"Great starter gun for GBB. Be aware though that GBBs generally need a little extra TLC than those sewing machine sounding AEGs.

Accuracy is top notch
FPS is adjustable
People get terrified when they hear you
Very real feel and realistic field stripping
Good hop-up
Removable top rail exposes a rail for a scope if you want to DMR

Gotta keep it lubed up
Magazines extremely prone to leakage
Firing automatic could risk a misfire and a broken loading nozzle (one of the only plastic parts of the gun)
This won't cooperate in cold weather
by Jean-Pascal S. on 07/10/2013
"Ok, i got this gun and it worked for a day, then the mag started to give out, and the bolt cracked... i replaced the mag, and the entire bolt carrier, and made sure everything was lubed up, and i couldnt get this gun to work again for more than 4 shots.

good recoil
shoots hard
amazing body (one of the best features of this gun)

poor internals
upgrading said internals can get way too costly for what its worth
leaky mags

all in all, maybe i got a dud, but it seems to be an all too common story with this gun to have it be just a dud. your better saving a bit more to get a KWA LM4 or perhaps a G&P, if you prefer this platform
by gavin p. on 04/26/2013
"Awesome gun!!! Just got it and it shoots amazing!!! Fires 450fps with propane and is great in summer outdoor games (gas mags freeze up in the cold) put a good lot of bbs through this thing And only one part has broken so far.

Realism is pretty awesome. Turns heads
Build quality is great (its a king arms what do you expect?)
Blowback is very realistic
Fps (great for outdoor use!!)

Broke loading nozzle! (Get a g&p one when you get this rifle)
Mag freezes up in cold (all gbbs have this problem)
Mag leaks a bit (get the regular g&p or the 39rd pmag! They are much better!)

Ammo capacity isn't that big of a deal for me. Overall a great gun and is King Arms quality!!
