"MUST use 9.6V nimh or up battery this gun likes no less! other then that AMAZING GUN!
by Luc Y. on 02/06/2017
"So I got this gun a few months ago and it still shoots like a charm. I put an 18$ suppressor on it and it really does change thw sound to a nice silent pop. But On to the gun, I dropped it on my 2nd day using it in a game, and well the only things left on it was a small little crack in the receiver. The ROF is nice, it shoots around 370-390. Knights armmaent did a good job though. If I were to upgrde this gun, I would definitely change to a metal reciever, magpul stock. But there is one thing you should know, the railing on the barrel is not compatible with certain grips, I had to leaarn that the hard way.

"i have to say this rifle is cherry I picked it up and the front end is a little heavy because the key mod rail. I use it as a DMR because its extremely accurate. Just throw on a scope (4x32) and on the side i threw on a red dot ( so i can switch in between ) your ready to be a marksman.
