Hi all.

So I have a Colt MT6400c...excellent rifle, but EXTREMELY loud...and I think it's due mostly to the huge compensator / muzzle brake. It deflects a lot of muzzle blast to the left and right, as well as back to the shooter...people at my range hear (and feel) the blast, and think it's a .308 AR.

Anyway, what different muzzle device can I buy to make it quieter? (No ,not a suppressor).

Keep in mind I live in NY and can't have a flash hider...and the MT6400c series have pinned muzzle brakes also.

Thanks for any help...I am new to muzzle devices.

I also posted this in AR15 discussions, but I figured us NY and NJers would know what devices were best for post ban rifles.

That says it is also a flash supressor...that wouldn't be legal would it?

ETA: I see the BATF classified it as a non-flash supressing device...cool.

BUT - How would I install this on a the MT6400c barrel? Would I have to get the barrel threaded?

And will it do a better job of directing noise downrange? NOISE is my primary concern.

it definitely sends noise forward. as for installing it, send your upper and the comp to adco. they do fantastic work.

Hey,

I bought a 6400c a while back and wanted to make the same modification you're asking about.

Because the 6400c barrel has not got the traditional threaded end, I went overboard and swapped barrels before I put the PWS brake on. (I had ADCO swap out the 6400c barrel for a neutered 6920 barrel.)

Do you have to do this? No.

I just didn't want anyone permanently altering the 6400c's barrel...which they would have to do to put on a new brake. The original barrel is safe and sound, covered in oil, and hiding under my workbench.
