So I was looking at my buddies S6.5 and I noticed alittle something no one has seemed to mention. So it appears CCM has done it again with another improvement that seems to have gone by silently. They have improved the asa on off by changing it to a piston style on off instead of the old solid pin depressor and o-ring. This makes the complaint of the on off being to hard to turn all better. Thanks for another great step ahead CCM, constantly trying to improve the product, but not tooting your own horn for it.
