Mesa Tactical's High-tube adapters have a comb height equivalent to an AR-15 and require an optics rail (included). These specialized adapters are for certain law enforcement applications or competition. High tube adapters allow proper cheek weld and eye alignment with popular optics such as an ACOG or Leupold CQT and others. High-tube adapters and stock kits include nine inch or 24 inch top Picatinny optics rails. While the 9.50 inch rails can optionally be secured to the shotgun receiver as well as the stock adapter, the 24 inch rails are anchored at the front by a clamp.
Use Mesa Tactical’s collapsible stock kits and adapters to install AR-15 adjustable buttstocks and pistol grips onto the venerable Remington 870 shotgun platforms for the ultimate in tactical shotgun configuration performance. Equipped with the Mesa Tactical stock adapter, the shotguns have an adjustable length-of-pull to perfectly fit to the shooter’s stature or equipment, such as body armor; feature handling characteristics similar to the ubiquitous AR-15; are more compact for transport and storage; and are more controllable due to the pistol grip configuration.
The concept is simple: the shotgun stock is replaced by an adapter that mimics the stock attachment point of an AR-15 lower receiver. This adapter accepts an AR-15 receiver buffer tube. The AR-15 collapsible stock and pistol grip can then be reliably attached to the shotgun. The stock adapters are investment cast aircraft grade aluminum, CNC machined and powdercoated black with a tough, chemical resistant finish
