"Allow me to start off by saying that this is, by far, my favorite submachine gun. It's perfect for CQB and has the potential for field use, though the short barrel makes it better for someone who moves at a fast pace or 'sprays and prays'. It's a must-have gun for recon, especially for the treacherous terrain of the Jungle of Doom arena at CPX Sports (Joliet, IL). Speaking from personal experience, I've used this gun to carry out a solo covert assault and take the hill in said arena in the last ten seconds of a game. This gun is also perfect when used with a Matrix RPG-7.

I actually got this gun for Christmas, 2013. As many have pointed out, the LE stock makes it heavier than the slightly older Echo1 Task Force Black MK5A5. For CQB players, I recommend buying the MP5K end cap ( This reduces the weight, allowing a strong player to wield the gun with one hand. For extra support and a stylish touch, add the PDW foregrip (

There is something that I haven't experienced, though; the default handguard seems fairly sturdy, and none of the rails have fallen off yet. Perhaps it's just luck.

As for performance, this gun shoots at roughly 330 fps with .20g BB's. The rate of fire is high with a 9.6v battery, so expect to burn through midcaps on full-auto. the rail system provides ample space for any scope. Also, if you use the railed handguard, be sure to attach a laser sight, and don't forget to buy a dual mag clamp for the advantage of a quick reload. Be warned, though: the stock must be unfolded for you to load the left magazine.

It comes packaged with two high-capacity magazines and a 9.6v battery. Overall, $250 is a decent price, but you'd be crazy to pass on this when it is on sale.

- CQB-friendly (320-330 fps)
- Compact size when the stock is folded or when the MP5K end cap is installed.
- Ample rail space.
- 9.6v battery and two mags included.
- Compatible with most MP5K parts, including end caps and foregrips.

- The entire flash hider is bright orange, despite the fact that there is already an orange tip.
- Sights are not included, but you'll probably use a red dot sight anyway.

"Great CQB gun.

I like the flat top rail as it made putting on a red dot less of a chore; however, there are no iron sights so remember that.

Only three issues with this gun.

1. LE Stock
The stock has some wobble to it. Not more than you get from a normal m4 LE stock but enough for me to put it on here. Also the nut that holds the adjustment lever in place wiggled its way loose and now it is just a threaded rod. I am not sure if this was just a bad one or if I did something wrong; I rarely pull the stock out so it wasn't a big deal.

2. Heavy for a CQB Gun
I have a full metal PPSH and this gun weighs a bit more than that. It is very front heavy, not just a little. At first I thought it was me b/c I used a lot of traditional rifles (m14 m1) but everyone who holds it all agree that it is one heavy gun. I would get a fore grip.

3.Hop up self adjusts
The hop up is the infamous stick hop up. I hate these because the constantly move while being used and putting the battery into the gun. I kind of solved this by doing the adjusting my hop up and using a zip tie to secure it in place.

Overall, good gun for CQB. Has decent range and good trigger response.

I would get a fore grip and a red dot at least with it.
