Has anyone chopped down any of the 16” Galil Aces? I’m leaning toward another pistol, I just wish the barrels were slightly longer. Wondering if you had to open the port if you go from 16” down to 12” on the 7.62x39 or the 5.56. Thanks.

I haven't done an ACE.  I have a SIG 556 Patrol that I SBR'd.  It went from 16" to 10" and then wouldn't work reliably on either regular or adverse settings.  I had a gunsmith enlarge the gas port holes on the plug and it runs like a top now.  I know it isn't the same gun but the 556 is also an AK type operating system.

I would be interested in cutting down my 16" 5.56 ACE enough that the suppressor mount could be pinned and welded and get back to 16".  That wouldn't be much of a change though.  I just find most 16" rifles to feel overlong with suppressors on the end.

Is it real complicated to cut and thread a barrel while it’s still in the receiver and open the port up? I can’t decide if I should just pick the other caliber pistols up, or grab the rifles and go this cut and thread route down the line. Really wish the barrels were like 10” or 11”.

Im having Class 3 Machining (you can find him on facebook) take care of mine. Hes done a ton of work for me and well priced - specializes in AK stuff too

Will report results. I assume given the harsh overgassing of these rifles i assume it would still work... but im only going from 16 to 13.7 with a pinned NOX
