not having a slider is the number one reason for me to pass up a cocker (eye holes is number two). On a sniper its less important, but anything semi has to be a slider. I simply turn a hinge into a blender.
That ribbed body is interesting.
Forum for Sniper 1's to MQ and anything autococking welcome.
