DD 16” midlength gassing

Or, be confident that when you buy a top shelf rifle, the engineers know something, and just shoot it.

Agreed

I thought that’s the gas port size of their 14” midlengths.

I have one and it also gauged at 0.076"...

Or, pop the gas block off and discover that damn near every ‘top shelf’ manufacturer ports barrels for the dirt clod Tula crowd.

I'm with 17K. Colt did it right on the 6960 at .071.

Maybe. But it sure seems like every topic about “hey guys, I have a gun that eats ammo” devolves into ****ing with buffers pretty fast.

There's probably not a discernible difference between a .071 and a .073 gas port.

Keep in mind that felt recoil is a sum of parts and not just a gas port size. So, barrel length and profile, gas port, BCG efficiency, gas tube interface, buffer system, and overall weight of the rifle.

This is M4C.

A good portion of the crowd demands that their gun run with PMC Bronze, A5H4, Sprinco Green or Geissele Super42.

And then complain about the barrel being overgassed.

Well no shit.

Fix it till it won’t run. I’d bet this is how we ended up with reamed out ports.

I agree to an extent. But, one could at that point argue there's not a discernible difference between .073 and .076, but we know that there's a big difference in felt recoil and gun operating characteristics going from .076 to .071 at the midlength gas port position, or at least that I've been able to notice.
