Back in Stock: High-tube Recoil Stock Kit for Shotguns


There are two lines of Mesa Tactical telescoping stock adapters:

  1. High-tube® telescoping stock adapters, that require the use of rail mounted 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. This part is investment cast and machined A-356 T6 aluminum and replaces the factory stock. The rear and lower faces of the stock adapter resemble the back of an AR-15 lower receiver, so it can accept most stocks and grips made for the AR-15.

The High-tube Adapters mimic the geometry of an AR-15 rifle, which means they can accept any buttstock or grip made for the AR-15. This also means the stock elevation is too high to use receiver- or barrel-mounted sighting systems. This is why High-tube adapter kits usually include a Picatinny scope rail, so that an optical sighting system can be mounted on the weapon.

Note that High-tube adapters must be used with rail-mounted optics or back-up sights, or at least some kind of sighting system positioned high on the receiver.


Telescoping stock adapter or adapter and rail kits include the stock adapter, Picatinny scope rail (if a High-tube kit) and all required hardware. They are for operators who wish to install their own stocks and grips.

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.

Recoil Stock Kits include the Crosshair Hydraulic Recoil Buffer, which takes the place of the receiver extension tube, converting the AR-15 telescoping stock into a recoil-buffered stock assembly without further modification. Recoil stock kit versions are available for both LEO® and High-tube® telescoping stock systems, or the recoil buffer can be purchased separately. The recoil buffer accepts mil-spec dimensioned buttstocks. The Crosshair Hydraulic Recoil Buffer is CNC machined from 6061-T6 aluminum and meets the stringent standards of military and law enforcement users. No gunsmithing is required for installation.

The Crosshair hydraulic recoil buffer is built to perfection and to perform at the highest level. The Crosshair buffer tube reduces felt recoil by up to 70% while improving accuracy. This advance in performance is achieved by increasing the recoil event impulse time through the use of adaptive hydraulic technology. Decreased felt recoil allows for follow up shots to be aimed quickly and precisely.
