I have been shooting the CCI "Quite-22" for a few years out of a CZ 452 Lux. With the long barrel, the neighbors can't here it standing in the yard. The repeatable accuracy is excellent. Zeroed at 40 yards for the local squirrel population. 1/4 to 3/8 inch group with a 4-14 Burris rimfire. Head shots out of the kitchen window are routine. You must know the trajectory well. At 710 fps, they drop quick.
