Permanant FH attachment?

I am in the process of buying the components for an M4 build, since I can’t find an LE6920 out there. I want a 14.5" upper and a permanantly attached flash hider to avoid the NFA issues.

Two questions: Is possession of the upper (14.5) w/o the FH attached, and lower at the same time, UNASSEMBLED a no-no?

Can any of you recommend a good gunsmith/armorer in the Dallas area to do the permanant FH attachment work?

Thanks,

Wayne Dobbs

Mail the barrel to ADCO.

Thats hands down the best advise anybody can offer.

Yes if you have the upper and the lower with a short barrel and no stamp that is a big no no.

Adco is a good company to send the upper to.

ADCO has quick turnaround.

Sounds like a consensus to me! Thanks for the help!
