first thing to do is swap out the trigger and springs. get an extended mag release
though I never have a issue with mags , they jump out when released |

ETA: just as an experiment....can you do me a favor. Take your EVO and insert an empy mag. Pull back the bolt handle and let it auto lock but do not push the handle to the manual lock position. Hit the mag release. Does yours drop free in that condition? Mine does not regardless if I have the factory or the HB unit installed. |

Hit the mag release. Does yours drop free in that condition? Mine does not regardless if I have the factory or the HB unit installed. Yes, mags don't drop free when the BHO engages holding the bolt open. I'm a bit disappointed by this. I found if you kinda rotate the gun quickly on the long axis, you can kinda fling the magazine out. Haven't shot my fauxpressor carbine yet, but I really like it so far. I slapped a Lucid M7 that I have on it. Inexpensive and OK RDS... but yeah, the reticle is tilted a bit. It's got a dot with a circle around it, and the circle is interrupted at 12, 3, 6 and 9 o'clock, but it's canted a little bit. Would be nicer without the breaks in the circle. The trigger isn't great, but I still expect the gun can be stupid accurate. I'll probably get out to the range next weekend... I have a CZ PCR coming in this week, and I want to get trigger time on it, too. |

How's your hammer wear?
Can you post a picture of the muzzle threads? |

Nice work with anti walk pin, I'm sure soon that will be an aftermarket must. great work thanks for sharing.

View Quote I think if anyone is gonna run anything but the factory mag release, I have a feeling this might be a necessity. I was going to just turn one end large like the trigger group take down pin but then I would not have had a way to cinch down on the pin if the screw didn't want to budge ( I could have milled flats but time was of the essence ) ....hence fixing a screw on one side and then just blue loctite on the other. I forgot to send myself the print.....if I remember next week, I'll put some GD and T on it and post it. |

I got the front sight unstuck......and then realized that no matter what I do, the factory sight will NEVER EVER be able to come down low enough to raise impact to where it needs to be at close range. The lower the skirt of the front sight, the more the detent is depressed. I would need to remove material from the detent AND deepen the detent hole a LOT in order to get enough elevation to bring my close range sight picture to where I need to be and have room for the skirt to keep moving downward. It just isn't worth it. I'd have to do a full layout, dimension it and then plot several tool paths to coincide with the features that already exist. SCREW THAT!!!
No such problem with MagPul's standard BUIS setup. I had my windage and elevation co-witnessed in like....I dunno....40 seconds? The factory sights could not co-witness to the Spitfire AR due to its' height. That is no fault of the sights....BUT not being able to adjust irons for close up work IS the fault of the sight design. I may just go to the range again tomorrow and test those irons independent of the scope and then co-witnessed. Mind you that the Spitfire AR is NOT a true 1X scope so the front sight cannot focus nicely with he optic in the way....that being said....unlike my .308.....this comes in almost focused so I will play with it for funzies. If I go, I will also report on the hammer and bolt wear after the next 100 rounds. |

by a magnet in the closed position....there are so many better ways this could have been accomplished...but it's semi serviceable. Open lock is fine and fairly sturdy. Cheek weld for open sights was great. Too bad the sights can't be adjusted for elevation. Windage adjustment was fine, by the way. No problems. View Quote Agree.. I prefer my gen1 stock (held in closed position by a hook) and the european LPA sights. |

Good writeup, thanks. I have a EVO pistol that I made into a SBR and while I like it at least on mine the recoil impulse is harsh and nothing like the MP5 I fired in a class. Still it is a really nice gun and mine has been 100% both suppressed and not and I imagine yours will be as well. |

Frenz, thank you for the pics. Those are some VERY nice components!!!!! That is a great looking weapon!!!

Not to side track or be a smart ass, but why a 30 foot zero? That's going to give you a pretty rainbow-like trajectory. I've always liked the 25 yard zero for 9mm carbines, since you have a rough return to POA at 100 yds.

So the EVO carbine - is the faux suppressor removable or can one be added to the carbine model that doesn't have one?

I put some Magpul MBUS sights to reblace the factory sights that I can't get to go low enough.

Got mine out to the range Sunday morning. 150 rounds shot... my trigger finger has a blister on it from the safety lever. That will be swapped in a couple weeks!
Trigger isn't great, that's for sure... so I'll be doing some upgrades there, at least eventually. Recoil impulse is a bit more stout than I expected, but there is a big heavy bolt slamming back and forth in it. Not a single operational problem. 150 rounds ran like a top. 2 magazines of Blazer Brass, 1 of WWB, 1 of Perfecta and 2 of Wolf steel case. All ran like a top. After payday this week, I'm going to order something for the safety (probably the AK style thingie), an extended charging handle, sling mount and probably some trigger stuff. I THINK mine has the welded nut in the trigger group. I'll have to check. The trigger def. needs some sweetening up. I haven't cracked it open to look at the hammer face. I'll try to do that tonight and update here. |

