im guessing cr5 you refer to me saying my sr22r had less failure stock then 2 in 800 as per your xcr, i did run a wet wipe in the chamber every few hundred rounds and a lil oil only because of the nature of rimfire, and probably had a couple in 1000 rounds plus. my sr22r works flawlessly now, its been running great after the polish. i bought 6 cases from eagle hunting and i only have 4 left. ill replace the extractor soon and im well over 10 000 rounds without a jam. in the 22 action rifle match i believe i was the only one without any ftf or any problems at all. i did however run a wet wipe every few hundred rounds and add some oilo ya and i stoned the trigger for a 4 poundish pull. awesome little gun, id recommend one to everyone. ive also polished my 870 and glock 21 gen 4, the bushy is so awesome that it doesnt need anything but a lil oil.
I don't own an XCR but I've put a lot of rounds through 4 different ones from an early first gen to the newest model before the keymod plus quite a few through an XCR-M.
I like my ACR better
