The PSA OLCAN is the JAKL repackaged into a bullpup chassis, and the version we've been shooting is the 14.5" 300 Blackout in FDE with a KeyMo brake pinned and welded out to legal rifle length.
What that buys you is a non-NFA rifle that's about 26 inches long with the same upper that drives the regular JAKL — long-stroke piston, monolithic 6105 receiver, tool-less adjustable gas, knurled side-charging handle.
Why we picked one up
Bullpups have always been interesting to me. For the longest time, I hated the idea of the chamber and the explosion being right near the shooter's face, but with the reliability of modern ammo and almost no issues, that fear/dislike has subsided, and now I can appreciate bullpups more.

I've been through a number of bullpups, like the Keltec RDB and the Tavor X95, so bullpups are nothing new for me, and while I like them, I don't see them as an AR replacement.
Specs at a glance
The OLCAN ships built, but you can order just the lower if you already have the JAKL upper.
There's no separate brace or stock to spec because the bullpup chassis is the stock.
The handguard is part of the upper, the buffer system is fully captured inside the receiver, and the only "shoulder ergonomics" tuning is the polymer cheek riser that bolts to the upper Picatinny rail.
Here's what came in the box.

Addressing the subsonic cycling concern
If you scrolled the PSA product page before you scrolled this review, you've already seen what some owner reviews are saying — that the OLCAN won't reliably cycle subsonic 300 Blackout, even with the gas block opened up and well over a thousand rounds through the rifle.
That deserves a direct answer because the OLCAN's whole reason to exist is suppressed shooting, and the whole reason 300 BLK exists is that it ports subsonic ammo cleanly through a can.
The pattern in those reports isn't lazy testing — owners are saying they tried multiple manufacturers, ran the gas block all the way open, cleaned and lubed everything, and still ended up with the bolt riding over brass or short-cycling more often than not.
Most of them are otherwise positive on the rifle for supersonic loads with or without a can.
These aren't takedowns from people looking to torch the gun on the internet — they're working owners saying the rifle won't reliably do the one thing they bought it for.
I've shot both supers and subs and both cycled fine, I did not adjust the gas and it's wide open. The bolt locked back just fine in both supers and subs.
Worth noting: PSA's own JAKL product copy carries the caveat that they cannot guarantee subsonic cycling with low-back-pressure suppressors.
The OLCAN inherits that JAKL upper, so the caveat carries.
The tool-less adjustable gas helps; it isn't a magic bullet.
Build, fit, and finish
The FDE Cerakote of the upper and the lower match extremely well, PSA has done a good job getting their colors to match across the platform. The bolt also feels buttery smooth on this OLCAN.
The 6105 monolithic upper is the most distinctive piece structurally.
PSA captured the buffer system inside the upper so the bullpup chassis doesn't have to deal with it, and the upper-to-lower fit on ours is tight enough, there's a bit of play but nothing that is above an AR with no tension lower.
The bolt and carrier are the same Carpenter 158 / 4340 hybrid the JAKL has been running since launch.

That's a known-good combo on the platform.
Controls and ergonomics on a bullpup
The OLCAN takes the controls people know from an AR-15 and rearranges them on a chassis where the action sits behind the trigger.
Magazine release
Ambidextrous mag release at the rear of the receiver.
The magazine release takes some getting used to, it's not as natural as other rifle ergonomics and that's not as much a jab at the OLCAN as it is just a reality of the nature and design of bullpup rifles.

Charging handle
The knurled side-charger is the same JAKL part and it's tool-lessly reversible from left to right.

That matters on a bullpup because handing a left-charging rifle to a right-handed shooter on a hot range is a non-starter, and PSA built it to swap without an Allen key.
I'm right handed so I left the charging handle in it's default left configuration as that works best for me as a righty.
Safety
AR-style safety lever and this is probably the most "AR" feeling feature of the OLCAN, it's in roughly the same place and feels nearly the same as any other AR based platform.

Trigger
This is the part of any bullpup review where you have to be honest about what a bullpup trigger is.
The OLCAN's trigger has to send its motion through a mechanical linkage from the grip back to the fire-control group at the rear of the chassis.
That linkage adds length, mush, and a soft break compared to a clean drop-in AR trigger.
It's not PSA's fault.
It's a bullpup tax.
The Tavor X95 has it, the AUG had it worse for years, and the OLCAN sits somewhere in the middle.
Of five pulls I got an average of 7 lbs 8.7 oz, it peaks a little over 8 lbs with a spongy take-up and a soft break.

