Overview

Built for 12-gauge 3-Gun use, this extended choke tube set gives shooters three stage-specific options in one package. The included tubes cover close, mid, and long-range needs, making it easier to match constriction to the target presentation without changing equipment between every shot. Knurled ends support quicker removal, and the tubes are laser marked for straightforward identification at a glance. It is intended for Browning Invector and Winchester platforms, so fitment should be checked before purchase.

Pros

Considerations & Trade-offs

  • 12 Gauge only, so it is limited to compatible 12-gauge setups and will not fit other gauges.
  • Designed for Browning Invector and Winchester, so compatibility should be confirmed before purchase.
  • This is a 3-piece set, which gives stage flexibility but means you are buying multiple tubes rather than a single all-purpose option.
  • The extended, knurled design is intended for easier removal, but it also adds a more prominent profile than a standard flush tube.
