Looks like those that got the Polymer80's from the former sponsor here got lucky also.
Polymer80 PROACTIVELY Stops Selling Polymer 80% Receivers - The Firearm Blog
I was wondering what was going on with him.
Isn't that similar to comments made about Glocks when they first came out? Seems polymer has become common in handguns now, though.
I spoke with Dan Malcolm, from Polymer 80 a few days ago. They had ceased sales due to EP Armory being raided by the BATFE. They are now selling again after clearance from the feds. I had a new shipment of P80's arrive along with a copy of the ATF letter allowing these sales. I would never recommend plum crazy of NFA, not because of any of this but because copying the forged specs and using poly is not a good idea.
