"Externally this gun has a good look and body.

Stripped the piston teeth after 4 x 120 Mag

It needs a little bit more QC, but overall great for the price.

"won this in a box of awesomeness , gun feels solid and has a good look , have added a few extras , hand grip, sling and scope now looks bad ass.
performed well straight out the box fires straight and hard put over a 1000 rounds through it when testing it out on fully auto and no problems and motor didn't get hot.

"I bought the gun about a week and a half ago and overall it was amazing the gears stripped on me after 3 games but that is on me not taking care of the gun properly . But the gun is very accurate after adjusting the hop up a bit and if you just put a sight on it like a red dot your set this is a very amazing airsoft gun for its price and i highly recommend this for anybody whos looking for an affordable airsoft gun.
