M11/15 Gas block testing

[vertex]

I did some testing with one of my really smart friends who used to sell/make gas blocks and we tested out some combos with his gas block.

He has a gas block system that you can tune to precise sizes to a thousandths of an inch.

Here is unsuppresed with the gas block open to .073

open to .086

suppressed open to .052

suppressed open to .086

Great info Vertex. Thanks a lot for sharing that.

For us old guys that have a hard time seeing the PACT display here's a table.

.073 open 825 RPM
.086 open 910 RPM
.052 suppressed 705 RPM
.086 suppressed 1122 RPM

Very useful and interesting information!
That’s exactly how I keep track of my ROF numbers and which ammo was used.

IRM? Barrel length?

stock IRM just swapped out the gas block.

825 w IRM pretty good. Did it fail to catch the sear at or below .073?

Wouldn’t eject brass.

Looks like it was the Gov'nah...too bad they are not made anymore. Very nice product.

It’s the new limited edition run I’ll be honest, I totally understand why he chose to not deal with it anymore.

It requires some effort and a smarter gun user but damn it’s a badass gas block. I will be using them on all my toys.

Yup, I'm a year late on the Gov'nah bandwagon. If anyone has an extra they are willing to part with let me know. Been looking for months!
