Most Helpful Positive Review works great!
Got this for a gen 2 kriss vector. Very solid piece, great lock up. Push button works good. Also not very long so as not to add to much to the length of pull. This product only took about 5 min to install. Comes with 2 different thread depth mounts. I would recommend this item.
Most Helpful Negative Review Does not work with an AR-15 with a buffer tube, only works on a bolt action rifle.
I really wish they were more clear about the compatibility of the folding stock adapter and that it DOES NOT work with an AR style rifle or pistol. You cannot have a buffer and spring with the MDT folding stock adapter, there's no pass through, it's solid. Not sure why it's advertised as an AR foldi...

MDT Folder

by Sgtmac168, Verified Owner from CO, United States Written on October 19, 2025
The MDT fits perfect and helps make your rifle a bit shorter for easy transport. It's easy to install as long as you have the parts. It's a little bit stiff opening in the beginning but is getting easier with use.

great product

by scottyL, Verified Owner from AR, United States Written on July 18, 2025
I got this because I had to remove cheek riser and butt pad from chassis every time I cleaned. Not any more. Worth every penny!

MDT-1 way stock adapter

by MAC, Verified Owner from NC, United States Written on July 2, 2025
Item is as described. Locks up solid when set in place. Storing while folded is the best use for this product. The 2 way lock would be the better choice for any other activity.
Best Used for:
  • Storage

Few folding adaptors for chassis systems

by Fishnhat, Verified Owner from OH, United States Written on May 15, 2025
Lots of brands build folding adaptors for ar platforms. Only a few build aftermarket adapters for chassis. This is what you want if you want a full length ar stock on and outlier chassis. Both a pro and con is that the hinge is STIFF. It was hard to close for mounting but it won't just swing closed on its own.
Pros:
  • Still hinge
Cons:
  • None
Best Used for:
  • Bolt action chassis systems
Would recommend: Yes

solid, sturdy, and exactly what I needed

by bubba, Verified Owner from TX, United States Written on April 15, 2025
I built a bolt action setup, on a Savage 110 receiver, a chassis and ar stock.
Other folding stock adapters made for an ar receiver were too tall and interfered with the grip.
they offer this one in three configurations, rifle to rifle, tall to tall, carbine to rifle, tube height to full ar receiver height, and carbine to carbine, tube height to tube height. I used the carbine to carbine ones and would have used the cabine to rifle one if i was using a different stock.
It feels solid, folds smoothly, and locks without any rattle.
Better feeling and looking than I expected.
10/10 rating, thanks
Pros:
  • silent and ease of movement.
  • Solid well built
  • large buttons for function
Cons:
  • Not cheap but worth every penny.
Best Used for:
  • ar buffer tube style chassis

Used to add a folding arm brace to PLR-16

by Mark, Verified Owner from MO, United States Written on February 6, 2025
After trying a few other folding adapters to add a folding arm brace to a PLR-16, I tried this one. Worked almost out of the box, but had to add two washers for spacing. Without the washers the screw would bottom out on the PLR-16 tube.

Only real complaint is that it is really tough to fold. It locks nicely, easy to unlock, it is just that the folding is quite tough. Hoping that after awhile it will loosen up.

by Old MP vet, Verified Owner from KS, United States Written on September 9, 2024
Awesome little gadget! I rebuilt my 10/22 with an AR type buffer tube & stock. This turns it into a folder for more compact travel. Easy to install, easy to use.
Pros:
  • Sturdy, locks tight
Cons:
  • Does not work for AR that uses buffer spring
Best Used for:
  • Ruger 10/22 converter chassis

MDT 1-Way Locking Folding Stock Adapter

by cdplummer, Verified Owner from TN, United States Written on August 10, 2024
This is a great folding stock adapter. I purchased the carbine to carbine design. It's extremely well make and very rigid when locked into position. I would highly recommend this product.
