"This cylinder worked fantastically I had no problems with it at all. The cuts at the end help to draw in more air and the ripples help to hold the cylinder in place better than a stock one. I highly recommend this cylinder for anyone looking for great performance

"I got this cylinder to use in my echo 1 platinum m4 and the second I installed it and tried it it was way too tight for the stock piston head to where it wouldn't even move and it fried the fuse because of all the resistance and heated the wires and melted the insulator between the wires and now I need new ones because they short and maybe a new motor all because I got this cylinder. Overall I would stay away from this because I need to replace a lot of part in my gun because of it.
