Getting ready to order the hand Chanfering and lapping tools from Brownells.
I want to make sure I order the correct angles.
Will be ordering all tools with the 30 cal pilot since I guess that's the closest available.
Any feedback would be appreciated.
Looks like both my Romanian and the Saiga have compound angles , maybe 90 and 45, or 90, 79, and 60.

On an AK, it really doesn't matter what angle you get, since the rifles are not anywhere close to tack drivers. Typically, I use the 90 degree cutter, and have had excellent results with it on everything from FALs to varmint rifles. The 90 degree cut is the least fragile cut for the effort. The only other cut I would recommend is a recessed crown, and that is very hard, if not next to impossible with the Brownell's hand cutters.

You can get the 11 degree if you want to, but every time the muzzle gets dinged, you will be "dressing" the crown. The 90 degree just holds up better.

Forgot to mention that a muzzle brake will be threaded on and soldered on these builds.
So, a 45 degree chamfer at the bore wouldn't hurt ? Or should I just lap the sharp edges off ? 45 degree just at the corner like this : |----\ /----| would that be ok ?

Yep, that would be fine.

I thought that the 30 cal pilot was supposed to keep all cutting concentric with the bore.
I haven't tried it yet, so I don't know.