BUT, even though it is lighter....the factor carbine is a HELL of a lot easier to run than a metal stocked Uzi. These guns are reallly fun and easy to shoot. SPEAKING OF THIS VERY THING: I picked up some other different ammos today. I got a selection of 115 grain and 124 grain bullets to see how they run. I want re-iterate that when I first ran both 124 and 115 grain Winchesters, the extractor was not snapping over the rims when the next round in line was dragging on the bolt at the beginning of a full mag. HOWEVER: in each instance that issue went away at the NEXT full mag. I think the mags AND the extractor spring just need some break in cycles. This is a pure "push feed" gun, like an AR and the extractor must snap over the rim of the case during chambering. This week I am testing German MEN 9 X 19 115 grain FMJ, Remington Green Box 115 FMJ, Blazer Brass 115 FMJ, Aguila 115 grain FMJ and some Hornady American 115 grain XTP hollow points. For some odd reason....a crapload of the 9mm was out of stock this week. I want to run more 124 as there is definitely more of a recoil impulse with it. That begin said, the polygon rifling throws them very accurately so far. |

You will need it....some of these carbine screws are seriously welded. With FILLER metal. Make sure to get the HB spring kit with the new screw for the trigger pack cage. The springs make the trigger MUCH more manageable. |

Matthew_Q: Is your gun as accurate as mine? I saw a youtube video of a little girl shooting one from the standing and she was also punch a single ragged hole in the target. Granted, like me, at CQB range....but my point is that this gun is FAST to get back on target....and mine doesn't even have a brake.

Quoted: Okay....so first, here is the hammer at 800 rounds or so: http://www.ar15.com/media/viewFile.html?i=90892 It's getting pretty darn beat up. This needs some fixing. Gotta email CZ about this. Now, take a look at these two rounds. One is Winchester and the other is Aguila: http://www.ar15.com/media/viewFile.html?i=90896 This was the severe smackdown these were getting. Tis first happened only twice during the inital break in but disappeared quickly. Once the gun got dirty and I tried to use new mags...cartridges would smack the RMAP ( or a part of it ) really hard and get bent. They would still try to chamber but the extractor would not snap over and the gun would fail to fire. The more I thought about this, the more I realized it seemed to occur at a particular "meter"...like "bang, bang, bang, jam.....bang, bang, bang, jam". I began to wonder if the rounds on one side of the mag were always the culprit. When I analyzed the feed ramp area I noticed that the left corner had this nasty sharp projection right on the left side of the ramp. Too, the extractor spring was SOOOOOOO STRONG that I could not even begin to move the spring tension with my fingers. The extractor was REALLLLY digging into the base of teh cartridge during the end of the feed cycle. I decided to kill two birds with one stone....and a few dremel bits. First I stripped the gun down and washed the damn thing...it was filthy. Then I first took the upper and lower sharp edged off of the extractor and polished the FRONT ( only ) of the hook to a mirror sheen. I then found a gunsrping with about 75 percent of the OEM diameter but the same length. http://www.ar15.com/media/viewFile.html?i=90891 http://www.ar15.com/media/viewFile.html?i=90894 I installed the "new" spring and found that it was MUCH easier for the round to sanp over the case head....but it seemed ejection was a bit weak. After re-installing the OEM spring....hand ejection was the same. I have the thinner spring saved but left the OEM one in because of the things I discovered a bit later. After working over the bolt, I then polished the feed ramp. I got the left side much smoother and though I got that nasty edge. Then..when I reassembled the gun...there it was again!!! WTF???? It was then I realized that the trigger housing uses a metal core for the trigger housing front pin and it was the sides of the housing block that were wrapping around the trunion and resenting the nasty edge. Soooo.....I profiled that to blend with the feed ramp. http://www.ar15.com/media/viewFile.html?i=90893 Above each pin lobe you can see where I rounded the metal off. All of my damaged bullets have a nice ding on the nose that I am GUESSING was from those lobe projections. Now the ramp and the lobes blend nicely. In this lousy pic you can see the polished lobe corner in conjunction with the feed ramp. http://www.ar15.com/media/viewFile.html?i=90895 The gun now feeds from both sides really well but that left side is a LOT better. A LOT. I also polished the throat while I was at it. The gun feed very smoothly. So, with those details taken care of, the gun was fully sink and soap washed and rinsed. I flushed it with WD and then oiled it with Break Free. I will go out again on Thursday and test it with the ammo it hates the most: Winchester and Aguila. We'll see how it goes. The feed ramp should self clean now....it's smooth as glass.....instead of holding filth residue. More to follow next week. View Quote |

