"I guess for the AMAZING price this gun is good but in terms of quality... no. It is plastic and it leaks a ton of gas so you have to be very careful how you treat it. On top of this the trigger is really hard and inconvenient to pull so brace yourself for that. The accuracy sucks too. The biggest up for me is the velocity, sweet design, and the price. If it weren't for the 60 dollar price I'd give it a 2 out of 5

"Well this gun is one heck of a deal. I have had mine for a month and it shoots beautifully

Great price
Super high fps. (423 with .23)
Easy to do a pistols match with
People underestimate the power of it
Super easy to strip and upgrade

Trigger pull is long and heavy
Too hot for most fields (just sneak it in in a holster)
Inaccurate 50% of the time with. 23
Hopup is nearly impossible to adjust (use heavier bbs or buy a new hopup)
Mine didn't come with a hopup adjustment tool

Overall: This is a great gun. The pros outweigh the cons for me.

Side note: I am working on a lighter trigger for this. I will post results in the forums.

"Great pistol. I've had mine for about a year or so, never had any real problems with it. Just make sure you buy .28g or .30g bb's or it wont be accurate past 50-75 ft. Made the mistake of buying .25's for it. Trigger pull is tough, but you get use to it with practice. I run mine using a propane adapter (it's a plastic one I bought on evike for $15) and it works as good if not better than green gas.


-Great price
-Lightweight, but rugged
-High Fps
-Accurate, but only with heavy bb's (with .30's I've gotten headshots at 100 ft)


-Loud (can be a pro because when people hear it they think twice about charging at you with their AEG)
-Mine doesn't work well if it's cold out (Gas gets weak after half a magazine)
-Low capacity magazine (buy .30's, spend your time and aim and you won't need more shots)

Overall an amazing gun at a great price. 5/5
