Today I went to my LGS where my Griffin Armament Resistance 9 can is being held in jail, to have a supervised range visit. Initially I shot some Armscor 147 grain subs - first trigger pull - I got what seemed to be a slam fire (2 shots ripped though) then I got a squib load. Also discovered that I had a mild baffle strike. Switched to PMC 115 grain ball - standard velocity. I kept getting FTF every couple rounds, some would have a light primer strikes, some would not. No further baffle strikes; occasionally would get the odd 2-3 round burst. Took suppressor off- and it ran like a champ???? Put suppressor back on - and FTF would ensue. I am thinking that the culprit is the lighter HBI trigger springs - and my gut tells me to switch back to factory springs. As for the subs the LGS dude said that Scorpions dont like 147 grain subs- which I cant quite rationalize, but ok whatever. What am I missing here? The Griffin can is my first suppressor, so knowing that I already out of the gate have had a mild baffle strike, leaves me feeling all sorts of funny inside. Not to mention the introduction or FTF. FWIW - I am using a Griffin Tri Lug system. View Quote I had a 1% FTF rate for the first 1000 rounds. CZ gave me a new extractor, springs, etc. Haven't had any other FTF's since so I'm not sure what that was about. Was shelved as a defense gun until I got it figured out. Not exactly sure what it was but it isn't happening any longer. |

I've had zero fails with my evo.
I run a octane 9hd and hand cast 150 gr lead sized to .355 with 3.2 grns bullseye. No idea what he means by it doesn't like 147 gr. Just blowing smoke up your arse i think. I check all nuns with a mag or two for keyholing then never shoot un suppressed after that. I've not shot in suppressed nor any factory ammo since. So far 100% reliable. How the hell did you get a baffle strike on a new can and new gun? Is the ammo keyholing? Something is rotten in denmark and someone owes you a new can either bad threads, barrel, or ammo. Where you using the factory evo threads or a adapter between it and the can? |

Interesting in regards to extractor and springs. I have not yet been able to get back to the range to test and confirm function with the added spacer, and re-set back to stock springs. Last range visit it appeared to be extracting everything just as it had been for 1000's of rounds previously.
I will keep this in mind if I have further issues, once I confirm function. Id really like to have the HBI trigger spring in there- and maybe that spacer was the main culprit- but for now- Im back at ground zero and will slowly integrate HBI back into the trigger pack |

I ended up buying a black S1. In a couple of weeks, probably, KY Gun will get it to my dealer, then I'll have to wait for the stupid WA "background check" period. Maybe have it in hand by Easter.

Just noticed ETS is making Scorpion Mags;
It has probably been discussed in the thread but I missed it. What is the verdict? |

Almost bought some of those 40rd ETS mags the other day from LGS. Then I saw “used” Glock mags and bought a handful of OEM G19 mags that look brand new instead.

This is probably answered somewhere in the 240 pages, but I'm not finding a definitive answer easily.
Does the SB Tactical folding brace require any other parts or adapters to fit to the pistol? Or is is a complete kit? Talking about the part "SBTEVO" that retails for $199 and sometimes better. I see some places selling their own adapter either with or without the SB brace itself. But is a separate adapter needed, or desirable for some reason? I have and SB folding brace on my Zenith MP5 clone and it works just fine. I might SBR the Scorp eventually, but it would be in line behind a couple other guns, including the Zenith and an Uzi carbine. Thanks Rob |

Got some gen 3 CZ 30 rounders swapped out under warranty by CZ because cracked gen 2 feed lips. Third times the charm? One thing I am sad to report is they haven't beefed up or changed the material that the floor plate is made of. Don't ever drop a CZ Scorpion mag on a hard surface in the cold or loaded. The floor plates split very easily. I'm surprised but having dealt with CZ over the past several years I can tell you it takes them several generations to get it right. Maybe gen 4 mags will have a proper base plate that can take a hit. Got a ton of Magpul 35 round magazines as well. I'd bet $87 dollars the Magpul magazines don't crack when dropped loaded or in the cold.

How hard is it to convert a 7 inch gun to a micro with the K kit from HB industries? I want a very compact gun, so the Micro from CZ does have some appeal as its already built however I don't love the inch shorter barrel vs the HB kit, I know its probably trivial to overall performance but I dont really like the brake on the micro or the fact that the end of the barrel is a inch under the handguard which limits suppressor and muzzle device selection. Or maybe the real answer is stick with 7 inches. The original use case was an HD gun that could also be very light an compact to go in a backpack, but the backpack gun use case is a bit less relevant today than it was when I originally thought of it.

I have an original Scorpion with the 18x1 threads. I want to get them re-threaded 1/2x28. Do I have to remove the barrel from the trunnion? I have the Pakse handguards and the nut removal tool so I already have the handguards off. I was just hoping I wouldn't have to fight with getting the barrel out of the trunnion and risk messing it up when I go to put it back together. My gut says I will have to remove it.

class 3 machine is the go-to for threading old 18x1 Scrops. He did mine. I forget how much disassembly I had to do, but he does barreled AKs and stuff so it doesn't seem like you'd have to break down a scorpion much. He's active here on arfcom--has a thread in the EE.

I just did the swap this afternoon. I have an S1 that I converted to a ‘K’ with the ILWT tri lug/threaded barrel.
1) Barrel nut too is required. 2) A breaker bar plus an extension helps (slip a pipe over the ratchet handle). 3) Remove the trigger housing, grip, stocks, braces, whatever. 4) Place the upper in a vise securing the HANDGUARD ONLY, not the receiver body. If you break the receiver, your SOL. If you break the handguard, then you can just cut the barrel and handguard in half with a saw if you had too. 5) That barrel nut is snug AF. Heat may help but I did not need it. Once it’s loose, slow turns or you may dent the handguard or scratch sections of the barrel if the barrel nut wrench slips. 6) You don’t need to remove the handguard and barrel completely. 20 rotations of so is just enough that you can slide the handguard forward enough that you get the receiver out of the indent on the top of the handguard. This make it nice as the stock handguard and barrel are ready for re-install if you so choose. 7) Beer. 8) —> 12) Follow install instructions. It’s pretty easy. Torque it properly and it will shoot. Makes for a great afternoon project. I’ll post a pic when mine is done. |

I put the trunnion on upside down and did not realize it until after I slid it all of the way down. I had the Scorpion dissembled already since I was swapping barrels but I found the best way to get the trunnion of was to point the barrel down on something firm but soft, carpet worked. Place a hockey puck on edge on the trunnion and smack it a few times with the armors hammer. Came right off.
Armors block might work too. |

I finally got my vise mounted, a 15mm crowfoot wrench, and a 3/8" breaker bar to try to separate my barrel from trunnion. I used a torch to head the trunnion and put it in my vise. Holy smokes that thing is tight. I ended up bending the crowfoot wrench instead of loosening the barrel from the trunnion. I don't know if I should try another crowfoot, more heat, or what. I didn't want to heat it too much in case I ruin something. I used the torch for about 30-45 seconds (the tip of the torch was glowing) and gave it a try for a few seconds then took it back out and heated it up again. Smoke was coming out of the end of the barrel so it seems like it at least heated the whole way through. I might have to find a pipe to extend my breaker bar.

Rob - Background check was quick for me, roughly 48 hours. Scorpions are pistols and are not considered "semi-automatic's" so you do not have to wait that 10-day waiting period.
