Will AR comp fit Mini 14?

We need a pic if possible, none of my minis (14 and 30) ever had a bayonet lug.

Did some searching and the Mini 14 was never made with a bayonet lug. The Ruger AC-556, a select fire version, was made with a bayonet lug to accept the M7 bayonet. Some further searching shows that the Ruger Mini 14 police model GB, a semi-auto, did come with a bayonet lug. Perhaps that is what you have.

The older Mini 14’s and AC556 machineguns used a 9/16X24 right hand thread pitch for their muzzle devices.

AR Muzzle devices (for 5.56 caliber rifles) use a thread pitch of 1/2X28” so they (AR compensators /brakes) will not be compatible.

I believe the AC5.56 is what the A Team had. Lol. I think that’s a GB that you have. I thought those were worth some money.

The device on the muzzle of mine looks a lot like a birdcage style that is found on an M-16A1. You'd have to check the threading.

..,seems steep but I am in ca ) the flash hider had been removed for legal compliance.

I wouldn’t break the law just to put a knife on the end of a rifle. How about you get a machinist to just drill and tap a hunk of barstock and turn it so the OD will go inside the ring on the knife?

You can legally have a compensator or a brake but not a flash hider, right?

There are probably other .223 brakes and comps threaded for 9/16x24, but none come to mind. How skilled are you with tools? Do you know any machinists or really anyone with a lathe or milling machine? Even a drill press and enough time and ingenuity would probably work.
