AR-15 Parts Weights Database

When it comes to building an AR-15 weight is a factor I always consider. Unless you’re building a long range rifle that will only be shot off of a bench I believe lighter is always better.
A good way to shave off ounces from your AR build is to use a lightweight lower receiver and lightweight bolt carrier group, or if your budget allows it carbon fiber or titanium parts. If you’re not building a race gun or you don’t have a large enough budget you can save weight by simply using only iron sights and not adding every tactical do dad all the operators use, that’s hard to do I know. If you are shopping for parts for your next AR build or you plan to update your existing AR-15 check out this extremely thorough AR-15 Parts Weights Database.
