" Turned my M249 into a laser. Hops anything between .3s and .4s no issue. HPA Set-up.
" 80% black is for VSR cut barrels only
Ares S2 striker the short barrel version
worked amazing with a crazyjet barrel gave me the performance I needed, With .42s shoots like a laser.
" This rubber has bumps on the sides of the hop up patch that don't allow it to fit on the inner barrel correctly. Even on a maple leaf barrel. So there not for KJW pistols that's for sure.
