or permit to continue to possess the devices. Late last week, Scottish officials announced July 1, 2016 as the deadline for obtaining the required documentation. Specifically, the law makes it “an offence for a person to use, possess, purchase or acquire an air weapon without holding an air weapon certificate.” If convicted, a violator faces up to two years in prison.   NEWS Has the VA Deprived You of Your Second Amendment Rights? NRA Wants to Hear From You! As we have reported several times in the past (including here and here), the Veterans Administration (VA) has been reporting to the National Instant Criminal Background Check System (NICS) the identities of its beneficiaries who have been assigned a “fiduciary” to manage their benefits. The VA claims that such determinations constitute an “adjudication of mental defectiveness” under federal law, thereby prohibiting the beneficiary (presumptively for life) from acquiring or possessing firearms. The NRA has for several years been supporting legislation to correct this unjustified infringement on Second Amendment rights, including the Veterans 2nd Amendment Protection Act (H.R. 2001, Rep. Jeff Miller, R-FL) and the Mental Health and Safe Communities Act of 2015 (S. 2002, Sen. John Cornyn, R-TX).   TAKE ACTION Michael Bloomberg is ALL IN to strip away your Second Amendment Rights! Are you ALL IN to make sure he doesn't succeed?! Billionaire Michael Bloomberg is in a spending freefall attacking our gun rights all across the U.S., on multiple fronts…in Congress, in state legislatures, and on the airwaves. Further, he’s gathering signatures and pouring money into anti-freedom ballot initiatives in states like WA, NV ME, and AZ.   In the ’15 VA elections, he spent more than $2 million on a couple of state senate races!  If he’s willing to invest that much in VA alone, imagine how much of his BILLIONS he will spend in ’16 all across the nation! VIDEOS   NRA CEO & EVP Wayne LaPierre: CPAC 2016 NRA Executive Vice President Wayne LaPierre urged the crowd at the Conservative Political Action Conference in National Harbor, Maryland to stand up for freedom this November and take back the country. He said the most effective and surest way to defend freedom is found in four simple words — Thou Shalt Not Lie — and he promised that the NRA would continue to expose the liars about freedom as they've been doing for decades. Truth matters, LaPierre reminded, and he noted that Americans are seeing right through all of the Obama and Clinton schemes because they know a liar when they see one. The NRA chief concluded by encouraging everyone to rise up and make a difference — standing up for truth and freedom — in this election.   Super Tuesday Victories In this News Minute from the NRA Institute for Legislative Action, Jennifer Zahrn reports that candidates endorsed by the NRA Political Victory Fund had a strong primary day, winning the vast majority of races where we endorsed.
