Designed to maximize accuracy and reliability while running a suppressor. Package includes spring, cap, bushing, guide rod, and thread adapter (1/2-28). Our stainless thread adapter has our built in SAC accurizing feature and will help keep the barrel snug in the bushing. Spring tuned for suppressed reliability! Recoil buffer is included.
This package is designed to work without using the barrel screw. This eliminates the problem of changing the point of impact every time you re-torque the barrel screw.
