This choke features a constriction designed specifically to optimize patterns with large and small loads alike. This choke will extended about 1" out of the barrel and has a black finish. Machined out of 17-4 heat treated material this choke can be used with Lead, Steel, and Hevi-Shot loads. *Note- this choke cannot be used with any steel shot larger than BB or with any steel shot faster than 1550 FPS.
