TandemKross Ruger Mark IV 22/45 Lite Race Gun 22 LR 4.5" 10rd Pistol

The TandemKross Mark IV 22/45 Lite Race Gun starts as a Ruger Mark IV 22/45 Lite and comes fully assembled with TandemKross upgrades already installed, ready for rimfire competition out of the box. It is a semi auto chambered in 22 LR with a 4.5" stainless steel threaded barrel wearing a Game Changer PRO compensator. The serrated slide is black anodized and takes RMR, RMSC and Delta Point Pro pattern red dots, and a fiber optic front sight is installed.

The list of TandemKross parts is long: an Accelerator forward thumb ledge, a Blast Pack fire control group, a Bolt Keeper extended bolt stop, a Cornerstone safety thumb ledge, a halo charging ring and hiveGrip. The thumb ledges give your thumbs a place to ride and press against muzzle rise, the extended bolt stop is easier to reach, and the charging ring gives you more to grab when you rack the bolt. Two 10 round magazines are included, and the pistol comes in a TandemKase pistol bag. You get a finished rimfire race gun instead of a parts list and a weekend at the bench.
