This is a great upgrade for the cocker. Its light at 12 grams and so It reduces kick as this really helps out an an e-cocker. My aluminum block weighed in at 27 grams. This block made a noticable difference (coupled with a spring kit). Normally I use something longer before I review it but there isn't much else to be found out.
At first, I thought that the pump arm would strip out the delrin, but it hasn't. This could be because I use a lighter spring and the LPR pressure is less though. I chose this over the slik because it was cheaper, was light-weight enough for me, and didn't look a thong on the back of my cocker.
The only real problem for me is the threaded hole where the pump arm screw in. CCM drilled it too far out. What this means is that when you twist the pumparm in toward the body so that it stays in the groove that it was meant for the block turns counter clockwise so that it sticks out on the right side of the body. This makes it really difficult for the ram to cycle. The solution to this is to turn the pump arm clockwise which makes the rod stick out from the body. This makes the back block level and more importantly reduces the resistance. This probably puts excess resistance on the ram and could probably lead to problems.
Being a CCM product this (pump arm problem) probably doesn't happen on their cockers, but since most people own other cockers it is an issue.
Overall, this is a great product. Even though I am giving it an 8 because of the very annoying pump arm problem it still is a very good buy and I recommend it. Though, it is mainly meant for e-cockers to reduce the kick.
Props for the wooden pull pin. I was thinking of doing one myself on a lathe. maybe make a few at a time.
the solution for your pump arm problem is to allign the pump arm in your bacblock, loctite it, then unscew the ram shaft from the pump arm untill you have a proper gap between backblock and body and locktite it.
Someone needs to make a super light pump arm with a turnbuckle so it has adjustable length.
