Chopping a 7.62x39 Barrel?

[skoodge]

Why not cut the current barrel first to see of you got lucky with a decent barrel. My 104ur had a pretty centered bore when it was cut, while my 107ur was slightly off. It wasnt too too bad though. Not compared to one I've seen on the ak files forums. Might not have to buy a new one if you don't have to.

You should consider replacing the bbl with a US mfg one from Green Mountain.

I should be getting papers back on a SLR107-UR in the near future and was wondering if anyone had any recommendations for getting the barrel cut down? I've seen videos of people doing it themselves but I'm not sure I want to go that route. Would hate to end up with something that keyholes, especially since it'll be wearing a suppressor at times.

Thanks!

It's really not rocket science. You can rent the tools to cut the face of the muzzle true in relation to the bore and then crown the muzzle. The hardest part of the whole thing is getting the gas block off, getting the restrictor plug out of the gas port and the getting the whole thing back on and repinned without it being canted.




I did mine on the back patio. The only annoying part was dealing with dull rental cutting tools for the muzzle and the crown. After that experience I bought my own. The gun worked well enough to get me 3rd out of 63 or so shooters on the 400yd stage at the Oklahoma Run&Gun back in 2013 or so.

Ummm... cfortune did this already, I believe, although not very scientifically.

It's pretty damn loud.

Lapping compound and a giant brass button head screw chucked up in a drill?

Didn't have a big enough brass screw. Used a galvanized carriage bolt with the numbers filed off the head.
