I am looking in to building my first ar-15 and since the 7.62 round is known to have bad feeding issues I was wondering if your uppers and barrel extensions have m4 feed ramps in them. I have herd they don't and that they did  so if not is that an option to have done?
Thanks |

That's an easy question to answer, the older run of barrels do not have M4 feed ramps, the newer runs do. 20" 7.62x39 barrels still have standard extensions, the 16" versions should all have the M-4 ramps. If you don't have extended feed ramps, you can always Dremel them in, but you'll remove the hard coat anodizing in the upper. Some companies still cut them in that way, but not us.
