Well it is a lot smoother action .
I like mine a lot .
How it works ..
When you pump, the rod on the pump arm pulls back the bolt. With the CooperT bolt, the rod connects into the back of the bolt, and when it is pulled back, it releases the 2 ball bearings that stick out the side of the gun. It makes it much easier to pump. I do recommend them.
It sounds like you are a new owner, there is also a quick mod you can do. Take the bolt out, (watch for the ball bearings) and there is a spring in the center there. You can slowly trim bits of that spring away, and it will also make it easier to pump .. not a whole lot though, not as much as the CooperT. CooperT shipped my bolt out quick when I ordered it from him, very nice guy.
