"After boiling down my options for CQB/short-barreled AEGs, I'm so glad it was this gun that went under Epic Deals. I'm sure the other reviews have already pointed out the amazing pros of this SMG, but I at least wanted to say how easy it is to disassemble/access this gun and how it reminds me of the ACR/SCAR. After a year of use, it continues to shoot without issue and it even accepts my boneyard G&G UMG mags, albeit tightly. I've had two guys ask me where I got this gun and honestly, it would be cool to see more of these on the field. 10/10 would buy again.

"Very good gun. I have had this gun for only 2 weeks now but it has performed great in that time. The trigger response is great and the rps with an 11.1 lipo is around 15-16 rps. The quality also feels awesome. I have used this gun in 1 battle so far and it was a lot of fun to use.

"This is the SMG to beat them all in price and performance. There is quite a bit to love about this airsoft replica. I will rant a bit then get into pros and cons.

The thing I was surprised by is it really is a big replica. I always had this preconceived notion that SMGs were supposed to be small or midsize but it really is just as beefy as a standard M4 or MK18. I wish this was out before I bought a Colt sportsline M4 "Go Airsoft Package" because the UTR45 was and still is by far the better buy. The Colt replica feels WAY cheaper and more likely to break than this.

I have seen full size MP5 AEG replicas and they are just big. Like, a little too big and almost unnecessarily so. And I am a sucker for MP5s. This fits the SMG profile better and it has better battery space and build quality.

- 6.03mm inner barrel already installed (I believe?? I wish Evike would just list inner barrel diameter AND ACCURATE LENGTH in the specs already for all of the replicas they have on their website. For crying out loud it is literally and legitimately one of the top 3 most need-to-know specs and you hardly list it). It is stupidly accurate.
- Programmable firing modes. That is really nice if you just want to run safe-semi-semi. There are plenty of videos teaching you how to program it.
- STURDY construction for a polymer replica. Better than the majority of airsoft AEGs and maybe become the standard for the future of budget airsoft... hopefully.
- Quick change spring system. This can be your indoor AND outdoor setup.
- Rotary hop-up system can get swapped out and upgraded with something like a MAXX HopUp which is great.
- Lightweight. I have a CYMA Platinum "Rapid Strike" PDW (ID: 36346) and that thing is HEFTY on its own. Evike says they are the same weight; however, they really are not. The CYMA weighs more. If you are concerned about weight, go with this over the PDW. Gym rats (who only work out their arms) can ignore this.
- Ample battery space AND connector adapter so you do not have to buy new batteries.
- CWISPY trigger response.

- I had an alternative mag release switch (akin to an MP5 mag release) that was a bit of a pain to get installed so I just kept the original paddle one installed.
- I noticed there really is not much holding the mag in place and it does have *some* wobble to it. If the nub on the mag gets worn down too much just put a small piece of wood or something wrapped in electrical tape as a suitable handyman fix. It is something to consider but nothing to lose sleep over and you just learned how to fix something. Good for you! :)
- The charging handle is cool but, like the mags, does not seem to have the best retention when installed. I have not lost it yet, but I only install the charging handle to adjust the hop-up. Otherwise I keep it stored in a safe place.
- You read the review to this point and have yet to buy one? How is that even possible?

If I were to choose between an M4, MP5 and this UTR45, I would pick the UTR every day of the week and twice on Sundays. Yeah mags are proprietary, but they are SOLID. The programmable mosfet in a $180 airsoft replica is an absolute win. I have not seen many M4s or MP5s that have a mosfet at this price point so invest the money into this. It is totally worth it and you will have it for a while and never get sick of it. But hey, if you don't want this and you want to be a cookie-cutter airsofter with an M4 or MK18, at least buy a SPECNA M4 Core, Novritsch SSR4, or Lancer Tactical Gen 3. Those are all the same thing (tight bore barrels, programmable mosfets and whatnot) and are just as good if not better.
