A home made rocket cock made out of a face cloth ;P.
Marker Setup:
98 custom with adjustable stock and a one point harness with a rocket cock and a raised lapco sight.
Strengths:
It quets the gun down a bit and it keeps the crap out.
Weaknesses:
If you have an adjustable stock you cant close it all of the time.
Review:
This is a good buy if you play in harsh conditions but if you play speedball you dont need this too to much. i play in sandy conditions and pretty much all of the crap stays out of the gun, and it makes you feel alot safer when you slide.
