CZ 12005 Single Shot Adapter 22 LR, 17 Mach 2 1-Rd Black Polymer - Fits CZ 452/453/455/512/513

The CZ 12005 Single Shot Adapter is a dedicated 1-round magazine insert designed to be used in place of the standard detachable magazine on CZ 452, 453, 455, 512, and 513 rimfire rifles. Built from durable black polymer, the adapter accepts a single round of 22 LR or 17 Mach 2 ammunition and allows the bolt to close on that single cartridge.

The unit drops into the magazine well exactly like a standard CZ rimfire magazine, making it a useful training and safety aid for new shooters, instructors, or anyone who wants to limit a rifle to one chambered round at a time. It is also handy for bench-rest and sight-in sessions where rapid magazine-fed fire is not desired, and for walking new shooters through manual-of-arms drills without the distraction of a topped-off magazine.

Sold by CZ-USA under part number 12005, the adapter is compatible with the CZ 452, CZ 453, CZ 455, CZ 512, and CZ 513 rimfire rifles chambered in 22 LR or 17 Mach 2. The molded black polymer construction matches the look of CZ factory magazines for a clean, low-visibility profile in the mag well.
