Got to shoot the Gemtec Sandstorm on Pappabear’s 10.3 Colt upper today. It’s interesting how a large volume can with a 30 cal bore really minimizes overgassing.
Interesting that a 10.3" with a Sandstorm is about the same length as a suppressed 16".
How did it sound?
How much does that can weigh? (I mean how does it “feel”, I can look up the specs myself)
How did you mount it? Isn’t it threaded 5/8x24?
What BCGs are you guys running?
Why do you have a fireplace in AZ?
Good work! Thing looks massive, but at 17oz, I can relate to the weight with the M4-2000 on a 10.X barreled rifle. That ACS stock I bet helps make that more balanced. I use a UBR on my 10.x with M4-2000. 500 with irons on that thing is nothing short of what I would expect you two to accomplish. Love when the shorties get out there and touch 500+. Also, thanks for the new 77gr tipped match king performance update on the other thread.
I run a YHM Phantom 30cal on a 9" AAC 300BLK and love the way it looks, handles and performs. Fantastic system IMO.
Pictured at the top:
The shocker was the lack of over gassed symptoms. No violent 1 o’clock ejection of brass, no loud ejection port snap in your right ear, etc. And it’s not loud at all to the shooter.
Must be that specific model suppressor. And we all know how much you love Gemtech, markm. 
My saker 762 still pushes ejection forward and a little gas in my face with 5.56 despite it being pretty large. Haven’t noticed much of an ejection port snap, though.
I’ve only ever noticed gas on my face once with my SDN6 on my a 10.5" 5.56 SBR, and that was while shooting in the rain.
I definitely get gas on my fingers though.
I have to give Gemtech credit. This can went back and they didn’t give Pappabear the runaround. It’s a completely “rebuilt” can and the runout is gone.
