Comment:
This is one of the best performing trigger groups on the market that is done right and performs as claimed.  Light 3.5 lb. trigger pull that literally breaks like a rod of glass.  Yet robust enough to withstand thousands of rounds of heavy duty use.  Single-stage release for competitive shooting that breaks instantly on contact.  Bench tested then test fired with 20 rounds of ammunition.

Easy Installation:

Allow 20 minutes if it is your first time.
