"So this was what I consider my first high end age and for an smg, wow it preforms better than a 170 price point. I purchased the 400 fps version and took it to evike Houston where it shot at 1.4 joules out of the box which is too hot for there. Nonetheless next weekend I took to to an outdoor field with an M90 spring and it shot beyond beautifully. It’s safe to say with this you will be competing very well with higher end aegs. This has the tunable trigger with binary and 2-5 round burst, look up a YouTube video and you’ll see. I think you would be better offf with the 350 fps version because of how hot it shoots, you’ll be able to do indoor and outdoor but if you want the 400 fps version there is a very easy to access quick change spring behind the folding stock. For build quality this thing is extremely sturdy and I could not be happier with it, barrel, receiver, and stock are incredibly tough(also has QD sling points). Slight mag wobble and note you will need to get the mags by double eagle, as far as I know those stock mags are the only ones that work in this Aeg. Should you pick one up? Absolutely. I’d recommend this to a beginner, someone who just wants a smg, or anybody into Airsoft. It’s an amazing smg, definitely am more than happy with what it’s done for me

"First time buying a SMG aeg, and this one did not disappoint. love that it comes with an electronic trigger and a mosfet gearbox. Shoots great right out of the box so really no need for adjusting, incredibly light so it great for indoor cqc. Magazines are easy to come by (if you just buy the ones from Evike)

One gripe for me personally really is that it didn't come with the alternative mag release so i was a little bummed out because of that. But NBD the gun is great and for its price worth it!

"I love this gun. Compared to my Elite Force Competition Kit MP5, this gun is cheaper, has better build quality, and feels way more sturdy. The stock has lots of battery space and is easily accessible without me feeling like I'm going to accidentally open it all the time. It also comes with a Mosfet with an electronic trigger and battery low protection, so I run an 11.1v Lipo in it. I wish my Krytac came with an electronic trigger and battery low protection... It's also great that it comes with a Mid Cap magazine, instead of a Hi Cap magazine that I will never use. If you're considering buying this gun, get it, you won't be disappointed.

On a side note, I think I misplaced the included alternative mag release, or maybe it wasn't included for me. Is there anywhere I can get another one?
