I suspect I'd probably be more concerned about excessive lead buildup from the 22 ammo used more than the wear on the surface of the barrel or rifling itself, and the effect that lead could have on the rifling.



I am using a 5.56 chamber in my AR. Would that be an issue?


I am glad you mentioned that because that is a conversion kit I had not heard of yet. It looks like it could be a good one, and is cheaper than other options.
Could be right on dedicated lead removal cleaners and definitely right on over using a brush, but you really don't need to do anything that involved on cleaning the bore out.

Fine on the 5.56 chamber, just wasn't sure if you had a Wylde or if it could pose a problem. The upper i ended up dedicating to the adapter is snug to close on the lower and I suspect the reason is a .223 Remington chamber. Adapter drops right in known 5.56 chamber barrels without issue.

Reasonably sure most commercial .22 adapters use the now expired Atchisson patent.(also assume Army and USAF adapters are slightly different based on magazines at least).

Other than occasional surplus Army/USAF adapters, Ceiner kits were really the only option on the market for decades. I would go any other kit at this point in time after I dicked with my Ceiner (after talking to them on the phone and in person early on) for about 10 years before getting it to function as reliably as a rimfire can be expected to be and that was due to advice I got from Black Dog Machine who I do recommend.
