[QUOTE="cohunt, post: 1929880, member: 94491"] yikes!!! the gas pressure is primarily based off of gas port location and port size, but back pressure from the suppressor adds to it also. a 10" barrel can not have anything longer than a carbine gas system and it may actually have a pistol gas system--both of which have much higher gas pressures than a midlength gas system (which I would assume that your 16" barrel had--but it may have had a carbine gas system) -- see my pic below (it is for 223, but it gives you an idea of pressures vs gas length/port location) -- if you compare a mid length to a carbine, the carbine has 1.25x the pressure at the port, and a pistol gas has 1.82x the pressure at the port vs the mid-length system-- adding a suppressor is just like adding a muffler to a car, you produce back pressure but you will also notice that the longer the barrel, the less the muzzle pressure --thus you would have a reduction in back pressure form the suppressor if you went longer, or an increase in back pressure with a suppressor for shorter length barrels buy an adjustable gas block, and double check with your suppressor manufacture to see if it is rated for a 10" Grendel barrel if you like shorter barrels, the best compromise is an 11.5 or 12" barrel with a midlength gas system for both the 6.5G and 6.8spc2 -- the 12" will still give you good muzzle velocities for clean kills but stay short enough to be handy in tight brush [ATTACH type="full" alt="Screenshot_20180130-140407.png"]200423[/ATTACH] [/QUOTE]
