CMMG Barrel and BCG Kit 4140CM SBN Drop in Barrel 5.7 x 28mm 8″ Barrel Black
Product description
The 8" 5.7x28mm Barrel and BCG Kit is perfect for building an AR pistol or SBR in 5.7x28mm using CMMG’s patented Radial Delayed Blowback operating system. Unlike typical direct blowback systems Radial Delayed Blowback not only reduces the weight in your BCG but it results in less felt recoil than a straight blowback system and still provides essential features like last round bolt hold open. CMMG’s 5.7x28mm Barrel and Bolt Kits are designed to be assembled into a Mk4/mil-spec AR15 upper and work with either a CMMG Mk57 lower receiver or Mk4/AR15 mil-spec lower receiver (when using CMMG 5.7 AR Conversion Magazines).

Size measurement
Choose the right size by following these simple instructions. The best time to measure your feet is in the evening.
1. Stand on a piece of paper against a wall with your heels gently touching the wall.
2. On the paper, mark where your longest finger ends (you may need someone to help you with this) and measure the distance from the mark to the wall.
3. Measure the other leg in the same way and use the measurements to select the appropriate size in our table.
