Low-Drag High Visibility 12 Gauge Shotgun Follower (12GSF)

The Phase 5™ Low Drag, High Visibility 12 Gauge Shotgun Follower (12GSF) is designed to feed smoothly with no binding in most factory 12-gauge magazine and extension tubes. The 12GSF is precision machined from solid 7075-T6 aluminum bar-stock, in the U.S.A. and comes in orange, red, blue and green anodizing with bright white lettering and a center hole to help verify that the magazine tube is clear by sight and touch.

  • About one third of the bearing surface of a stock follower for smooth feeding and no binding
  • Bright orange, red, blue or green anodize with white lettering for high visibility while clearing weapon
  • Center hole to help verify clear weapon by touch
  • About 80% stronger than 6061-T6 aluminum
