"This thing is FANTASTIC! will fit onto any "full metal" aeg barrel, the front end of an SRC M4 I have will not fit this part without a new delta ring. But I have put it onto a Dboys M4 body and it fit snug as a bug in a rug! :D

It is an EBB (Electric Blow Back) which means the mock bolt will open an close each time you fire not that it has recoil
Full Metal!
Great wiring!
Easy to install (You will need basic knowledge of an AEG)
Uses pins to hold the body, not chicago screws so you don't need a hex wrench to take it apart!
All mags I have (Lonex Flash Mag, Dboys, and JG) fit well, a little loose.

The wiring has a spade connector, and one that looks like the motor connectors, most aeg's front ends do not have one of each, but have 2 spades (like the actual connectors on the motor) You can pick one up at any auto parts store though and crimp it on.
Price is a bit steep you could almost buy a new aeg for that much...

All in all, Definitely worth the price if you need a new, reliable AEG Gearbox, and upper and lower receivers :D! Evike Rocks!!!!!!

"OK...well it does not say it in the description so i will. this is a blowback (EBB gearbox). I got this on sale for 70 bucks. It is fantastic and works great, i am now running an m150 and ultra torque motor. all my friends are super jealous. The quality is good and the body is great. i recommend it

metal body is good for the price
cool EBB gearbox
get a gas blowback effect but without the gas ^^
good recoil kick for EBB

experience is needed for technical problems
you need a decent motor and battery for great performance
its not on sale anymore ^^
otherwise its awesome

"the metal body is really nice has a working bolt catch and gear box has blowback feature. its mechanical the piston catch the bolt and pull it back. the gearbox feels solid but has really cheap parts the only good thing is the full cylinder has a really good air seal. the only problem is that some of the internal are proprietary but still good design and easy to work on.

"Bought this set when it was $120! I had the Madbull daniel defense kit and Matrix LE stock on it. Looks very nice.

The biggest pro is that you can build this into anything you want not wasting money on parts you are going to toss.
Cheap! It is the price of a metal body.
Good gearbox
Low resistant silver wiring
Good accuracy and range. (I used a matrix 363mm 6.01mm barrel)

Had to replace the sector gear after 5000 rounds.
($15 Guarder and 20 minutes of my time, but now it shoots even nicer because I shimmed it.)

"Well I bought this thinking that it would be a good replacement for my Echo 1 gear box that recently gave out. I was wrong this gearbox sucks. I had to buy a new motor and a spring to go with it.

Metal Body

Metal Feels Cheap
to big of stock spring

Webmaster: The description stated this gun shoots 400 FPS....if your Echo1 is old type with standard motor, it is just standard rule to power a 400 FPS with torque up motor. Or, you can always get 9.6V good battery, or change to lower power spring like you did.
