All the issues with the original CST Auto Bolt Stop including compatibility issues of the new "MIM" factory bolts, modified magazine requirements, and incompatibility of high-cap magazines has finally been eliminated with the latest 2nd Generation Auto Bolt Stop system.  Working closely with Grand Masters, LLC, a true match quality CNC bolt replaces the economy bolts and also provides the correct clearances and features built in for the 2nd Generation system, providing a last shot bolt hold open function without the need of modified magazines.

Easier to install, and greatly enhanced reliability make the CST 2nd Generation Auto Bolt Stop your first stop for upgrading the function of your 10/22 rifle!

Installation instructions provided.  Will install in either the polymer or aluminum trigger housings, as well as aftermarket triggers that duplicate the factory design.  (Designs that deviate and rearrange internal components will not work!)  Only Ruger BX-25 magazines are recommended for high-capacity magazine use.  We also recommend using the factory bolt stop pin versus common buffers for better reliability, (decreased bolt return velocity).

For those interested in upgrading the trigger assembly, we highly recommend the Grand Master Trigger Assembly with the CST 2nd Generation Auto Bolt Stop pre-installed, (available in kit form for maximum savings).
