Turn the Ar-15 into a sub gauge shotgun! Our upper fires .410 shot shells and fits on 5.56 or .223 Ar-15 lowers. Installation is identical to any other upper just drop on your factory lower, use the included bolt carrier group, charging handle, buffer and spring then add the 10 round .410 magazine and that’s all it takes to get started. Be sure to check ammo before buying as we have found substantial fluctuations in the over all case length. If you can load it in the mag it will feed. 2.30 inch or less case length worked well in testing. We recommend shooting heavier loads to get your upper broken in. The uppers we tested only needed less than a box of heavy loads before they flawlessly shot the low brass bird shot.
