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.

MrGunsnGear shared the database on his Facebook page that one of his viewers complied. The data base has the weights (in ounces) for hundreds of various AR-15 parts from many companies. From upper receivers and parts, lower receiver parts, bolt carrier groups and parts, barrels, rails, muzzle brakes, buffers, stocks, optics and mounts, weapons lights, magazines and other accessories. A lot of time was spent on this database, a big thanks to those who put this together!

    Some of us actually are looking for heavier guns. I have a pacemaker implanted right where the butt fits against my shoulder, so I need to minimize recoil. Padding on shoulder and padding on butt only does so much. I'm currently looking at heavier target-style AR-15 variants.

      @Rex The PWD would be just as helpful for you as it is for the ultralight crowd. Sure, the focus *started* with light stuff, but we don't discriminate in the PWD anymore. We've got bull barrels and comp super-heavy rails too. All you have to do is scroll to the bottom of the list instead of checking out what is on "top". :)

    You're welcome, Ray. I do what I can. :-) The data for the PWD comes from many sources, and users have added their own parts to the list, but for just pure data entry and researching www sites, and watching youtube reviews, and collecting data from forums etc, I did about 95% of the 'work'. I have some OCD, might as well put it to good use!
