"alright, sportsfans, time for the Engineer Review.
first of all, Echo1 installed the stock themselves. it was installed on a single point plate, and they just remounted the sling swivel, so you are technically getting a single point plate as well.

second, the stock is reversable. pull off the stock...stock, unscrew the bolt holding the end cap on, unscrew the inner screw, and pull it off. reinstall upside down, and reassemble, and the stock folds to the left instead of the right. super cool.

third, the mags (thats right, two of them) fit perfectly in double stack pistol mag carriers.

the buffer tube is military spec, not civilian, so if you want to install another M4 stock, make sure you get the right diameter.

fourth, there are downsides. the paint on the selector markings is easy to rub off, and the grip is about as slick as a gen one Glock pistol. get some grip tape.
The weight. everyone else commented on this, too. its a cast metal frame, not weights, so you can't remove anything to fix it. who cares? it is great!
The charging handle is locked into place when the battery is installed, and only used for ejecting said battery. No faux cycling for you!
flash hider is painted orange aluminum, and locked into place with a setscrew, and glued. I had to dremel it off.
selector is spongy, but improves when you tighten up the setscrews on it. I filed a notch into the pin, so the setscrew locked in better, and now the selector is so positive, it does PT every morning.

"First off let me say this thing is absolutely ridiculous in CQB! I went to a lot of CQB
Places and this gun performed amazingly and surprisingly accurate to such a short barrel. It's a great gun, but be warned, you'll be ripped after playing a few games.

High rps
Good fps for CQB
Very accurate for short barrel
Pretty much full metal.

Magazines are a little wobbly in maxwell but doesn't change performance

"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.
