Custom rifle and pistol AR build kits for the most popular calibers.
You've gotten all learned up on how to build an AR-15 (because you read our awesome parts guide). Now you're ready to pull the trigger, so to speak, on a build kit. We've got your six with dozens of quality, custom-built AR parts kits that include everything you need except the lower itself. Of course, you can grab an 80% lower and fabricate it to make a truly one-off shooter.
The AR platform can serve virtually any purpose: Hunting, sporting, close-quarters and personal defense, precision and long-range, suppressed and subsonic, you name it. That's why we've carefully selected and crafted every build it in a plethora of the top calibers AR owners love to shoot. We took care to make sure each caliber's kit provides the optimal twist rate, barrel length, weight and parts for superior accuracy and reliability, no matter what grain weight you hand-load or buy to shoot.
There are loads of AR makers and distributors selling all kinds of flashy-lookin' AR kits. But we know what makes or breaks a great AR-type rifle or pistol, and we consider every spec that goes into each part, from muzzle to buffer:
Your custom AR kit awaits.
