Another 300blk. I'm going with either 8" or 7.5 on my next SBR and thought I'd ask you folks. Here's a pic with a delrin model of my QA/QD muzzle device. The barrel in the picture is 8".

What I'm thinking is if I go to 7.5 inches that should just tuck the shoulder of the muzzle device under the handguard and allow for clearance of the top port. I have plenty of clearance for the silencer to fit under the handguard so that's not an issue. What do ya'll think; go with 8 inches, or 7.5?
