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.
There are two lines of Mesa Tactical telescoping stock adapters:
1. High-tube® telescoping stock adapters, that require the use of railmounted optics.
2. LEO® telescoping stock adapters, which feature a stock elevation about an inch lower than the High-tube adapters and so don't require sighting or aiming aids.
These adapters are available in two types of kits, adapter kits or complete stock kits.
The heart of the Mesa Tactical Telescoping Stock Conversion Kit is the stock adapter. The stock adapters are investment cast aircraft grade aluminum, CNC machined and powdercoated black with a tough, chemical resistant finish.
Our 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. No gunsmithing is required to install. Minor fitting of fasteners may be necessary.
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.
Stock kits additionally include an M4 Carbine style telescoping buttstock assembly, a Hogue rubber overmolded pistol grip, a stamped steel stock wrench and a push-button sling swivel. A slip-on rubber butt pad for the M4 Carbine buttstock is available separately.
