Considerations & Trade-offs

  • Designed specifically for Mossberg 500/590 and Maverick 88 12 gauge pump shotguns, so it is not a universal stock option.
  • The adjustable length-of-pull adds fit flexibility, but it also introduces more moving parts than a fixed stock.
  • The pistol grip configuration may suit some shooters well, but it changes the shotgun’s handling and shoulder feel compared with a traditional stock.
  • Polymer construction keeps the design lightweight and practical, though it may not appeal to hunters who prefer a more traditional material look and feel.
