The Palmetto State Armory (PSA) JAKL has been a few years in the making, but itโs finally finding its groove with gun enthusiasts. Billed as a โtruck gunโ since its inception, the JAKL isnโt just another AR-15 clone. Itโs a long-stroke piston-operated rifle that blends classic AR functionality with a fresh approach. Yes, it had a rocky startโQC hiccups, parts compatibility issuesโbut PSA has ironed out the wrinkles, and the JAKL is now living up to its promise with multiple calibers and barrel lengths.
Before we dive into how it performs, letโs set the stage. PSA didnโt send me a complete rifleโjust the upper and parts to convert a mil-spec lower to JAKL specifications. So, how does this system stack up? Spoiler: Itโs unique, functional, and yes, it delivers.
The AR-15โs direct impingement (DI) gas system has long been criticized for its tendency to gunk up the action with carbon, especially under heavy use. Enter the piston system. This isnโt a new ideaโmany companies have tried retrofits or standalone designsโbut the JAKL takes it to another level.
The long-stroke piston design eliminates the need for a buffer tube, opening the door to folding stocks, braces, or even no stock at all. You can fire the JAKL in any of these configurations, making it highly versatile for tactical or compact applications.
A standout feature is the forward, non-reciprocating charging handle, reminiscent of an MP5 (sans the HK slap). Itโs reversible, so lefties can rejoiceโor switch it up just to feel fancy. Converting your mil-spec lower is a breeze, too. A bolt catch swap and PSAโs custom buttcap with a 1913 Picatinny rail are all you need to get rolling. Assembly takes minutes, and the result is a rifle that feels solid and ready for anything.
PSA first teased the JAKL at SHOT Show in 2020, where it turned heads with its monolithic upper and promise of a piston system free from the bolt shear and carrier tilt issues that plagued similar designs. Expectations were high, but early models had teething issues, particularly with gas system reliability and accuracy when suppressed.
Fast forward to today, and those problems seem to be resolved. I ran the JAKL through its paces with six types of ammo ranging from 90-grain supersonics to 220-grain subsonics. Suppressed and unsuppressed, it performed admirably, favoring Barnes 110-grain T-TSX rounds (my go-to for hunting and home defense).
Groups averaged between 1 MOA and 3 MOA, depending on the ammo. Interestingly, suppressed groups were consistently tighterโmirroring my experience with most AR platforms. The only standout underperformer was Federal Fusion 150-grain rounds, but thatโs par for the course when experimenting with different loads.
One of the JAKLโs defining features is its adjustable gas block. With six positions, itโs easy to tune the rifle to your ammo and suppressor setup. The adjustment knob sticks out just enough for quick changes without needing tools. Whether youโre running supersonic loads or subsonics with a can, dialing in the gas ensures smooth, reliable cycling.
During testing, I found it essential to match the gas setting to the ammo. For example, Federal Power Shok 120-grain needed one setting, while Barnes 110-grain performed better with another. Erring on the side of a more open setting avoids short-stroking but beware of overgassingโitโs all about finding that sweet spot.
Letโs talk balance. The JAKL has a monolithic upper, and when you add a suppressor, the front-heavy nature becomes noticeable. Surprisingly, this wasnโt a major issue during range sessions or CQB drills. The weight distribution, while apparent when carrying the rifle for long periods, is less noticeable during shooting.
If the front-heaviness bothers you, a heavier stock or brace could help balance things out. For me, a sling works just fine for hikes or extended carry. At the range, I found the JAKL comfortable and stable whether shooting from a bench, a tripod, or on the move.
One of the JAKLโs best features is its recoil impulse. Compared to short-barreled ARs chambered in .300 Blackout, the JAKL is noticeably softer. The slower-moving, heavier bolt carrier reduces felt recoil compared to the sharp snap of a DI system with a lightweight bolt carrier group.
After running dozens of guns in .300 Blackout, from 4.75-inch barrels to 16-inch setups, the JAKL stands out. It beats my Noveske Ghetto Blaster in recoil management, making follow-up shots faster and more accurate.
The JAKLโs monolithic upper contributes to its rock-solid feel. This isnโt a gun that rattles or feels slapped together. The integrated design ensures rigidity, which likely plays a role in its consistent performance and durability.
The only minor gripe I have is cosmetic. The charging handle occasionally slams forward hard enough to leave marks in its channel. Itโs purely an aesthetic issue, but if youโre the type to baby your firearms, itโs worth noting.
Nearly every round Iโve put through the JAKL has been suppressed, and the results are impressive. The piston system keeps carbon buildup to a minimum compared to DI rifles, even under the added backpressure of a suppressor. The receiver stays relatively clean, and the initial lube I applied has held up remarkably well.
The suppressor also plays nicely with the JAKLโs gas system. Unlike early models, my rifle showed no significant drop in accuracy with a can attached. In fact, suppressed groups were slightly tighter, reaffirming the JAKLโs potential as a suppressor host.
No gun is perfect, and the JAKL has its quirks. First, itโs heavy, especially with a suppressor. While manageable, the weight might be a dealbreaker for some.
Second, aftermarket options are limited. The handguard, in particular, isnโt easily swapped out. While PSAโs stock handguard is functional, itโs a missed opportunity for customization. A magnesium forend could shave some weight, but for now, youโre stuck with what PSA offers.
After spending considerable time with the PSA JAKL, I can confidently say it delivers on its promises. Itโs reliable, versatile, and uniqueโa welcome departure from cookie-cutter ARs.
The long-stroke piston system, adjustable gas block, and monolithic upper set it apart, while the forward charging handle adds a touch of MP5-style flair. Sure, itโs heavy and limited in customization, but those are minor trade-offs for a rifle that shoots this well.
At its core, the JAKL is a purpose-built truck gun that excels in versatility and durability. Whether youโre hunting, plinking, or running drills, this rifle can handle it all. PSA took their time getting it right, and it shows.
Bottom line? The JAKL isnโt just a gunโitโs a statement. And for those willing to embrace its quirks, itโs one heck of a ride.
