"I decided to spring the extra few bucks to get this, as opposed to the ATI and Tacstar variants, and am very glad that I did. It takes all of about two minutes to properly remove the old magazine cap, spring and follower, and drop in the new spring, then screw on the new magazine tube and secure the sturdy metal clamp. It is made entirely of a sturdy, matte finished aluminum, which doesn't match the blued finish of my Winchester, but looks good nonetheless, and with a fully loaded magazine of 8 2-3/4\" shells, actually serves to balance out the gun a little better. Overall, I'm very happy with my purchase, and would highly recommend this extension to anyone owning a Winchester 1200 or 1300 series shotgun."