Thank you. I spent a bit more time on those pin lobes this morning, shaping and dressing them for a bit more optimum performance.
Dry cycling a full mag of Winchester and Aguila ( my two biggest problem children ) I noticed that the projectiles now do not have dig marks on them. Too, the cartridge bases are not gouged by the extractor either....even though I am running the full strength factory spring. I'll update function on Thursday night. |

Thanks for those updates.............I like the Evo, but this is making me reconsider the one I have on layaway...........it shouldn't have those kinds of issues right out of the box

Okay....so first, here is the hammer at 800 rounds or so: http://www.ar15.com/media/viewFile.html?i=90892 It's getting pretty darn beat up. This needs some fixing. Gotta email CZ about this. Now, take a look at these two rounds. One is Winchester and the other is Aguila: http://www.ar15.com/media/viewFile.html?i=90896 This was the severe smackdown these were getting. Tis first happened only twice during the inital break in but disappeared quickly. Once the gun got dirty and I tried to use new mags...cartridges would smack the RMAP ( or a part of it ) really hard and get bent. They would still try to chamber but the extractor would not snap over and the gun would fail to fire. The more I thought about this, the more I realized it seemed to occur at a particular "meter"...like "bang, bang, bang, jam.....bang, bang, bang, jam". I began to wonder if the rounds on one side of the mag were always the culprit. When I analyzed the feed ramp area I noticed that the left corner had this nasty sharp projection right on the left side of the ramp. Too, the extractor spring was SOOOOOOO STRONG that I could not even begin to move the spring tension with my fingers. The extractor was REALLLLY digging into the base of teh cartridge during the end of the feed cycle. I decided to kill two birds with one stone....and a few dremel bits. First I stripped the gun down and washed the damn thing...it was filthy. Then I first took the upper and lower sharp edged off of the extractor and polished the FRONT ( only ) of the hook to a mirror sheen. I then found a gunsrping with about 75 percent of the OEM diameter but the same length. http://www.ar15.com/media/viewFile.html?i=90891 http://www.ar15.com/media/viewFile.html?i=90894 I installed the "new" spring and found that it was MUCH easier for the round to sanp over the case head....but it seemed ejection was a bit weak. After re-installing the OEM spring....hand ejection was the same. I have the thinner spring saved but left the OEM one in because of the things I discovered a bit later. After working over the bolt, I then polished the feed ramp. I got the left side much smoother and though I got that nasty edge. Then..when I reassembled the gun...there it was again!!! WTF???? It was then I realized that the trigger housing uses a metal core for the trigger housing front pin and it was the sides of the housing block that were wrapping around the trunion and resenting the nasty edge. Soooo.....I profiled that to blend with the feed ramp. http://www.ar15.com/media/viewFile.html?i=90893 Above each pin lobe you can see where I rounded the metal off.

I have two waiting to get paid for. I was also thinking how do these things work in full-auto if the semis keep going down. Is it maybe QC issues with this year's rush to get stuff out the door? |

I was thinking the same thing. Don't get me wrong...the Evo is a gun with GREAT potential.....but this gun is NOT a fully developed piece. No way...no how. That being said...it is annoyingly close. Fortunately, the aftermarket support on this gun is already outstanding....unlike, say the ACR ( though that is improving no thanks to Bushmaster or Remington ) That being said; CZ needs to get off of their collective asses and get that hammer issue addressed first. The other stuff isn't THAT critical. |

How much of a PITA is it to replace the trigger springs. I have the springs just need a stress free day to attempt it.

I have about 3 weeks till my layaway is paid off to decide whether I want to stick with it or not...............I will continue to watch this thread for CZ responses.........
The weird thing is I haven't read any similar experiences with the Evo pistol.............. Quoted:

The weird thing is I haven't read any similar experiences with the Evo pistol.............. View Quote Ya know....though there are things such as the safety DIScomfort and the hammer issue and some other things.....let me say some positive things about this gun: SHOOTABLE AS ALL GET OUT. ACCURATE AS HELL!!! With the HB accessories or accessories offered by some of the other groups out there, this gun goes from "meh" to "verrrry cool" in short order. I think my reliability issue is something you may or may not see in some guns. I DO believe I have it licked but won't know till Thursday for sure. That being said, the magazine, feed ramp, bolt and barrel design are definitely a very GOOD general design but the trigger group lobe issue should have been caught a long time ago. Again, the DESIGN is sound but the execution is a bit lacking. The carbine should have gone under a bit more development....it could have been perfect.....like I said, it is ANNOYINGLY CLOSE. Once I get my Thursday testing done, I'll definitely update as to the performance. I have enough Winchester and Aguila to make a good diagnosis. After that I am going to make a comprehensive addition to this thread addressing all of the positives and negatives I have about this gun from the user, design, manufacturing and engineering aspects as best I can.. That is going to be one long post. I should have about 1000 rounds through the gun by that time, Lord willin' and the creek don't rise. |

Looking forward to reading the final assessment
