Ensure the Quality of Your MSR Ammo

While its easy to grab ammunition out of a box, stuff it into a magazine and go shooting, the possibility always exists that one of your go-to AR rounds might not be within the specifications needed for safe or reliable shooting. Check the consistency of your ammunition with the Lyman MSR Aluminum Ammo Checker.

The Lyman MSR Aluminum Ammo Checker is specifically designed as a simple Go gauge that allows sporting-rifle owners to drop their ammunition into the checker to ensure that it's within the minimum specifications and entirely safe to shoot.

  • Machined from 6061-T6 aircraft-grade aluminum
  • Features hard-coat anodized black finish
  • Allows for quick, simple checking of single rounds

The Lyman MSR Aluminum Ammo Checker is available in multiple calibers and gauges, including 5.56 NATO, 6.5 Grendel, 6.8 SPC, 300 AAC Blackout, 7.62x39, 450 Bushmaster, 458 SOCOM and 50 Beowulf.
