SIG Rattlr vs Palmetto State Armory JAKL with "Coch"
This video compares the SIG Rattler and the Palmetto State Armory JAKL, both chambered in 5.56 NATO and configured as pistol uppers for AR-15 lowers. The SIG Rattler features a 5.5-inch barrel and a non-removable flash hider, producing significant muzzle flash and sound. The PSA JAKL, with a longer barrel, allows for interchangeable muzzle devices and utilizes an AK-style long-stroke operating system with a non-reciprocating charging handle. Both platforms offer adjustable gas systems and folding braces, making them compact and fun for various roles like truck guns or range toys, though the Rattler is noted for its extreme muzzle blast.
