Suppressors TBAC Ultra 5 vs 7 Back-pressure

[Commander Shepard]

Between gen 1 Ultra 5 and Ultra 7 in 6.5mm, which can should have less back-pressure on a Seekins SP10? I don't have the ammo to test both.

The Ultra 5. Do get an adjustable gas block to tune the rifle properly.

Yep. I have the 5 on my 6.5CM AR. Not too bad with back pressure. But do use a quality adj gas block to tune.

I tuned it with ultra 7 and then put on the ultra 5. I honestly couldn’t tell a difference between them, the rifle cycled well with both cans once tuned for the 7.

The rifle came with an adjustable gas block so all is well.

You could also get it in 308 for less back pressure in a 6.5
