Although there is enough clearance inside the reciever, I would suggest that you just leave it alone. Keep in ming that this internal coating, will eventually start to flake off and then could be a problem. That is exactly what is happening to the coating on the latest issue of the 10/22's. It starts on the inside of the port and creeps out. ....My question is can the inside be painted or do i leave it alone and only worry about the exterior of the receiver?
I don't know what generation you have and I prefer the older ones, to the new. Throughout the years, there have been many coating or anadizing processes. I don't know what you have, so for now, I'd say to leave it alone as I don't think you have a problem. Keep in mind that you can always carry your new coat, inside the side port. What say you??? ...So should i strip the inside and then leave it alone si i have no future problems......
