I just traded my Polish Tantal AK-74, for a used Ruger SR-22 rifle. It is an accurate rifle {free floated barrel}, not to light and whippy, just the way I like it. I have a problem with the top reciever scope screws coming loose. One was replaced by the original owner...and I stripped that one. Will have to order another set of allen bolts {3} for the top of the reciever; and too find a way to keep them tight. The lower reciever screw bolt tends to come loose, but not recently...since I blue Locktited it. The metal lips, and followers, on the Ruger Mags tend to last forever; so far. It loves Blazer ammo!!!
The followers on the Pro Mags, seem to wear out very quickly {50 round drum}.
Operating the forward trigger guard button safety, on the SR-22, is slower than operating a AR-15 safety.
I may never go back to my two dedicated 22 AR-15 uppers, cause they have many FTE's, a few OOB's and the magazine lips wear out faster than anything.
No FTE's or OOB's with my SR-22, after about 8,000 rounds. The only negative's are the top reciever allen screws coming loose, and the location of the safety.
