I hate to keep beating a dead horse, but did you ever actually get a patent? Or is it still pending?

Had the provisional!!!!!

Applied for utility, that means its covered period!!!

The actual number will be asigned At USPTOs leasure, unless i want to spend 5 grand to expidite it.


Its PASSED pending!!! its a done deal

How about the upper receiver, did that die or is it still in development?

I made a few, but went with the  TAC-12a1 receiver set, it tears down with pins like it should.

No more taking the stock off to tear down,  floating barrel, the handguard is on the upper not on the barrel nut.
