The KVP 40 S&W and 10mm BCG is a feature packed solution for your Blowback Carbine or Pistol. Our BCG is compatible with Glock 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 added a beefier firing pin retention spring to help lower the likely hood of firing pin breakage. The 40/10mm BCG’s feature the tried and true AR15 extractor system, which provides the needed power to pull even the stickiest PCC cartridges out. ***NOTE*** 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. .40S&W BCG Features: Glock or Colt Compatible USA made 8620 Steel Carrier Construction Nitride QPQ Finish Heavy Firing Pin Retaining Spring Weight: 14.6oz