Aftermarket options for the OLCAN are essentially nonexistent and I wouldn't expect them anytime soon as the gun would need to gain in popularity to justify aftermarket trigger offerings.
Sights and optics readiness
Full-length top Picatinny rail.
No iron sights ship in the box.
The cheek-riser height is the gotcha.
Other owners have flagged this — to get a clean cheek weld with the riser installed, you'll likely need taller cantilever mounts or absolute-cowitness-spec rings.
Most LPVOs sit too low at standard 1.54-inch mount height and show shadowing or a too-high reticle.
The trick that works on a Tavor or AUG works here: pick the mount height around the cheek riser, not around what your AR usually wears.
I threw on a Primary Arms Micro Prism 3x on this on top of a Unity riser to get good eye relief. (Yes, I'm missing a screw, I'm gonna find it somewhere!)
I like this setup as it rises the optic to a more natural line of sight for this gun and I recommend similar for anyone who is considering what to do on their OLCAN.
Recoil and how it shoots
300 Blackout out of a 14.5-inch barrel is mild to begin with, and the OLCAN's piston system plus rear-of-rifle balance keeps it tame.
The mass is over the firing hand, not out front — the bullpup payoff people who've never shot one don't quite believe until they shoot one.
The recoil is honestly slightly less than a normal AR, I think this is likely because your primary point of contact with the system is right in the middle of the gun. Most of your weight is in the rear so muzzle rise might be slightly more because of this but the overall recoil feels pretty soft.
The other side of that coin is gas to the face.
Bullpups put the action close to your eye, and 300 BLK suppressed adds gas.
The piston system reduces blowback compared to a DI gun, and when you throw the silencer on it really doesn't change it much the long stroke pistol system does a good job of keeping gas out of your face. This is one of the biggest positives of the bullpup designs.
Accuracy
We don't have a body of published 300 BLK group data on the OLCAN yet.
The 5.56 OLCAN tested elsewhere shot in the 1.8 to 2.5 MOA range with match ammo at 100 yards, but that's a different upper through a different barrel and shouldn't be quoted as the 300 BLK number.
I show two five-round groups both with subsonic ammo, one is S&B 200 grain subsonic and the other is PSA SABRE 220 grain black tip.




Reliability and round count
Our verdict at 320ish rounds.
The minimum we'll publish a hands-on review at is 200 rounds, and the goal is 500.
We'll update this section at 500.
Have had no failure to feeds or failure to ejects and really no functionality issues at all.
Aftermarket support
Almost nothing exists yet.
The OLCAN is five months old, and what shipped in the box is what you live with — the Die Free Co. Kung Fu grip, the mil-spec safety, the polymer cheek riser, the JAKL knurled charging handle.
If your model is "buy the platform, then upgrade the trigger and the handguard," the OLCAN isn't there yet.
The handguard is integral to the monolithic upper; it isn't replaceable.
The trigger has no drop-in upgrade we'd recommend buying today.
That doesn't mean it'll stay that way.
The JAKL had a thin aftermarket at launch and now has a real one.
The OLCAN will follow that curve.
Price and value
$1,399 street as of the writing of this review.
That's roughly $400 under a Tavor X95 and well under a Q Honey Badger SD, which is the closest 300 BLK can-host comparison and runs around $2,899 MSRP for an SBR with an integral suppressor.
The harder value question is internal to PSA's own catalog.
The same JAKL upper that's on the OLCAN is also sold as a conventional 14.5-inch rifle with an F5 stock at a similar price point.
You're paying for the bullpup chassis, not for the upper.
If you want short OAL without an SBR stamp, the OLCAN earns its money.
If you don't care about OAL, the standard JAKL gives you a cleaner trigger linkage and more aftermarket runway.
How the OLCAN compares
PSA OLCAN vs IWI Tavor X95
The Tavor is the modren bullpup yardstick (the AUG is the OG) and it's about $400 more expensive in 5.56.
The OLCAN gives up nothing major in fit and finish and it ships as a 300 BLK can host out of the box, which the X95 doesn't.
The Tavor wins on aftermarket maturity, on a slightly better factory trigger, and on a longer in-the-wild reliability record.
PSA OLCAN vs the standard PSA JAKL rifle
Same upper, different chassis.
The standard JAKL is a conventional AR layout with an F5 stock at a similar price; you trade the bullpup OAL for a cleaner trigger linkage and a more open aftermarket.
If 26 inches of overall length matters to you for a truck rifle or a suppressed range gun that fits in a backpack, the OLCAN wins.
If it doesn't, the JAKL is the more practical buy.
Who should buy the OLCAN — and who should pass
Buy if: you want a non-NFA 300 BLK can host, and want something unique and fun to take to the range.
Pass if: subsonic-only is your use case, you want a crisp factory trigger, or you're an aftermarket-first buyer who upgrades triggers and handguards on day one.
Final thoughts
Personally I like the OLCAN for what it is, my main drawback is the weight of the OLCAN. It's fun to run around the range and send rounds down range, it's relatively accurate and flat shooting.
If you don't have a JAKL already the OLCAN is a good buy for all the same reasons and you could always inverse the theory, have an AR lower? You can slap the JAKL upper on that and have both options.
