What your really paying for in this gun is the internals because the externals on this gun are, well... garbage. Says the externals are made of polymer but its not, at least most of it isn't. The stock is wobbly, the outer barrel is cheap plastic, the receiver is ok, pistol grip feels alright and the stock is ok as well. Alot of people will tell you to pick up a jg or combat machine over these but I'll tell you right now that the internals of this gun are better than your combat machines. As for JG I've never owned a JG so I can't really compare.
6.03 Tight Bore Barrel ( Combat Machines do not come with tight bore barrels)
Ball Bearing Spring Guide ( something that combat machines don't have)
Relatively Decent Motor ( Stock G&G motors are garbage)
Everything you need to get started for the most part( gun,hi-cap mag, battery, charger, 1000 bbs)
NOTE: This gun uses 7mm bearings if you plan on upgrading to bushings, ( I tried 6mm bushings and they were too small and tried 8mm ball bearings I had on hand and they were too big).
The rest of the internals are pretty much the same as the combat machines:
Type 2 cylinder
Ported piston head ( didn't bother to check if it had bearings/ball bearings but it probably doesn't)
Crappy plastic cylinder head w/ single o-ring and 1/8in sorbopad ( combat machines actually only use a 1/16 in sorbo so that sucks even more!)
Tappet plate, selector plate, cut off lever, trigger, trigger contacts,wiring, gears are all relatively the same
Not very good externals
This gun does shoot a bit hot, probably want to use a m110 or m100 spring in this gun. ( Lancer Tactical says this gun uses a custom m120 spring whatever that means)
