BRT custom tune gas port vs heavier buffer

[Bob Sacamano]

With the current trend from many barrel makers, prob would not even need to drill it, just run a tap through the gas port hole.

Hmm,

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

I agree with Clint.

THEORETICALLY it should work. But it makes my butthole tighten up a whole lot.

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

We've got a prototype adjustable gas tube that should work well with the pinned battle comp.

It drops right in without removing the gas block.

Very interesting. Have a Noveske 14.5 with a pinned BC in the parts box. Would be nice to put it back into service.

I thought I'd post an update for the gun that inspired me to make this thread.

I got her put together on Friday and ran a few hundred rounds through it today. I've concluded that I was likely over thinking the Noveske being over gassed internet talk. I measured the gas port at .080" compared to my 14.5 BCM upper that measures .077". I'm not an engineer, and have no idea how significant that is, but it feels good shooting it with an A5H2.

Also, I'm now in love with the Precision Armament EFAB.

What would the drawback be, if any, of going to a .073 from a .076 in a 16in middie?

Clint, it's in your block with your port... if that helps.

When I first put it in, I starting playing the spring/buffer game using .223 PMC Bronze and 5.56mm Magtech 77s.

Preface this with no malfs of any kind during this process.

Using the green spring and the -2, the .223 would eject to 3 and the 5.56 2ish. Went to the -3, and they moved forward 1 o clock respectively.

Now think maybe the -2 and a smaller port would get it where I'd like it.

the .073 should run nicely.

Sounds very interesting.

As a guy who makes a living drilling holes in things, that's what I'd do. Drill only part way, finish tapping with a flat bottom tap and if the Microport stood a little proud, I'd blend it. The use of a drill stop will minimize the risk and would be easier than removing a pinned muzzle device.
