Here come the Jackals
Palmetto State Armory has been moving ahead with its neat JAKL long-stroke gas piston systems and had several concept guns on display at SHOT Show. While they aren’t in production, it is nice to see they are thinking with broad strokes and, like concept cars, they give a glimpse of what the company may start making in the future, especially if they get a lot of feedback.
Among the concept uppers they had were a 9mm ARV that fits standard lowers, a JAKL KS47 in 7.62×39 that fits KS47 lowers and takes AK style mags, and a 13.7-inch 5.56 that fits standard AR-15 lowers and allows for a folding stock.
Good to see there is some innovation out there.

where do they put the buffer tube?
gas piston action (like M1/M14/AK) rather than direct gas impingement so no recoil buffer system is needed.
