ASG CZ Scorpion EVO 3 A1 Carbine Airsoft AEG (Model: Carbine / Flat Dark Earth)

"The good: the gun looks great and shoots great out of the box.
The bad: as a polymer gun, it should be cheaper. The battery compartment is a major pain in the ass to use. I have installed a mock PEQ box on the rail and put a Lipo in it.

"Well I love the gun. Compared to other guns I have bought in this price range this is by far the best. Accurate, fantastic trigger, great hop, decent RPS, and a nice polymer body. Mid caps suck on it. 75 rounds is nothing for how this gun shoots. Battery space is trash for a carbine. The EVO smg battery I bought made specifically to fit this gun is so tight that I cannot pull the charging handle back without it getting stuck and scraping the Lipo which is NOT ideal.

"Super snappy! This thing is great and has a lot of features there are a few problems though. The battery space is limited and I would not advise using any other battery than the one sold by asg for this gun but even that battery will jam the door and the wire might fail due to some strain because of the motion of the bolt cover moving forward and backward. Now on most airsoft weapons this wouldn't be a problem but because you have to pull the charging handle back when loading the a new magazine this can become annoying. My biggest grip though is that sometimes the bullet run out detection doesn't always work (works 6/10 times or so) and on a $400 gun I feel like it should work flawlessly. But this is still a good buy and really is great if you want something different than just another m4.

"Personally I think ASG Scorpion evo doesn't worth this price. It's exterior is good, and it performs well. It will be a perfect SMG airsoft only if the G&G ARP9 doesn't exist. For Scorpion fans this airsoft must be fantastic. But I'm not a huge fan of this.

"I just got it and something is wrong, it makes a terrable noise when I try to shoot it, and shows a red light at the bottom. It is also VERY hard to put a battery In and it bunches up badly. The gun looks great but something is wrong with mine. Also it sucks you have to have a speed loader for it. But shot great until it stared acting up. The first day I got it.. might have to return it

"As usual, ASG managed to screw up another great design by CZ.  

Specifics:
Design: the access to battery compartment is EXTREMELY inconvinient: new buyers be aware you have to :

1. Unscrew the silencer
2. remove or slide forward the handguard
3. pay attention not to loose the bolt and the spring (and pay attention to the order where they fit as the manual does not have any pictures)
4. somehow fit in your battery and all the wires into the tiny space
5. reassemble the whole thing.  
Idiotic is a polite way to put it.

Fit and finish are underwhelming: metal parts are not anodized but spray painted (not a bad as some of the cheaper brands but still) so bolt does not slide easily, the threads for the silencer are rough and dry (remember you have to remove/reinstall every time you need to access the battery)
the front sling attachment is too tiny to fit any of the quick release slings; 
the "ambidextrous" firing selector implementation is flawed, way too loose, and can be easily pushed to safety with your index finger/knuckles (especially when wearing gloves) resulting in you being shot as the gun is on safe.

Performance:
air seal is great, shoots very consistently;
inner barrel is OK, may be a step above the mass market junk but not too consistent (bbs flying within 2-6 ft diameter at 50 ft. definitely needs replacement with something like the maple leaf.  

Bottom line what was a great promise ended up being a major disappointment. Do yourself a favor, buy a Krytac for less and get a better perform weapon.
