Anyone use one of these? I like to keep my nose on the charging handle but when suppressed I cant do it unless I'm wearing Pyramex goggles.

I rarely if ever use the forward assist so I dont think I would miss it and in theory I would think it would vent off the excess gas easily as that would be the path of least resistance.

Nobody???? Maybe I'll have to get one and try for myself.

I have one on my 300BLK SBR with Sig SRD 762 QD can. It may help a little, but the can is going to push gas stuff back into the chamber regardless. Now, I tend to run my AR wetter too, so that probably doesnt help. I have gone 300rounds suppressed and it was still running, but dirty .
My Piston SBR from PWS was dirty, but not nearly as much soot at same amount of rounds.
I do think 300BLK runs dirtier due to powder type, from what I have read.
Any slow mo video will show gas coming into chamber with can is going to happen regardless of the vent at the back.
Just my opinion. There are many other people here with vastly more knowledge.
Now, my Sig 516 with can, with 62 grain green tips without a vent and using same can is by far cleaner than the other 2 DI guns. Not sure if its piston design or barrel length, 16 vise 9 and 8.5, or what.. Its just runs cleaner.

Wouldn't the ejection port be the path of least resistance--even
with that device installed?

You would think but I still get a lot of gas through the charging handle. Enough that you cannot put your nose on the charging handle without goggle type eye pro.

I mentioned that SuperlativeArms gas block above. That eliminated all the over gassing I had going on. Think Iím on the 3rd setting. All the remaining gas is bled-off towards the muzzle of the weapon.

I can run any ammo, even lower pressure reloads loaded with frangible bullets (awesome for close in steel-targets).

Looked this thread up again because Iíve been reading and noticed a few of the units are getting away from suppressor use. Something to that, or am I just noticing things?

Ah so...I'm a fan of the nose-charging handle technique too.

How about removing the forward assist assy, and seeing if that
improves the situation? Just as a sort of proof of concept, for the
device.

If no FA doesn't help, the device won't do any better, I'd figure.
