The concept behind the telescoping stock system is simple:
the shotgun stock is replaced by an adapter, which attaches to the rear end of
the shotgun’s receiver and it, in turn, mimics the rear end of an AR- 15 lower
receiver, into which an AR-15 receiver extension tube can be threaded. The
AR-15 telescoping stock and pistol grip can then be reliably attached. Our
stock adapters are investment cast aircraft aluminum, which are then CNC
machined and anodized with a Type III Class 2 mil-spec finish. The ITT Enidine
recoil buffer is also CNC machined from 6061-T6 aluminum and meets the
stringent standards of military and law enforcement users. To meet the
divergent requirements of professional operators, we offer three lines of
telescoping stock systems: High-tube™, Low-tube™ and LEO.
The LEO adapter, manufactured for the Remington 870 and
Mossberg 500/590, is our most basic, best-selling model, and features an
optimal stock elevation allowing the use of iron sights or even the bead sight.
All LEO adapters accept optional pushbutton sling swivels, and Remington 870
LEO adapters can accept stamped steel sling loop and hook loops.
The LEO’s low cost and streamlined appearance make it the
best choice for agencies looking for a simple, reliable telescoping stock at an
affordable price. Our High-tube and Low-tube adapters, with mounting points for
Picatinny rails, SureShell shotshell carriers and other accessories, are
specialized adapters for unusual law enforcement applications or competition.
Accessory mounting points on the sides of the High-tube and Low-tube aluminum
Picatinny rails, sling mounts or Mesa Tactical shell
carriers, and are fitted with HeliCoil stainless steel thread inserts for
strength and long life. Low-tube adapters feature the same low stock elevation
as the LEO adapters; Hightube adapters share the proportions of an AR-15, such
as an elevated stock height, and include a Picatinny rail on which to mount
optics (note: High-tube adapters cannot be used without rail-mounted sights of
Our aluminum adapter kits include everything necessary to
retrofit Remington or Mossberg pump shotguns with most AR-15 style stocks and
Our adapter kits allow customers to add their own AR-15
stock assemblies as desired. Our complete stock kits are more comprehensive.
They include the aluminum AR adapter; Hogue rubber
overmolded grip; US-made five-position M4 SOPMOD style telescoping stock
assembly; and all necessary assembly hardware and instructions.
The High-tube stock kits also include a receiver-length top
Picatinny rail. A push-button sling swivel is included with all stock kits.
