Kaw Valley Precision Blow Back .40cal / 10mm Bolt Carrier Group

The Kaw Valley Precision® Blow Back .40cal / 10mm Bolt Carrier Group (BCG) is a feature-packed upgrade for your blowback carbine or pistol. Glock® or Colt® 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, Hiperfire® EDT and 24 series, Geissele®, Timney®, Rock River®, and Spikes®.
