Suppressors Suppressor over pressure?
- Thread starter Scubamax
- Start date
Rifle was cleaned hours before these shots. Semi auto ar10. Barnes ttsx factory loads. Dead air sandman. I didn’t notice where cases flew. I was in a box blind. I plan to go to the range soonish.... i have an adjustable gas block. First can on semi auto.
No problem, semi autos and suppressors can be tricky. Adjust your gas block until the ejection pattern is at 3-4 o’clock and watch for pressure signs. If it groups, ejects at 3-4 consistently with none of the usual pressure indicators on the brass you should be fine.
Gas blowback will dirty the brass, esp if the can itself generates lots of back pressure (most do but KAC and SF manage back pressure well at the cost of overall sound suppression)

My rugged surge does that on my 14.5 urgi build with an adjustable block tuned without the can so it's a little gassy
Fire a round from a bolt gun and quickly chamber the next round, let it sit. It will look similar.
