Wanting
RevanAvarice@reddit (OP)
PSA's prices are quite friendly. I think the only component I spent exorbitantly on would be the Reap Weaponries The Scy kit itself.
From PSA's site, you can get SB's FS1913 folding picatinny brace; you wouldn't need an adapter since the JAKL has a built-in real rail, yay. 160 bucks, a lot cheaper than the 420+ Reap charges. Could be a viable interim solution until funds/clarity come up to go Scy, A3 Triad, or remain conventional.
Adapting .300 AAC Blackout did require me to stick to online bulk ammo retailers, using an aggregator like ammoseek.com to both target prices and load specific. For example, I currently favor 110gr HPs, so I got them from RUAG. Not the best ballistics as compared to Hornady Black (that have that aerodynamic insert tip), but a hell of a lot cheaper. I'm running numbers against 55gr 5.56 M193, and of course its slower, but I like the wind drift resistance of the RUAG 110gr comparatively, as to me, that also defines effective range. My BDC has holds for up to 600yds, but I really want to verify at 200/300yds next range visit, and then keep pushing it from there until I hit my ceiling with this combination.

CompulsarEEEE. IS super nice, especially if you get sum performance, definitely.

Saw the Reap guys at GOALS in August, and it makes me glad to see one of their kits in the wild. Really cool stuff

I was really pleased by the build quality. Minimal bulk, and time will tell if their bolts hold up; we made sure to tighten to torque and stop in order to not risk stripping. The contours are nice; as I said to another commenter, I may start practicing using the support hand to hold the weapon at that angled swell right before the magazine; it gets it away from the small real estate in front of the trigger guard and places support underneath where the bulk of the system's mass is.

Oh yeah, I didn't even register that. You've got a pistol length; not much space for your other hand.

if you got the disposable dough, the A3 triad is everything I wanted out of the jakl bull pup. the trigger is actually decent
RevanAvarice@reddit (OP)
I did look at the A3 and its accessories prior to committing to the SCY. If you look at the height of my optic risers; I could probably benefit from purchasing the A3 Riser Handles and installing those.
However, I think the key point was that with the A3 Triad kit, it had its own endplate, and I wanted to keep the receiver of the JAKL the rearmost feature (the Lower comes default with that picatinny system), so as to not modify the weapon in a manner where AFT can claim I manufactured a Stock. Likewise, the A3 pistol config would have not only extended length, but also terminated in a small surface area (the sling mount). Had I opted for the SBR route, the rifle version would have been lovely as their kit does appear to be more robust and compact.
I'm just a short feller with a broad chest and shorter arms, so I actually can weld onto my bullpupped JAKL-SCY combo smoothly.
Drawing another comparison to S&TInc's BPK-762 kit for the Draco, where the trigger linkage was a single bar bent dogleg several times, the transfer system for the JAKL was a much better solution. In dry fire situations, the reset may not be strong enough to be able to manipulate the front safety (there are two now), but in actual firing, the reset is strong.
I forgot to mention that because I had trigger woes on my previous Draco Bullpup project, I already knew to go aftermarket on the JAKL trigger and installed a LaRue MBT-2S. I'll have to get some range time in with someone else's A3 Triad to see what I'm missing out on.

What a beaut

You're a Beaut!

My Jakls are so front end heavy, I feel like this would fix that problem. Is it comfortable to shoot with no buttpad?
RevanAvarice@reddit (OP)
It's controllable without a buttpad.
Do about 200rds, you may have a tender spot in the evening, and honestly, I do think that its the installed sling QD that was digging into me. I was slick that day at the range. With a plate carrier, I would've been unmarked.
Because I shoot it left handed, it really brings you close to the ejection port, so I'm very rigid/rehearsed in firing posture. From the right hand position, wee, any hold goes wee!
The weapon absolutely balances to the rear in this bullpup handgun configuration. As you bring the weapon up, it will definitely bias towards your chest/armor.
My posture is as follows: Firing hand does apply a slight push forward, nothing exaggerated. Likewise, the supporting hand (which has very little safe real estate up front), is pulling back.
In the future, I may train a way where I place my supporting hand around the angled housing in front of the magazine (improvised angled grip), and perhaps that would balance better, but is going to be a manual of arms unique to this setup.

Damn this goes HARD.
Reminds me of ghost in the shell.

Future trip to the range is to look for a 200-300yd lane.
That, or I wait till I go varminting/culling again and use a rangefinder to define the killzone.
Thus far, its confirmed at 100yds, 110gr is still stabilized at that range. Magnification helps. With the optic setup I go from 3x to 6x.
My experience with ACOG and MGO has been preference towards 3-4x, using holdovers and BDC reticles. 6x is a bit of an adjustment for me, because I am losing FOV that I took for granted.

Writeup:
PSA JAKL chambered in .300 AAC Blackout, 8.5" Barrel
Reap Weaponries The Scy
Are the core of the weapon system, I'm pleased enough with the optic choice:
Primary Arms SLx 3X MicroPrism™ Scope - Green Illuminated ACSS Raptor Reticle - 7.62x39 / .300 BLK
...that I am going to retain it. The Monstrum front-magnifier is a fun gimmick that can come and go. I've zeroed both at 50yds, and zeroing a front-magnifier was a counterintuitive process, but I got thru it. Optic height is an unfortunately necessity; I wanted to minimize the amount of stacking mounts/adapters, and I align just fine as currently configured.
The height over bore is insane, thankfully, the recoil is tamed by a Sharps Badlands muzzle device, a necessity so that I can avoid the muzzle blast. Also, adjustable has is nice in taming the recoil some. Me and my gunsmith had fun on the initial takedown of the firearm, and it was interesting to see the recoil system and its similarities to what SIG did. They would give the edge to the SIG.
Current load is RUAG 110gr, and it serves fine. I did initial alignments at 10/25yds, zeroed at 50yds, proofed at 100yds, and I didn't see keyholing. Now I just gotta take it to a facility that has 200-300yd features. The alternative has been just going out with a rangefinder, indexing those distances, and taking hog/coyote at that defined zone like I did when I bullpupped my Draco using S&TInc's kit.
I'm happy enough to keep it in this weird handgun configuration. As is, it fits into my smaller backpacks in its own compartments with its magazine pouches molle'd in next to it with its ready mags (stowed with a 20rd, accompanied by 6x30rd) Even smaller than the aforementioned Draco Bullpup.
As silly as angled irons are: I fire this weapon from the left-hand weapon. Its actually a nice nose guide like I would have with a charging handle on an AR. It was really key that I tuned the gas, as when this thing extracts/ejects, that brass can fly real close to my face, and yeah, I had to carefully rehearse my alignment until I got familiarized and comfortable that every time I come into alignment, that I am not going to eat hot brass right outta the pipe.
200rds thru, no stoppages (that were not related to tuning the gas system).
Currently, it serves as my Truck Gun, or should I say my backup handgun (because it doesn't stay in the Truck overnight and I bring it in with me to store at work).
I took a lot of experience from when I bullpupped a Draco. This Reap Weaponries kit I would say is a more precise fitment than S&TInc's, and less fitting was required. I really like how its not just mounted with the front receiver pin, the pistol grip bolt, but also two further pins forward on an mlok-adapter to the JAKL handguard. Snug as a bug.
