With our wide variety of upper-build kit options, your pistol can be as agile, compact, and loud as you want it to be.

GM AR-15 .223/5.56 Nato 5", BR 1:5 Twist Barrel
This barrel is 5-inches and operates on a Micro gas system and is chambered for 5.56 Nato It features a 1:5 twist rate which works well to stabilize heavier projectiles. It is made from high-strength material to keep this barrel tough and reliable and perfect for your next pistol build.
