Just kidding. That looks great and is an excellent solution for a problem where one of the few solutions is the dorky Surefire offset bezel extension (yes, yes, I know you can use the SF 328/628 head or a Malkoff but they still rub against the suppressor). And while I prefer the classic HK handguard, your setup looks great. Bravo OP!
