The 7" 6.5 Ultra will create a lot of back pressure and should really be used on bolt guns.
I went with the Ultra 5 30CB because there is more opportunity for the gas to bypass in the larger holes in the baffles, with a shorter baffle stack, and I have seen them run on Grendels already.
The main Grendel I plan to suppress will be 12". I'm going to use an adjustable gas bolt carrier on it.
