Try it without the bullet guide. It probably wont work, and you will have to do it anyway.
Almost all, if not all AKs have a bullet guide rivited to the trunnion just below
the chamber end of the barrel.
You need the bullet guide / feed ramp IF you want to use standard AK mags without having
to modify each and every mag to work.
You may not be able to see it very well, but it is there.
They are available through K-Var, or you can make one with a hack saw,
and a file in about 10 min. Make sure you fit it properly and test feed it with ammo out of
a mag to make sure it does feed. Be sure that the bolt does close properly with a live round
in the chamber. The bolt can drag against the bullet guide if it is to thick.
The bolt will not rotate properly to close completely.
The conversions are very easy to do.
