CST 2nd Gen CST Auto Bolt Stop for Ruger® 10-22®

CST Auto Bolt Stop system provides: *A last shot bolt hold open function with factory Ruger® magazines with no mods to the mag required. *Magazines can be removed and reinserted with the bolt in open position. *Allows an automatic release once a loaded magazine is reinserted by pulling the bolt to the rear and letting it go. *Eliminates the need to “count your shotsâ€, the final discharge will have a distinctive sound and recoil impulse telling you that your rifle is empty. The CST 2nd Gen Auto Bolt Stop will include full installation instructions. The following is more helpful information. Always following safety protocols by verifying the rifle is completed unloaded with magazine removed. Remove stock (make sure safety button is centered to avoid damaging the stock), trigger assembly via two cross pins, and replace the bolt with the Power Match Bolt completed by reinserting the bolt stop pin. You are now ready to install the 2nd Gen Auto Bolt Stop into the trigger housing. Step 1: The factory Bolt Lock (left), Ejector (top right), Ejector Pin (middle right), and Bolt Lock Spring (bottom right) are all removed from the trigger assembly. To remove the Bolt Lock and Bolt Lock Spring, the Hammer will also need to be removed. Reinstall the Hammer properly engaged with the Hammer Strut and Spring after the Bolt Lock and Bolt Lock Spring have been removed. Step 2: With the magazine latch pin moved slightly to the right, insert the CST 2nd Gen Auto Bolt Stop into the trigger assembly from the top. The lengthened Ejector/Lever will slip into the trigger assembly ejector slot. Take care that the Auto Bolt Stop torsion spring stays along the left side wall of the trigger assembly on the way down. Step 3: Insert the magazine latch pin into the provided cross-hole of the Auto Bolt Stop. Check that the bottom leg of the Auto Bolt Stop torsion spring is sitting on the correct surface inside the trigger assembly and not in the safety channel just below. Auto Bolt Stop should rotate freely with no binding in the ejector slot.
