LEO® Telescoping Stock Adapter For Moss 500/590A1/Mav88 (12-GA And 20-GA)
Use Mesa Tactical’s collapsible stock kits and adapters to install AR-15 adjustable buttstocks and pistol grips onto the venerable Mossberg 500, Remington 870 and Beretta 1301 shotgun platforms for the ultimate in tactical shotgun configuration performance.
The LEO aluminum adapter kits include everything necessary to retrofit Remington or Mossberg pump shotguns with most AR-15 style stocks and pistol grips. Our adapter kits allow customers to add their own AR-15 stock assemblies as desired. LEO® telescoping stock adapters, feature a stock elevation about an inch lower than the High-tube adapters and so don’t require sighting or aiming aids.
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 LEO stock adapters are investment cast aircraft aluminum. They are then CNC machined and anodized with a Type III Class 2 Mil-spec finish. To meet the requirements of professional operators as well as competitors, we offer two lines of telescoping stock systems: High-tube® and LEO.
The LEO adapter 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 push-button sling swivels, and Remington 870 LEO adapters can accept stamped steel sling loop and hook loops.
These adapters are available in two types of kits, adapter kits or complete stock kits.

This adapter is really nice. Very well made. Aluminum is nicely finished. Easy to install- took probably 5 minutes total. I put it on a Mossberg 590 12ga. shockwave. Will be adding a SB pistol brace to it in the near future. Contemplating getting one for my Mossberg 500. I highly recommend this product for a solid upgrade!
Item is solidly built, I like the fact that it’s made of aluminum and not plastic like some of the competitor products. Install was pretty easy, though some minor fitting was required around the rear of the trigger group. A needle file made quick work of this, providing a tight fit. I installed it with a common rifle accessory company’s AR butt stock (they’re known for their 30 round magazines). I used a common AR buffer tube and nut. My eye lines up perfectly with my red dot and the option to completely collapse the stock is a nice perk. I installed a standard AR pistol grip that I had laying around, but will be looking for a zero angle one to replace it. This will help keep my elbow tucked in when I’m at “Low Ready.” I installed the item on a Mossberg 590 A1 and am very happy with how it turned out.
Well designed product.The part was not available for shipment and I had to call to find that information out.The staff was very helpful ....A+.Minor fitting was required to make the part fit my gun but took less than 10 minutes to complete.I would recommend a reduced angle grip and be sure to get one without the beaver tail as they would not fit this model.
Very good quality made, all metal product. Easily installed.
this is the my second purchase of this item and it works great on both shotguns.
Very sturdy , very solid product, installing it on my mossberg 88.
Tried the Ergo, while it works, I wanted something a bit more robust and with QD points on it. The Mesa Tactical fit the bill, expensive but quality! Installed on my Shockwave in minutes.
