I'm building a .300BLK with an 8.5 inch barrel and am looking at running a 9 inch hand guard. I have been looking at muzzle devices like the Noveske KX3 that are solid and won't allow gas to be dispursed before the end of the device, as it will be starting inside the handguard for at least half an inch. Does anyone have any other suggestions and dealers that might be carrying them? Thanks!
