It’s a long answer so bear with me. Because It’s two fold. A) As I discussed , there is an issue with the striker block not functioning or losing function due to damage incurred from hammer reset and as a result it is possible to have an OOBD detonation prior to the round completely seating into battery. As such, if the striker block isn’t functioning, the hammer can strike the firing pin and there is nothing preventing the pin from hitting the primer and causing ignition before it has completely seated in the chamber. . B) the is also an issue is not so much with the scorpion but direct blow back action itself when firing extremely high pressure (IE: “hot”) ammunition. Unfortunately, as the scorpion is made of polymer, it is MUCH more susceptible to damage vs a steel or aluminum receiver with blow back action. It’s also exacerbated by bolt bounce when the bolt rebounds off the breach face like a basketball hitting the ground. Providing more opportunity for a hot round to back out of the chamber before it has finished detonating… Most blowback platforms like the stribog, AR9 variants, etc , it is unlikely the shooter even knows when it happens unless they examine all the spent casing because of the aluminum receiver, the likelihood of damage is extremely low…not saying it can’t happen, even Glocks have been blown up on occasion. But generally speaking, the problem of hot ammunition in an aluminum receiver is moot. And it’s extremely rare to see it. The scorpion, however, has a polymer clam shell receiver. And being direct blowback with no delay to let higher pressure ammo complete ignition before cycling, it is much more vulnerable to case rupture and getting blown apart. No. As of yet, CZ has not addressed this or remedied it. They’re basically fixing them case by case as they blow up. The only remedy is an aftermarket company called Nexus that has full billet aluminum receiver replacements and tool steel bolts. The receiver works with the OEM bolt and has a delay. Thats most important.

@@theuncouthtruth9551 I sent an email. And I also am waiting for a reply and will send a video of it failing . I want to see if they will replace it as preventable measures with an in spec bolt. What you think? I know you have had contact is that something on your opinion they may consider?

@@chrisdobz4468 yes. Works with all. Even the PSA mags. Even though they may need some fitting on the front of the mag because they stick a little bit.

Ok sweet! I went ahead and ordered a Nexus in FDE and a bunch of Magpul Scorpion mags so I should be good to go. They are just waiting on the triggers to arrive and it’ll ship out.

@@overwatchtactical888 it feels tamed to me. Akin to adding a small comp. That said, I certainly don’t want people to get the impression that it’s gonna be like an MP5 because that’s not the case. But it does feel dampened to me about 20% shooting side by side

@theuncouthtruth9551 I enjoy the shit out of my scorpion. I've added a couple of nexus parts. Hbi. Ect. At this point picking up another part that actually enhances my 9mm is probably worth it. Thanks brother for the input and video

@@videodevil2500 no. The bolts are identical and made of the same material in the 3+

@@Break.theteeth.ofthe.wicked369 honestly, just get the extractor. Literally all you need. I’ve been running this gun for YEARS now. Not even sure when I made this video. But have never had a malfunction. I changed the extractor immediately simply based on reviews of it being an issue but tbh I’m sure it would have been fine even if I didn’t. Just run it as is and buy the cheap extractor when you get aero it. It’s a solid AF gun 💪🏻

@@theuncouthtruth9551 even if I had the money to get more parts to make it better, that's all I would need? I'm using it not for competition but for training and prepping, I'm one of the rapture/apocalypse or war preppers and I wanna make sure i get a good solid gun that I never have to replace with another, and just set my sights on my first ar15, is there really anything to make it better and more for war and rugged uses or is that all just for another gun? If I can, I'll take it and upgrade it and make it my everyday shotgun, home defence, training, war, anything, I'll take the extractor only but if I can for sure make it way better or at least a tiny bit better with smooth shooting and reliability then I'll spend a Lil more, is that all you recommend or is there a Lil extra sum I can add, if not I'll just grab the extractor, a sling and maybe a clamp for the barrel and call it a day, what do you think, idk what you use yours for so I'm letting you determine if my uses are gonna need more or just that one thing, thx for getting back with me tho big dog 💪

​@@theuncouthtruth9551 you should definitely make a video of you shooting it, I'd love to see how your specifically works it looks pretty good

This is absolutely true.

@@markgillis6162 yep. Snaps right on. Perfect fit. Same identical footprint on the rear as the scorpion

@@theuncouthtruth9551 Thank you.

@@yong7801 yes. I will!

@@hunterhiker6101 yes. Every length has been run suppressed. With subsonic ammo too. No reported issues.

Lengths will come in 6.3,8,12,14,5,and 16” lengths. With accommodating handguards from HBI

@@theuncouthtruth9551 sweet! I won't be buying a whole rifle mostly interested in the receiver set!

@@bmartin863 same here. The platform has essentially been reinvented. Not sure how MAC communicates with vendors. Some of them have representation through a firm like leviathan. But that would be something the owner of Nexus would have to do in seeking him out for a review.

@@theuncouthtruth9551 I know he has a @coppercustoms store .

You will be able to purchase everything together as a fully complete firearm, as well as you can purchase everything separately including just the trigger pack and piece everything together directly from the website.

@@gladstoneworrell5147 I’d definitely pull the piston out and check for obstruction on the piston or in the chamber. As well as if it’s in spec. You can pull both out and take calipers to them and measure for matching measurements mine had some weird gunk in it. It wasn’t cosmoline or a burnt O ring. Not sure what it was.

lol. Duly noted 👍🏻

Polished ramps always helps. But even if you remedy the issue of OOBD, there is still the problem of hot ammunition. Meaning even if it seats and performs as function, by nature of a blowback design, it is still vulnerable because its polymer. Nexus will soon be releasing a full billet receiver with Bering delay that will entirely remedy any issue. No matter how hot the ammo is and works with the oem bolt. I’d strongly consider this. It’s the ultimate remedy for the platform. Because even if an OOBD or super hot round sneaks in, it’s a non issue.

@@theuncouthtruth9551 saw them posting about it in the scorpion reddit and cant stop thinking about it lol. been wanting a stribog for the delayed blowback, but with this new upper i dont think i'll be buying one, yet.
