BRAIN Chokes are offered in two versions: HUNTING and COMPETITION.

The difference between HUNTING and COMPETITION inner profile design is very slight. Be sure that you can use both types with equally perfect results regardless the intended use. Differences in performance between HUNTING and COMPETITION choke tubes of the same constriction are hardly distinct, no matter if you shoot heavy field loads or light target ones.

Constrictions in mm and inches may sligthly vary according the barell bores of each shotgun manufacturer.

Constrictions are Laser marked on external part so there is no need to unscrew choke to check installed constriction.

​All HUNTING and COMPETITION choke tubes are available in three colours of the external ceramic coating and NATURAL:
