Chopping a barrel

[LowSpeed_HighDrag]

Guys,

as always, solid advice on M4C!

So, I am chopping the 6920 barrel because the gas port is smaller, thus giving me the perfect suppressed barrel.

I did not go with an aftermarket barrel because most gas ports on short barrels are opened up too much.

I will get ahold of Adco and let them know I want the shoulde where the barrel begins to taper.

I cant do 10.5, because the BCM MCMR 10 is actually a 10.4" rail....

Can somebody explain to me the benefits of 5/8x24 vs 1/2x28?

The barrel is thicker at one of the most critical points - the muzzle.

Sounds like you have already moved forward with the 6920 barrel, but FYI that second link SS posted is a reduced gas port barrel specifically made for dedicated suppressed weapons.

I was actually wondering the same thing.

$219, plug and play, no muss, no fuss.

OP, Good Luck.

The RGP Sionics GP diameter is still too big for dedicated suppressed use with 5.56 IMO.

Again, I am curious. What was your experience with those barrels? How did you have them set up?

Mine run just fine.

He can only run a suppressed SBR for a duty gun. I told him a cut down 6920 barrel would run better than any other option.

Exactly right, and I'm dutifully following your advice.
