Slaughter I didn't get your e-mail
I don't know why?
As for fitting over a shaved carbine gas block, I have no idea what that even is. Isn't that a free floating system? If it's a free float system with no front bandguard cap, then no. This thing screws securly into the handguard cap. Can you point me in the direction of one so I can do a little research?
As for where I am in NC... I'm in Ft. Hood, TX. Active duty army.
