More Better
The Ruger Mark IV 22/45 Lite already being a fine target pistol, this extended bolt stop makes it even easier to lock back and release bolt. Just one of the many great accessories Tandemkross offers.

I have these on all of my 22/45's. They work great and are easy to install. You can't go wrong getting yourself an awesome upgrade...

Bolt Stop
Nice upgrade. Not a drastic change, but gives you a very nice advantage to the somewhat difficult stock bolt stop. Super easy to install, Love it.

Ruger 22/45 bolt stop
Great addition to my 22/45. Well made product, not cheap stamped item. Super easy install.

Easy to install and use
Super easy to install and makes it much easier to unlock the bolt, as someone with larger hands. All gives those with weaker hands more leverage

Big upgrade
Since I bought my Ruger MKIV 22/45, I haven t been able to release the bolt using the bolt stop until I installed the Bolt Keeper. It s now a breeze. I bought the black one to match my gun. Highly recommend.

Bolt Keeper
The "Bolt Keeper" is exactly what I needed to hold my thumb. It is very well constructed and it was a breeze to install and looks great, especially in the red color. Thanks, gary
