Adaptive Tactical is in the business of making box magazine-fed shotguns. The idea is straightforward: take a Mossberg 500 — or 590 or Maverick 88 — shotgun, replace the tube with a box magazine adapter, and double your capacity.
These kits are offered with five-round magazines which are compact and lightweight, but the draw for most shooters are the 10-round mags that Adaptive Tactical makes. With 11 shells on tap and another 10 more just a rock and lock away these kits convert common pump-action shotguns into lead-slinging behemoths.
