No. It's the small rubber buffer that makes direct contact with the back of the glock. It's hard to explain but turn the kpos g2 over. Unhing the rear portion, there will be a small rubber bulge with 2 Small holes next to it. This part has way to much movement and can be pushed in with ease. When the back portion is put into place on the glock this rubber part makes direct contact with the glock. Because it has give the whole rear end of the kpos moves up and down. This is the problem.

Sorry, for some reason I was not getting notifications on this thread until the last post.
I was confused because the part you are referring to is not made of rubber, but aluminum.
Because of the use of polymer, the frame dimensions vary from Glock to Glock. If there were no give, some Glock frames would be damaged and others would fit too loose. So a strong spring presses the back plate forward against the pistol frame. When you take your firing stance it pushes the stock tight against the spring. This is not a problem. If you are shooting correctly, the stock will be pressed against the chest and will not move. Only if you are shooting with an incorrect stance will you see movement.
This is more noticeable on Glocks, because the Gen 3 Glock has a frame that is flexes much more and more easily than previous generations. The spring in the Glock KPOS had to be lightened, or the Gen3 Glock frame flexed too much and could malfunction. My personal experience and that of our customers and others has taught me to avoid Gen 4 Glocks and stick to Gen3. This is my personal option, not a policy of Mako. With the lightened spring, the Glock KPOS is as reliable with the Gen4 Glocks as the Gen4 Glocks are themselves.
