Great gun, this review will be a little long, as im going to try to cover everything.
The body IS a VERY high quality plastic, you can kinda imagine what it will feel like, i cant really compare it to anything because most companies dont use the same material G&G does.
Mine chronoed at 405, so the ROF is a little slower, im still getting around 18 bps on a 9.6, but id rather have my gun shooting 350 and getting 20 bps, with thekind of gaming tactic i use, i need and EXTREMELY high ROF.
The crane stock is also really hard to get open, you have to take the actually crane stick off and pull the wire out of the buffer tube because on mine it was still in there, and i dont keep the 2 pieces of the stock on mine, i use the one smallest piece and tape it over, because the little tab part is EXTREMELY hard to pull off, took my dad 10 minutes and a pair of pliers.
I havent gotten the flashider off mine, but the barrel is convertible and the inner barrel sticks out a bit, with the longer barrel part on the inner barrel stops where the flashider starts, so its meant to be like that.
To clar up any confusion qbout this, i am 90% sure there is a tighbore in it, the barrel is the silver color i forget what material that is, and the accuracy is amazing, perfect stream of bbs with the airsoftgi .25s.
The blowback is nice, doesnt actually make any recoil it just shakes the gun a little bit and makes a small amount of noise but it adds an amount of realism no other gun has
The D.D. RIS is really nice, metal and 9 inches. i like it alot
The ROF with 405 fps
lighwieght, durable plastic
450 round high cap
D.D. RIS is awesome
33 inches long, little big for CQB but i get by with it.
The magwell on mine is broken (actually the hop up is a little slanted so the mag doesnt click in all the way, mag just falls out sometimes)
body scratches easily
motor heats up fast
flashider is hard to, or doesnt come off
crane stock is hard to get used to with the tabs and stuff
for this price, you can almost get a G&G proline m4, (but no RIS, or crane stock)
performance wise, there isnt anything wrong
Overall, great gun!!
