The Grand Master Trigger Assembly

Available online!

The Grand Master Trigger Assembly is an excellent upgrade over the current factory 10/22* polymer trigger assemblies as well as a very innovative alternative to aftermarket offerings.  The kit version (includes the Power Match Bolt) not only allows the implementation of a last shot bolt hold open system, (with a special extended bolt release tab version CST 2nd Gen ABS), but also provides a superb fully adjustable match quality trigger unit as well. 

The Grand Master Trigger is fully adjustable for pull (1 3/4 to 3 lbs) and over-travel, features a innovative sliding safety, and a patented spring assisted magazine eject, (requires a modification to factory receivers), and now features a new wrap-around mag release lever.  It is available in either silver or black.

Clearance for the spring assisted mag eject feature is a simple procedure for any gunsmith and instructions for this procedure is included by Grand Masters, LLC.  The need to modify the receiver for the spring assisted magazine eject can be avoided all together by using it with our CST Rimfire Receivers, with the clearances all built-in.
