Things I liked:96% identical to the real thing, got lots of buddies in the military who tell me how realistic it is. the mag capacity is insane, just make sure u have either an extra clip or an easy way to reload in case u like to spray and pray. if you charge the battery correctly it can easily last you a weekend of matches. also, bayonets can attach on the end if u like to scare your friends, careful tho Things I would have changed:sturdy up the collapsible stock a bit, make a fore stock piece with a picatinny rail so under-barrel accessories easier to find. What others should know:careful when chaining up the bbs in the clip, don't over do it or you will break the recoil spring on the inside then you will have to take it apart and reset the spring, major pain!
Things I liked:the weight, the look, the quietness, all of these make a sniper wut it needs to be. grant it i had to change the bi pod. but that was all, i took the hop up and completely backed it out and it shoots to the right but its scary accurate at close range. Things I would have changed:to be able to tighten the stock better What others should know:the hop up is hard to find at first, but its a small allen head in front of where the clip comes out. if you know how to dial hop up in u can prolly get some good distance out of it
