OPTIMACHOKE HP CHOKE 12 GA - 2cm ex. Optimachoke HP choke tube (2cm exits the barrel when installed) with special DLC coating that guarantees better performance due to the friction reduction function and increasing resistance to climatic conditions
DIAMOND LIKE CARBON COATING (DLC) - It is a hydrocarbon coating that is generated through plasma deposition technique (reduction in the friction coefficient, greater wear resistance and an increase in hardness due to the rigidity of the created film)
INCREASED WALL THICKNESS - Increased wall thickness at the muzzle end of the choke tube where the greatest degree of choke constriction typically occurs and stresses are the highest without having to use the larger barrel contour
COMPATIBILITY - These steel choke tubes are compatible with DT11; 694; 1301 COMP PRO; A400XCEL A400 UPLAND; A400 XTREME PLUS; 686 Silver Pigeon I; all 12 Ga guns use OCHP (Optimachoke HP) chokes
ENGRAVED DETAILS - Every Beretta choke tube has information engraved on the tube to identify the manufacturer (PB), the constriction (F, IM, M, IC, CYL), the approval for steel shot use (SP) and the choke type
