CZ / CZ-USA 455 Varmint Tacticool Suppressor-Ready Update

Several weeks back I wrote about my recently acquired CZ / CZ-USA 455 Varmint Tacticool Suppressor-Ready .22LR rifle. I originally put a Weaver Optics T36x40mm fixed power scope on it to test it out, since it was the only scope that I had laying around.

I ended up shooting in an NRL22 / Club .22LR match at the West End Gun Club in mid-December. In order to participate in that match, I took the Vortex Optics Razor HD Gen II 4.5-27x56mm EBR-2C MRAD off of my Remington 700P .308 ATAICS and mounted it on the CZ 455.

While the variable scope was a necessity, the Razor HD Gen II only goes down to 32 yard parallax, and was difficult to use at 25 yards. Since I figured I will need a variable power scope on this rifle and due to the fact I lack a spare variable power scope, I committed to the Vortex Optics Viper PST 5-25x50mm FFP EBR-2C MRAD.

I went with the Viper PST 5-25x50mm FFP EBR-2C MRAD since it goes down to 25 yards for the low end of the parallax adjustment, which is going to be good enough for the precision-style .22LR matches that are starting to emerge.

The Viper PST 5-25x50mm FFP EBR-2C MRAD comes with less frills than the Razor HD line of scopes, which is to be expected with the cost difference in the Viper PST and Razor HD tiers. Simply the scope, the bikini-style scope caps, and documentation.

I ended up getting a set of American Rifle Company M10-1-00-30-24 rings, which are 30mm diameter and 24mm tall (0.94″). I like the simplicity of the ARC M10 single screw clamp design and they sit nicely on the Area 419 CZ 455 scope base.

I took the setup to an unfortunately windy day at the range to get everything sighted in and the new scope setup is zeroed in.

Anyway, this is the current setup for my CZ 455 Varmint Tacticool rifle.

I should also mention I modified the trigger with a Yodave trigger kit. It is basically an $18 USD (currently) kit that contains four (4) springs, four (4) ‘shims’, and a roll pin to replace a trigger pin. Essentially, each spring is a different tension and each shim is a different thickness. You use a combination based on trial and error until you find one that provides a safe, light trigger pull. I ended up using the thickest shim and the second heaviest spring of the four, which brought trigger pull weight down to 1-1/2 pounds with zero creep. Definitely much better than the OEM 4-1/4 pound trigger pull. The sear is safely engaged each time it is cocked.

I anticipate I will be getting a Masterpiece Arms CZ 455 chassis in the next few months. I would really like to have a rimfire rifle in a similar ergonomic configuration as my Mausingfield custom rifle build for more effective practice/training sessions.
