Carlson's Black Cloud Browning Invector Plus Long Range Choke Tube

These choke tubes are specifically designed to get the most performance from Federal's Black Cloud Ammunition, but perform extremely well with other steel shotshells. The Long Range model can be used with all steel shot sized except T and F (but should not be used with any steel shot loads faster than 1550 fps). The Mid-Range model can be used with all steel shot sizes.
