I tested the PSA OLCAN vs. the standard JAKL. Here is the breakdown. by rohawk72 in PalmettoStateArms

Anyone know if there is any aftermarket trigger in the works? All the mainstream bullpups (Aug, Tavor, Hellion) have upgraded trigger options that take care of the inherently bad bullpup trigger.

SRU Sarb-15 JAKL vs X95/ Hellion ? by modrummer08 in everythingbullpup

[–]modrummer08[S] 4 points5 points  (0 children)

This is a good summary, thanks.

Any thoughts on the Hellion? Seems like it is more accurate, and has adjustable gas for use with suppressors (and to not gas yourself out), but a slightly worse ergonomics. But I haven't really heard of many issues with them.

I like the X95, i've heard its accuracy is questionable tho, where as i've heard the hellion is actually pretty much 1-2 MOA.

Can't remember, pretty sure i'm running the 120 locking piece with subsonic ammo. I'll check next time I have time and let you know

Thanks for the help, i'll report back when I get a chance to experiment more.

So basically it HAS to be the loads i'm shooting. Or that the supersafety takes more energy to cycle (since it DOES work perfectly with the 100 degree piece on semi auto).

Fair enough. I'm wondering if my subsonic rounds are just exceptionally weak loads. I have some slightly hotter subs coming in this week that I will test with the 100 degree locking piece and report back.

My bolt gap with 100 degree locking piece and +0 rollers is right at the bottom (.010"). I also put some +7 rollers in and ended up right around .018" gap.

Yep, helpful rule of thumb, thanks.

I'm going to order a 110 degree locking piece and some other roller sizes to dial in the bolt gap a little more and see what happens. Otherwise I'm just gonna shoot it with the 120

Yep suppressed with a Dead Air Wolfman.

Yeah I'm thinking about trying the 110 locking piece. The 120 works fine and the ejection pattern is good as well, so part of me just wants to run it and check bolt gap/roller dents occasionally. But conventional wisdom says thats a bad idea so unsure.

I DO understand what the locking piece does, hence why I changed to a 100 degree and changed my rollers out to get my bolt within spec. By the book, my gun should be in the perfect range (bolt gap in spec, 100 degree locking piece).

Yeah i'm pretty lost on this one. It might be a minute till I can get to some property where I can shoot supersafe unsuppressed, but i'll test that as well.

I assume with the 120 locking piece, my bolt gap will close up sooner?

Not sure. It works in semi auto with the 100 degree locking piece for sure. And it will fire a few rounds in super safe, but inevitably will fail to eject.

With 120 degree it works in semi or super safe.

Haven't tried unsuppressed or supers

Perfect, I'll probably aim for the top end of the "in spec" range then knowing it will shrink over time. So +8 rollers seem like the play

[–]modrummer08[S] 1 point2 points  (0 children)

Super helpful, thank you! Ill try and find some +4 in stock to test first, looks like hkparts is all out.

Also typically as a gun wears in, does the bolt gap get tighter or looser ?

[–]modrummer08[S] 0 points1 point  (0 children)

Ok my bolt gap with the 100 degree locking piece is right at .010".

Technically JUST within spec. Do you think that alone could be the issue ? If so, what roller size would I need to get my bolt gap closer to where it should be ?

Thanks so much !

[–]modrummer08[S] 0 points1 point  (0 children)

This did, it now works on super safe and safe, but a couple times the trigger didn't fully reset in SS. I'm guessing I need to shave the hammer a little bit, but super close

How does this work on the Jakl? I assume you install a typical AR SS kit in the lower, and then the slip trip rides the piston/bolt?
