BRT custom tune gas port vs heavier buffer

[sig1473]

I have a Noveske 14.5" ML and it is on the gassy side. I'm currently running a regular RE with a H3 buffer. I believe the gas port size is .080.

Sounds like a couple sizes larger than needed.

A custom tune gas port can fix it right up.

My experience points to properly setting the gas flow and using the A5H2. Heavier buffers start to push the AR around more than needed as the action cycles.

Went out and tried running a rifle set up for an A5H2 with an A5H3. The muzzle dip was pretty easy to note after getting used to the A5H2. I was pretty surprised.

Back in topic, I'll be doing a gas port in an overgassed barrel rather than go up a buffer weight.

It's a Factory upper with a pinned/welded BattleComp

Unpinning a pinned/welded muzzle device with a dremel is actually much easier than people think. Just go slow, and only remove as much metal as necessary to get the pin to loosed up.

Unfortunately you will sacrifice your BattleComp.

Clint,

I'm glad you're on this thread. I have read quite a bit about people talking about gas port erosion.

How big of a problem is that really, and how do your gas port inserts affect it?

I have shot out a few barrels, and as far as I know gas port erosion has never been an issue.

Yeah, I'm not getting rid of a Noveske marked Battlecomp hence the frowny face in my post.

One option is that case is a two piece clamp on gas block.

Clint, what about sliding the existing gas block forward and drilling and tapping the barrel gas port to accept the micro port?

Hmm,

Might be possible, but seems like a theoretically good method to actually ruin an otherwise good barrel.
