So I'm starting to get serious about building an AR.

 

Looks like I'll be buying a CMMG or Bravo Company mid-length upper to start.

 

If I don't have an AR lower yet (still honoring my commitment to the NJGF Spike's Tactical group buy...), is it ok if I get an upper with "evil" features such as a bayonet lug and flash hider shipped to me? Plan is to dremel the bayo lug off and then send the upper + muzzle brake I'm buying separately to ADCO for them to pin/weld the brake on before I get a lower.

I wouldnt chance it - just get the whole thing drop shipped to Adco he will take the lug off as well.

 

Technically you wouldnt be in possession of a firearm, nor constructively possess an assault weapon since you dont have a lower. However, since adco charges like $15 to remove a lug (check on that amount) why bother since the extra postage for you will break even.

 

Good luck and congrats on your purchase.

 

EDIT- you can also mail your brake to adco separately just let him know you are doing that and include order number with brake.

what NJGF Spike's Tactical group buy??? What did i miss... shit.
