We are excited to announce the end all chamber flag reinvented for CZ-USA 22LR rifles and aftermarket chassis.


Short = Chassis that can take a 5 round magazine.


The Yow-Tech CZ MagFlag!!!


With all the request we have recived for PRS specific action and chassis solutions, I have expanded the offering to CZ-USA 22LR Rimfire rifles. The CZ MagFlas is compatible with the new CZ 457 Varmint AT-ONE and all the 457 models.   This is leap forward in compatibility for common chamber flag system that can be use across a majority of rifles used in NRL22 matches.

  • Prevents loaded magazine to be loaded

  • Indicates that bolt is blocked with bright color visiable from extraction area.

    • Safety Orange, Red, and Yellow color options.

  • Mechanicaly prevents bolt from moving forward.

  • Has holes that indicate there are not rounds in this Yow-Tech MagFlag

  • Safety indicator flag included of your choice in style and color (see site for options)

  • California compliant (0 round mag??)) ha ha


100% Garentee compatiability with chassis that can accept 5 round CZ 22LR magazines.


Tested in the following rifles and after market chassis:

  • CZ 457 American, Lux, Scout, Training Rifle, Varmint, AT-ONE, MTR
