Kaw Valley Precision Blow Back Bolt Carrier Group 40 S&W/10mm Medium

The Kaw Valley PrecisionA(R) Blow Back .40cal / 10mm Bolt Carrier Group (BCG) is a feature-packed upgrade for your blowback carbine or pistol. GlockA(R) or ColtA(R) compatible, this BCG features an 8620 steel carrier with a nitride QPQ corrosion-resistant finish. A heavy firing pin retaining spring helps lower the likelihood of firing pin breakage while the tried-and-true AR-15 extractor system provides the needed power to pull even the stickiest cartridges out. Made in USA.Note: Many aftermarket drop-in triggers use modified hammers and can be temperamental in Blowback systems. For the most consistent results, a mil-spec fire control group is recommended. However, in Kaw Valley Precision's testing, these aftermarket fire control groups should work in most circumstances: POF, HiperfireA(R) EDT and 24 series, GeisseleA(R), TimneyA(R), Rock RiverA(R), and SpikesA(R).
