EPeS Airsoft CNC Machined Hop-Up for A&K / Cybergun / Classic Army M249 Airsoft AEG

"I'm looking at the part right now, along with my:
Cybergun FN Licensed M249 "Featherweight" Airsoft Machine Gun (Model: M249 E2 / 400 FPS)
Unfortunately, the larger end if the unit is larger than the Mock barrel on my Airsoft Gun. So no, it does not fit this model. However the quality of the part is amazing. It's all metal,(probably an aluminum alloy because it's light) and comes with everthing shown in the product image, plus some spare rings, and screws. I never actual spent the time to find an install video(which in reading the comments I don't believe exists...)because withing the first 5 mins of dry fitting the peice I found it wasn't gonna work. I'm still giving this part a good review because of the high quality material, and all the spare small stuff they send. Buying the wrong part was a mistake on my end, which I was prepared for, because I also bought the stock hopup for this in the same order. I'm gonna install that now.

"This hop up is a really really good upgrade from stock and #1 key don't get frustrated when putting this together it will be worth it being patient. (Also my hop up adjuster is red not orange which is awesome) Works on my A&K M249 just fine!

"Very happy with this upgrade HopUp used it in my A&K MK46.
Solid construction and came with everything needed to install properly. Much more accurate and bigger range of hop.
