This magazine release has a great design and is well made. Installation was very simple, only took about 15 minutes and no special tools were needed. Also, no adjustments to the magazines, the release or the gun.

I purchased this magazine release for my CZ 457 MTR that I set-up for NRL22 Base Class. With the ten and 13 round magazines the low-profile magazine release was not always easy to find or manipulate, especially when shooting off of barriers or prone. The size and shape of the release is easily located and distinguished from the extended magazine, so finding and manipulating it is a breeze, even under pressure. The leverage from the extended length means the heavy spring can stay, so when the magazines are seated there is an audible "click" and they are secure.

This magazine release is a "must" for anyone using their CZ for competition or bench shooting.

I hated spending $25 for a simple small part but having done so, I'm very happy with the mag extension. I have an aftermarket stock on my CZ that made finding the mag release a bit of a nusance, this fixed that.

Best by far of the extended mag releases!! Works perfectly, great function?

Purchased for my CZ 457 Varmint - this is a simple must have for CZ shooters. Very easy to install and makes magazine changes so much easier!
