The Kaw Valley Precision 9mm BCG is a feature packed solution for your 9mm Blow Back Carbine or Pistol. Our 9mm BCG is compatible with either Glock or Colt style magazines. The carrier is constructed of US made 8620 steel, with a Nitride QPQ finish. The QPQ finish offers excellent wear and weather resistant properties that are superior to lower grade phosphate finishing processes. We've also added a beefier firing pin retention spring to help lower the likely hood of firing pin breakage, that is common in other 9mm BCG's.
Many after market 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 our testing, these aftermarket fire control groups should work in most circumstances: POF, Hiperfire EDT and 24 series, Geissele, Timney, Rock River, and Spikes.
