Seems like every day there is another one  coming out.

plus there are a handful of AR like guns, that are not exactly ARs but but are similar and use some AR parts though not AR receivers exactly.  

If the mond's think its tac worthy I can make somehting up nice?

Okay, this is not an AR15.  It looks a little like one but the manual of arms is different in many respects.  TNW firearms Aero Survival Pistol (ASP)

Another company, Angstut arms, makes a somewhat proprietory 9mm ARish gun.  It uses its own lower, magazine release parts etc.  Not sure if hte upper is propriety or not but i suspect it is.  The manual of arms is exactly the same as an AR15, even locks back empty.  Very sharp looking.  It does use AR15 grip, stock, buffer, RE, FCG & Handguards.

its not cheap.

here is another proprietary glock billet lower, pretty neat has a ergonomic mag well for your hand.  It can use standard AR uppers & 9mm parts.

pictured w/ a quick take down upper/handguard system, I belive by DRT Tactical or something.

Mag tactical Nano 9mm.  

Not a good review, at all
