We are excited to announce the end all chamber flag reinvented for CZ-USA 22LR rifles and aftermarket chassis than only take a 10 round mag.   If your chassis will NOT accept a 5 round CZ magazine then this IS the MagFlag for you.

LONG version = chassis that can not take a 5 round magazine.  

The Yow-Tech CZ MagFlag!!!

With all the request we have received for PRS specific action and chassis solutions, I have expanded the offering to CZ-USA 22LR Rimfire rifles. The CZ MagFlag 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 visible from extraction area.

  • Safety Orange, Red, and Yellow color options.

• Mechanically 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??)

100% Guarantee compatibility with chassis that can accept 5 round CZ 22LR magazines.

Tested in the following rifles and aftermarket chassis:

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

• CZ 452, 453, 455, and 513

• Chassis RigidAlloy for 455
