This one is also has a stock with a Law Tactical folding hinge. The lower appears to be a Sharps Bro "The Jack".
Junior's second AR is another short barrel, possibly 7.5 inches, again with no iron sights with an EOtech and a light attachment and what appears to be a Troy PDW stock.
IWI Galil ACE GAP39SB
The Galil ACE GAP39SB, a civilian "pistol" variant of the ACE series with a stabilizing brace, is used used by Henry in his first fight with Junior.
