ATI Aluminum Fluted Magazine Extensions

    ATI has developed a nice looking aluminum fluted magazine extension that will be available for a range of shotguns. Three different end caps are available. There is a regular flat cap, a flat cap with a swivel stud and a spiked stand-off cap. The stand-off cap would be useful for law enforcement officers with short barreled shotguns where the magazine extension will extend further than the barrel.

    The press release …

    Advanced Technology International® (ATI), the leading manufacturer in gun stocks and firearm accessories is now shipping aluminum fluted magazine extensions for select Remington, Winchester, and CZ 12 gauge shotguns.

    ATI’s new magazine extensions will be offered with three different end caps for the customer to choose from. The three style options include a standard flat cap, swivel stud cap, and stand-off cap, with each providing a different style or unique combat option.

    ”The fluted magazine extensions will be offered in both 7 and 8-shot models which add 2 and 3 shells respectively,” said Jon Shaffer, Director of Business Development.

    Shaffer later added that the extensions were uniquely engineered to match the outside diameter of the shotgun’s barrel lug. Designing the extensions in this way was key for ATI to make their aftermarket accessory flow seamlessly with the firearm.

    The magazine extensions are constructed of Military Type III anodized 6061 T6 aluminum, and are covered by a limited lifetime warranty like all of ATI’s U.S. made products.
