***UPDATED Design - now compatible with MPA & MDT ACC chassis***

Magazine Block / Chamber Flag for CZ 22LR Rifles - fits 457 / 455 / 453 / 452 / 513 / 512
Safely hold your bolt open for ranges and matches that require mag blocks or chamber flags, without putting plastic into your barrel.  Perfect for NRL22 & NRL22X and the growing rimfire precision matches!  Each flag is printed with high quality and attention to detail - not the square and blotchy prints other suppliers are selling.

Design Features:
  • Flag is designed to prevent contact with extractors
  • 10mm longer than standard 10 round magazine for use with extended magwells
  • Rounded corners for smooth handling
  • Top of block is tapered for easy insertion
  • Lanyard hole for attaching optional flag tags or lanyard of your choice
Embroidered tags available for an extra $4 - now in more colors!  Tag color will match mag block color unless otherwise noted.  Please send a message if you'd like a different color tag.

Colors may vary slightly from those pictured.

Most orders with ship within 1 business day.
