Sorry if this has been answered before.  I ordered a pre ban 14.5" M4 upper a couple of days before the AWB expired from BM without giving much thought to the barrel length.  Is the 14.5" barrel now legal?

If you pay big brother $200 and fill out a Form 1 it is. Otherwise you'll need to solder a long enough FS.

Only legal if its a registered SBR, machinegun or you permanetly attached a FS that'll bring the barrel out to 16" or longer.

no

14.5 in bbl MUST have a a FH or MB PERMANTANTLY attached to make the bbl a legal 16in; ANY gun bbl less than 16in mush be regesterd as an SBR

Thanks for the info.  I just took the FS off of my new upper. It threaded off easily.  I also ordered a phantom FS from BM.  I thought I had read a long time ago, about people perminently attaching Muzzle Brakes w/ loctite.  Would a product like JB weld or something similar be acceptable for attaching the new FS when it comes in?

No



I don't see why JB weld wouldn't be acceptable.  It's more permanent than soldering it on.

It all has to do with melting temperature. I believe JB Weld Quick melts at 300F and JB Weld Automotive/Industrial melts at 572F. The alphabet boys stipulate 1100F as required melting point of the solder.
