TacStar Magazine Extension Features The TacStar Magazine Extension adds five rounds of capacity over the factory tube when using 2 3/4 inch shells giving Remington 870 owners significantly more rounds on tap before a reload is needed. Machined from 6061 aluminum the extension tube is both lightweight and strong enough to withstand the repeated recoil and handling a shotgun magazine tube experiences. The matte black anodized finish resists wear and corrosion keeping the extension looking clean through extended use. Because both ends of the tube share the same thread pattern the extension can be reversed to relocate the magazine or barrel clamp recess for different mounting configurations. Each extension includes a long magazine spring that can be trimmed to the shooter s desired length allowing fine tuning of feeding reliability and overall function. A high visibility follower is also included improving both cycling performance and making it easier to spot the follower at the loading port during a reload. Capacity Increase: +5 Rounds reflects the core value this part adds to a Remington 870 shotgun s factory magazine. This extension is a straightforward way to increase a defensive or competition shotgun s round count available for sale at GrabAGun.
