Details

Bring active reset to your PSA JAKL-15. This fully machined Slip Trip Kit is the missing link between your JAKL and a Hoffman Super Safety or AS Designs ARC-Fire V2: one kit, both 5.56/.223 and 300 Blackout, no printed parts anywhere.

What’s in the kit

JAKL-15 Trip: 7075-T6 aluminum, hardcoat black anodized
JAKL Rear Takedown Lug Block: 4140 steel, heat treated, black oxide
(4x) 8-32 x 3/8″ Torx screws

This kit is an add-on, not a trigger. You will also need a standard AR Super Safety kit (trigger, cam, lever, detent) or an ARC-Fire kit; those parts install as normal. See the Hoffman Super Safety S7 curved, S7 flat or the ARC-Fire V2.

Compatibility

Fits	PSA JAKL-15, 5.56/.223 and 300 BLK (one kit fits both)
Built for	“Gen 2” JAKL-15 (see the Gen 1 note below)
Does not fit	JAKL-9, JAKL .308 or any other JAKL version
Reset systems tested	Super Safety, ARC-Fire, Dairyland Defender; customers report success with DTT and the Atrius Super Selektor (not guaranteed with every reset system)

Gen 1 JAKL-15 owners: the Gen 1 uses a flat bolt face that will damage the Slip Trip. You can still run this kit, but the bolt face needs two small chamfer cuts at the bottom first. AS Designs provides pictures and a jig file, and Desk Pop’s YouTube walkthrough covers the process. If you are not sure which gen you have, ask us before ordering.

Read before ordering: installation is not trivial. PSA installs the factory rear lug screws with red Loctite and high torque. Removal can require serious heat and in some cases drilling the screws out; difficulty varies upper to upper, and AS Designs is not responsible for damage to your JAKL. We strongly recommend a licensed gunsmith for the Rear Takedown Lug Block. If you are not comfortable with that risk, this is not the kit for you.

13.7″ and 14.5″ 5.56 upper note: a PSA production change widened part of the bolt about 0.2 mm on these uppers, which can cause the trip to bind. Fix: a hand-filed chamfer on those rails, 1.5–2 mm wide at roughly 45°; no precision machining needed. A hammer spring is roughly 1 mm in diameter if you don’t have calipers.

Anti-walk pins (not anti-rotation) strongly recommended in all AR-style lowers. Armaspec anti-walk pins.

Why the JAKL deserves this

The JAKL-15 is one of the most popular piston guns PSA has ever shipped, and until now running a reset system in one meant improvising. This kit is machined for the platform: the trip in aircraft-grade 7075-T6, the lug block in heat-treated 4140, engineered by AS Designs, the same maker behind the ARC-Fire V2 and the MP5 complete lowers.
