It might reset better with a good cleaning but it's clear from looking in there that a shim will help keep that spring located properly.

Good to know. I didn't mess with it any further that day. If l still have the issue once l finish putting it all back together I'll give them a call next week. Thanks for letting me know.

So I put everything back together the other day and the trigger is now resetting again correctly. I think it was because it was so dirty inside and the fact that the hammer spring leg slipped out and was no longer under the HBI trigger spring. I will hold off on contacting HBI for that shim as it seems to be fine without it.

I purchased the MP5 stock and adapter from HBI, now just waiting on my paperwork to put it together. I wonder if it would be possible to make the Scorpion look more like an MP5? Maybe a tapered handguard?

The HBI adapter has excellent build quality and looks like it belongs on the Scorpion.  I highly recommend any and all HBI products based on my experience so far.

Not sure if this belongs in here

Scorpion 3 Plus (not micro) pistol to SBR conversion
7.5" barrel
(heavy) Shroud removed - replaced with A2 flash hider for now
HBI Trigger parts
HBI charging handle
HBI MP-5 stock

Considering:
Getting the 5.3" barrel and shorter aluminum handguard from HBI. Because nothing says sanity like doubling the price of your "investment" in a gun haha.

Two questions and sorry if they've been asked and answered.  

1.  Do the new OEM handguards fit the Gen 1?  
2.  Does anyone know where to get the current gen OEM handguard?

Does anyone have a source on magazine springs?   I would like to replace a fee but CZ doesn't seem to list the springs anymore...

Honestly mags are cheap enough for them, I'd just toss and buy new ones

FWIW
20rounders use the same spring of the 30s.

As mentioned above Evo mags are usually cheap.. You can usually find 20rounder even cheaper than 30 and remove the springs

Okay I am wondering if the polymer HBI Pakse Sapper 6.4″ MLOK Handguard is good or if I should go with an Aluminum set of handguards.  Currently I still have the original version on my gun but I just upgraded it with a Timney V2 trigger, Reptilia LINK™ FOR CZ® SCORPION EVO W/ MAGPUL® ZHUKOV STOCK, Magpul magazine release, Plan B Rearden R2S, and I am debating on doing a 2.26 Unity with a T1 in there or a 1.7 mount that I have on hand.  I also have an AEMs but I find the AEMS blurry with my astigmatism compared to a T1/T2, Romeo 4/5, Comp M4, or a Primary arms GLX MD-21.

I am also looking at sights, Would a 2.26 mount work with this because when I was using a UMP40 having the reddot at 1.93 was optimal because it was not the same as for a M4, or is it a low mount or 1.57 mount better?  I really like the Irons and was using those when I did not have decent red dot.

I am repurposing my Steiner MOR IR for the gun.  I was wondering if I was going to use it again.

Thanks.

I would not recommend the Paske, seen a number of issues with the charging handle channels being a bit too tight.

Go with a good aluminum forend, we are pretty much out of the EVO forend game, but I can recommend the ones from HB Industries- they make good stuff.

My suppressor is a B&T verse 36 (in short config at 5.1 inches.  and 1.7 diameter.  Is the 8.3 HBI good or should I just stick with the standard 6.8 version?

I have a Pakse sapper on my S1, but I want to just go back to the oem handguard for the original look.  What all do I need to do to revert it?  I vaguely recall a barrel nut with an insane amount of loctite that doesn't get used with the Pakse, but I'm not totally sure.

I did the same.
All you need is to unscrew the barrel nut replace the hg and reinstall the nut

I recently took the Scorpion to the range, and after about 20 shots the trigger wouldn't reset. If I put it on "safe" and then back to "fire", the trigger would reset and I could fire one shot. It's the HBI trigger upgrade.

The nuclear option would be to buy the full Timney trigger but I'm not sure I want to go that route.

Well that was easier than I remember. I just used a wrench and cranked the barrel nut on, but the angled front makes it hard to get purchase. Hopefully it doesn’t back off under fire.

Weird you posted that

Mine did the same thing weekend or two ago.

Hbi kit

It seems if I feather the reset it didn't reset
If I "flicked" my finger off it reset fine.
Tried oiling it to no avail.
Ain't had time to fiddle with it yet

Been a while since I had my Scorp.

I fitted a CZcustoms trigger pack and a HBI flat trigger shoe together. I remember having to clearance a tiny bit of plastic out of the trigger pocket/hole to cure the reset problem. It rubbed on the shoe ever so slightly. Mine had the welded screw trigger pack(world edition?)

Maybe worth a look.

I did a TNVC Night Fighter 101 with my 16" during
the window of the braces being on the outs.

I just wanted a night rep with a sub gun.

It was flawless.
