"Excellent XM177E2 replica with a few exceptions. Let’s get the quirks out of the way - the hand guard. I understand the manufacturer decided to use modern hand guards for battery space yet for those trying for realism it is not the best fit. Time period hand guards are available from numerous places for 20 or so. Second gripe, if you do acquire the period hand guard you will need to rewire to the rear. If you are not good at soldering, insist on grabbing a rear wired mosfet unit. After these two have been sorted you will be a proud owner of an AMAZING replica with excellent performance. There are reports the original Cyma mosfet will burn out after use on an 11.1 battery, be aware of this if you intend to use an 11.1.

Questionable mosfet

"I bought this gun to scratch my retro AR itch and it certainly does the job. Very sturdy build with beautiful Colt trademarks to go along with it. Unfortunately, it comes with a bad mosfet and beefy M4 handguards instead of the slim car-15 handguards. I'd recommend replacing the mosfet first especially if you use 11.1v batteries.

-Very sturdy. I think they used aluminium alloys just like the real ar's.
-Colt trademarks :L
-comes with SHS 13:1 ratio gears
-retro AR
-deans connector
-selector switch is very positive

-Big and beefy M4 style handguards
-Bad mosfet

"This is one of the best aegs I've gotten in quite sometime! It shoots really accurate and its really compact!

I just got this for Christmas and its great for my Vietnam reenactment kit and the cyma platinum gearbox is just great!

The XM177E1 is a good aeg and kinda unique and the colt trademarks on the upper receiver really neat!
