Chamber Chiller BETA-60 USB is a well developed barrel cooler for rifles with minimum port opening 58mm wide and 15.5mm tall. BETA-60 USB is ideal for rifle cartridge rims measuring 11.9-15.0 mm. It works best in bolt guns but may also fit some semi-automatic weapons.

Please check your port clearance before ordering

Please Note:

The Chamber Chiller nozzle should only touch the outside edge of your chamber. The nozzle should not be inserted all of the way into the chamber.
