There is are subtle angles on the feed ramp and the space between the feed ramp and the barrel that have to be maintained. Also, there may not be any need (gun most likely will work fine as is), to polish the ramp except that some people cannot bring themselves to leave things alone and/or like the aesthetics of a polished ramp. If it functions and there is no indication that there is a problem, you risk (does not always happen), inducing malfunctions that were not there before.I don't see how polishing your feed ramp is going to make it a pos?
