AK47 feed ramp

[fchavis]

A friend of mine recently bought a romainian AK. As a result of using one of the (slightly out of spec) mags we found that the noses of rounds were being deformed as a result of the chambering process (even through the good mags). I then took a closer look at the action and found that rounds were hitting the mouth of the chamber at a near orthogonal angle, and only getting into the chamber by force of the return spring.

My question is this: can I remove a bit of metal from the chamber/bbl to make a feed ramp without compromising chamber support? With about a half a mm, I think the whole thing could be vastly improved. Has anyone done this? It seems like the sort of thing that everyone with a bit of savvy would do to improve their rifles, unless it was unsafe.

Thanks,

You can POLISH, but when you start to remove metal you can get in real deep, real fast.

I sent mine back to Century because it would do the same thing as well as not feed HP's. They sent it back to me 2 months later after grinding a rough "ramp" into the bottom of the chamber. It still deforms bullet noses and feeds HP's about half the time. Down with Century!! Don't buy from them.

From what I've seen, that's actually not an uncommon mod for AKs. You just have to know what you're doing; break the edge, but don't grind past the case head or you risk becoming very sad.
