NJ is 6+1 on semis till they fig something else to screw us out of. Effectively, I can float one for 7... FFT makes a full length 5+1 in titanium but not cheap. Other than reduce weight and bring you closer to 922r, it's not worth it because NJ could care less about 922r as far as I can tell. I can get the tube as long as it follows the 6+1.... No cards needed... Appreciate the help... Yes, the crimped limiter looks terrible on such a fine weapon.
As it stands, I want to maintain a Zero Tool policy for the M4 and o far so good in hat dept. I love breaking it down with no tools.
