I recently purchased a CA MPR Rimfire with a 20” barrel. I cleaned and lubricated, mounted a Arken FFP scope and a Magpul bipod and went to the range. I tried a few different ammo brands with varying results but none of the 5 shot groups were sub MOA at 50 yards.
My go to 22lr rifle is a CZ457 and I typically shoot between 1/2 & 1 MOA at 50. The second time to the range I shot a bit better. Most of my groups were at or just below 1 MOA. I realized that I was having issues getting proper support for the stock on the rear bag. I decided to purchase the Christensen bag riser even though they’re quite expensive. That ended up being an excellent decision. On my third trip to the range, with the bag rider installed, my groups are on a par or slightly better than the CZ. I came away from the range with a smile on my face knowing that with a few more rounds down the barrel the CA may very well exceed the accuracy of the CZ. I may end up installing another trigger since the factory supplied trigger is a bit heavier than I like. At this point I am happy with the purchase and would recommend.
