Frequently Asked Questions

What makes the PSA JAKL's operating system unique?

The PSA JAKL utilizes a long-stroke piston operating system, unlike the direct impingement system found in many AR-15s. This design contributes to a cleaner action and allows for the use of a folding stock without a traditional buffer tube.

How does the PSA JAKL achieve legal rifle length with a 13.7-inch barrel?

The 13.7-inch barrel on the JAKL is legally considered a rifle by having a muzzle device permanently attached via a pin and weld process. This brings the overall barrel length to the minimum legal requirement of 16 inches.

What are the key features of the F5 'Boot' stock on the JAKL?

The F5 'Boot' stock is designed to fold to the side, offering a compact profile. It also features adjustable length of pull and a slight adjustment for the cheek riser, enhancing shooter ergonomics.

What materials are used in the PSA JAKL's construction?

The PSA JAKL features a barrel made from 4150 Chrome Moly Vanadium steel with a 1:7 twist rate. The bolt is constructed from shot-peened Carpenter 158 steel, and the carrier is made of 4340 Steel.
