High-Tube® Telescoping Stock Adapter And Rail Kit For Rem 870 (12-GA, 9 In Rail)
Mesa Tactical's High-tube telescoping stock adapter and rail kit adapts AR-15 telescoping stocks, grips and accessories to Remington 870 and Mossberg 500/590 shotguns.
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. High-tube adapters and stock kits include a 9 1/2 inch top Picatinny optics rails. The 9 1/2 inch rails can optionally be secured to the shotgun receiver as well as the stock adapter. No gunsmithing is required to install. Minor fitting of fasteners may be necessary.
With the High-tube AR Stock Adapter and Rail system, military, law enforcement and civilian shooters can mount almost any AR-15 stocks and grips on to their favorite pump-action shotguns, supporting a variety of tactical applications. Optional Picatinny rails can be employed to mount tactical optics and accessories.
The heart of the Mesa Tactical High-tube AR Stock Adapter and Rail system is the receiver adapter, made from investment cast T6 aluminum with a hard anodized finish. Receiver adapters will be available for Remington 870 and Mossberg 500 pump-action shotguns. The High-tube adapter accepts any AR-15 style grip and any AR-15 style buttstock. The receiver adapters are drilled and tapped on three sides for Picatinny accessory rails, sling swivel studs, or other accessories.
TELESCOPING STOCK AND ADAPTER KITS
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 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.
Complete stock kits additionally include an M4 Carbine style telescoping buttstock assembly, an ERGO AR pistol grip, a stamped steel stock wrench and a push-button sling swivel. A Limbsaver® slip-on rubber butt pad for the M4 Carbine buttstock is available separately.
All Mesa Tactical High-tube AR Stock Adapter and Grip System components can be installed in minutes with household tools. No gunsmithing or fitting is required.
