Cornerstone thumb ledge

Written on Jul 04, 2020

The cornerstone safety thumb ledge greatly improves accuracy and quick target acquisition. Not only is it more comfortable than the factory safety, it is smoother as well. It was a little tight at first (i also have the volquartsen accurizing kit installed which changed some tolerances of the internals as well) but once you install the new safety and oil/clean it, it works perfectly. Awesome product. Well worth trying.

Tandemkross game changer PRO

Written on Apr 22, 2020

Noticeably reduces muzzle flip for quick transitions between targets. Very easy to clean after shooting cheap/dirty .22lr ammo. Im running mine on a Ruger MKIV 22/45 LITE. Tandemkross has excellent customer service if you have any questions they will take care of you. So far ive purchased 5 Tandemkross upgrades for my MKIV 22/45 and will be keeping an eye out for new products from them.

Volquartsen trigger kit Ruger MKIV 22/45

Written on Apr 20, 2020

Huge improvement over the factory trigger. Noticeably lighter pulls and shorter reset. Make sure you use the correct bushing or the safety will be very hard to actuate. You cant go wrong with any Volquartsen products.

TruGlo Tru-tec 3 MOA RDS

Written on Apr 20, 2020

Extremely impressed with quality of the glass and the emitter is plenty bright even without full brightness turned up. Holds true zero on a Ruger MKIV 22/45 Lite with well over 1500 rounds so far. The adjustment tool however broke on the flathead side while tightening the lockdown screws. I would say this is a strong contender against the Vortex Viper (which i also own so I can compare). Overall happy with this purchase for my Ruger.
