Wait what? They have a warranty on 10/22"s? I have one that is 40 years old, if something broke on it I would replace it myself. Many many bricks of ammo through it. Can't remember if I have cleaned it once or twice since I bought it,When you drill a hole in the back of the receiver it voids the warrantee. If you want a kit to do it anyway, try brownels.
Well it is a 10/22 and as such the tolerances are a bit to the loose side so it is unlikely that it will need cleaning all that often.How are you guys doing it?
From the muzzle with a rod or with a pull thru??
There was another company that apparently infringed on the Ruger patents - and was making them with the hole in the back. Think they were sued out of business? Did Ruger ever do this? I've not seen one.There used to be place in the rear of the receiver that got a small hole milled though so it could be cleaned from the breech end with a conventional rod. Not sure if that's still a thing, or if it got axed for reasons. It still required disassembly including bolt removal, of course.
Those are nice rifles. Nicely finished receiver and bolt compared to Rugers castings.I think Thompson Center briefly made a not so subtle knockoff of the 10/22
