Didn't know about the enhanced bolt. Wonder if it is worth it to soften the recoil from the heavy machine gun bolt it comes with. MPX is much softer push than my Evo or Evo 3+. Otherwise pretty happy with both.
This is from the Nexus site....
"When designing the Enhanced Bolt, we tackled the biggest issue with the OEM bolt: soft material causing excessive wear on the bottom of the bolt. Due to the soft material, a burr will eventually peen over the striker block hole keeping the striker block depressed, increasing the risk of out of battery detonation (OOBD). Our manufacturing and engineering team tackled this issue by producing our Enhanced Bolt from D2 Tool Steel, and heat treating to a minimum of 58 HRC (OEM is 43 HRC). During manufacturing, we chamfer and add radiuses to multiple edges to prevent excessive wear on the hammer and bolt during hammer reset. Using this material, manufacturing processes, and rockwell provides not only superior wear resistance than other bolts for the CZ Scorpion, but also provides far superior impact resistance. We then use a Nickel Boron coating on each Enhanced Bolt to provide additional durability, this Nickel Boron coating adds an approximate 70 HRC to the surface of the bolt. In additional to increasing the hardness of the bolt, the Nickel Boron coating is also extremely lubricious, requiring almost zero maintenance and makes the bolt easy to clean."

Nexus enhanced bolt is legit, pricey but long term practical. OEM bolt on my 3S1 carbine had quite the indented groove formed after 3000 rounds, thought that was normal wear and tear at first but it kept growing. I had a CZ Custom trigger pack installed after 1000 rounds, concerned that was the issue. Leaned if progressed then I’d have an hazardous problem. After conversing with Nexus, I bit the bullet. About 2000 rounds since, no groove on Nexus Enhanced Bolt, only minor scuff marks. If CZ hasn’t changed their recipe on OEM Scorpion bolts, you made the right call. Enjoy
I'm thinking about that trigger pack as well.
Did you get it directly from CZ? I see another one made by Ascalon Arms, the "Ergon EVO trigger pack V2.0" Not sure if they are the same.
Can you give me your thoughts on it?

Yes, I purchased the trigger pack directly from CZ Custom. I mailed in the trigger housing and they installed the upgraded pack for another $100 or so. Quick turnaround if I recall, but it has been a few years. Huge upgrade, with reset and pull, very noticeable from the stock trigger. California ranges do not let you enjoy to the fullest, but during training sessions or on private land, it shoots fast and well. Fun AF. And safe considering the alternative. Again, I am not up to date if the 3+ have the same bolt problem. If you already ordered a Nexus then it must be.
I have heard of the Ascalon Arms trigger pack but am not familiar. It is not the same as the CZ Custom, but trigger pack portion looks similar with metal parts. I just read that it is for the 3 & 3+, whereas the CZ Custom trigger pack is listed for 3 (but I would call /email them to inquire). Ascalon includes some nice features and you get a whole new housing unit, plug and play style it appears. Nice to have a spare trigger housing. Only a 2# trigger, which which is lighter than CZ Custom (4'ish). Personal preference there. The safety levers look well engineered and smooth. I rock the PMM AK style levers, ambi and love it. Works well with the wonderful fin grip.
Since you have the 3+, Ascalon might be your route. It is worth looking into CZC though, I can speak for them.
I ended up going with a Timney trigger. Great upgrade over factory!
Only had this thing a few weeks and the upgrades are as follows...
Timney trigger
Holsun HE515GM on a 1.93" Arisaka riser
HBI pro stock (L) charging handle
Strike industries extended safety lever
Nexus complete enhanced bolt
Ascalon arms receiver shim
Streamlight Pro Tac flashlight
WPS adjustable sling
I also purchased the HBI extended mag release, but it looks like it may already have the Magpul one installed which makes sense since it's a Magpul edition Scorpion.
