These Chokes features a bright stainless or matte finish and are made from 17-4 stainless and precision machined to produce a choke tube that patterns better than standard choke tubes. These choke tubes feature a 25% longer parallel section in the choke thus throwing more consistent patterns than conventional choke tubes. Each choke tube is knurled on the end to allow for quick and easy removal or installation. Each choke has the constriction lasered on the end for easy reference. These chokes are specifically for the Browning Invector, Mossberg Accu-Choke, Win-Choke Short 1.5".
