Gunsmithing FEED RAMP WORK? AR15/308

[redirt78]

Found some threads on this but looking for recent feedback <span style="font-weight: bold">especially if you have a POF 308</span>

What, if anything did you do/have done to yours?

What are the pros, are there cons?

My AR 5.56 (DTI barrel) mars and scars my bullets. I think it is the feed ramps (could be wrong) that cause the scarring and I have read a little about polishing them. Might give it a try but it really isn't set up to be a long range weapon.

<span style="font-weight: bold">I am interested</span> in what I can, should or don't need to do for the <span style="font-weight: bold">20" POF 308</span> I am going to have (maybe it has different ramps, probably something I should find out).


At what range do the slashes and scars left on the bullets really start to show?

Anyone who knows a hell of a lot more than I do is welcome to post.

Thanks for the help.

Here are a few links, I did look for a while

Thanks, looked close at the ramps on my 5.56 and can see copper dust/shavings from where its digging in.
