High-Tube® Telescoping Stock Adapter For Rem 870 (12-GA, No Rail)
Our High-tube adapters have a comb height equivalent to an AR-15 and require a Picatinny optics rail (sold separately). 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 complete stock kits include an optional 9 1/2" inch top Picatinny optics rail.
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.
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 mil-spec receiver buffer tube. The AR-15 collapsible stock and pistol grip can then be reliably attached to the shotgun. 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.
No gunsmithing is required to install. Minor fitting of fasteners may be necessary.
High-tube® Telescoping Stock Adapters and Conversion Kits
These adapters are available in two types of kits, adapter kits or complete stock kits.

I was not provided with the proper hex head bolt for attaching the adapter to my 870. The provided bolt was to large. I also did not receive the spacer blank that is needed between the adapter and 870. Nor were the plates that cover the picatinny rail accessory bolt holes located on each side. In the end I had to modify the adapter to utilize a shorter hex head bolt that was the proper size and thread pattern. A hex head size that hardware stores do not carry by the way. I had waited long enough to receive the unit via mail and I was not going to wait for the proper bolt to be shipped. So I spent over a hundred dollars on a part that I had to machine further to make the part usable. I love the part and what it does to my shot gun, however I had to pay a premium price for a part that I had to modify due to lack of proper bolt and missing items needed to simply install the part.
Great product and fitment!! Shipping on the other hand not very good!! Took 5 sec to take my money.....took 15 min to get moved into awaiting shipment......took 6 days to move from awaiting shipment to product shipped......took five days after that for the product to show up at my door.
Just installed on my Remington 870 Super Mag, and went on with little effort. only two things i had issues with where the adapter plate doesnt fit well (i am not sure if there is a size variation of a Remington 870 and a 870 S) but the plate jingles and fits sloppily so i cannot imagine what its supposed to do in that state...also I wasn't thrilled with the "set the nut in the adapter" and threat the grip into it...it does work, don't get me wrong, but it wasn't something that "thrilled" me, perhaps one more machine process and make a nut shaped indent. overall i like the finish and the fit (minus plate) and will show all my friends
Works like a dream. Seriously the best adapter on the market. Worth every penny.
