The receiver is machined from a solid billet of 416 aircraft grade stainless steel. During the machine process they are stress relieved and then finish hardened for 24 hours using the plasma nitrate method which is used in aircraft manufacturing. This specialized hardening process adds durability and longevity that is unheard of in the gun industry. The G1 receivers are also built extended which offers additional strength.



Unique inspection and lubrication windows on each side of frame.




The CSMC G1 has ventilated top ribs which are tapered from 10mm to 8mm with center channel for instant sight picture alignment. The ribs are installed using bronze brazing and laser welding with high point of impact for constant target visibility. They are built with a unique, enclosed and raised breech face for zero head space issues and added strength.



The CSMC G1 barrels are machined from 4140 steel, and over-bored to .736 bore diameter. Precision honed on machines for the G1 to achieve precise concentric bore.21. Barrel lengths for the G1 are available from 26”-34”. Barrel chambers are 2 ¾” with extended long forcing cones for reduced recoil.
