"This thing is HK SLAPPIN good!
I’ve had it for a little while, and it is a laser at 100 feet with .25bbs. The polymer is absolutely phenomenal and feels very good in the hand. The sights turn with a very tactile and positive click and are really clear, and upon shouldering they are right there in front of your eyes. The selector is also crisp and tactile. The 3 round burst feature is a godsent fore ammo consumption and keeping the motor cooler(that heats up real bad, and real fast in full auto).
There is no wobble at all as long as the stock magazine is out. The magazine is beautiful blued metal that looks like a real mag...but it wobbles in the mag well, and the winding wheel locked up and is now unusable. AND the charging handle, oh boy is it nice, I rubbed my thumb and index finger raw just racking and slapping it. The fire rate is sort of sluggish and the trigger is kind of mushy, not allowing me to rapid-fire in semi-auto with my middle finger. But the hop up works great and is easy to adjust and can over-hop .25s with ease. The metal is beautiful, well painted, and minimally engraved, and I can see it looking beautifully weathered in the near future. The ergonomics, another gift from god, the hand guard is at the perfect angle, and the stock provides the perfect cheek-weld. The grip feels great and is super comfortable. The platform is heavy enough to not feel like a toy, but not so heavy a smaller person can’t wield it for a day at the field.
Sorry for this super long review, but 99% of the things I can say are great, if I could I would buy more. It’s a shame they won’t be back in stock for a long time. (Maybe March 2021 so I’m told)

"If your looking at this gun right now I kid you not it's a great cqb/mid range battle gun I bought the gun bought a slightly longer inner barrel made by Prometheus I think 229mm so not much longer but it still numbed my fps to 400 with .20 gram bb's and 360 with .25 gram also is very consistent with fps didn't go above or under by more than 2 fps so if you plan to upgrade the barrel be careful if you want it for strict cqb use but I play outdoors so it's not an issue for me and the range with my barrel is a good 150 feet or so believe it or not I was getting people at 125-130 ish pretty much no problem past that it took a few more shots but it still got the job done very well I've owned it for 3 years now and only had to fix it twice the problem being my fault lol but seriously pros and cons now
Good fps
Good range up to 150 feet or so with an upgraded barrel only
Good rate of fire for a stock gun 17 I think it was and good trigger response as well
Light weight about 6.5 pounds loaded and all
Easy to reload was a little tight but just buy jg mp5 mags it's the one that comes with it or if you wanna look boss the straight mags but make sure to scrape some paint in the mag well and clean it because you will not easily get the mag out
Basically get the gun cuz um no cons in my opinion just treat it well and it will return the favor

"Got this gun recently and overall, I really like it! The feel is great; A good heavyweight and solid construction! The size is perfect for CQB, but has the punch and range for outdoor as well (I use .25's). I don't really use the three round burst much, but it's definitely a great feature! Hop up is easy to adjust, sights are very effective, but I'm trying to find a good claw mount that actually fits to put my red dot on.

Now, there are some issues. Number one being that my very first game with it, the brass fitting pressing into the grip for the motor plate pulled out and won't stay in. Currently have duct tape holding it in place, but it's a very big issue that should not be happening. Number two is that the magwell is VERY tight! However, some use and mag changes will eventually loosen it up. I noticed it felt better after just one game.

Overall, when the grip screw issue is fixed, it will be my go-to CQB gun for sure! I dress in US Navy camos, so it fits quite well! I'm thinking of buying and testing the ICS lower here on Evike and see if it works. Will update later on with results. I give this gun 4.7/5 easy!
