Most Helpful Positive Review Very high quality product!
This product felt very sturdy out of the box. The lock up when extended is very tight and the retention when folded is tight enough to not just open but to be easily opened when you need to. My overall impression is very high
Most Helpful Negative Review What is it? What is it for?

by Jay, Verified Owner from FL, United States Written on February 16, 2025
I wanted to install a folding stock adapter to my AR pistol and settled on this one. Once I received it I could not install it because nowhere in OpticsPlanet website does it say that a second part is needed in order for this adapter to work. It makes no sense to sell only one have of an adapter. SMH, so beware.

Used this on a custom chassis stock.

by Dan, from OR, United States Written on March 10, 2020
This folding stock adapter allowed me to put a Magpul precision stock on a custom chassis rifle I am building. It locks up solid and gives a fantastic cheek weld. Being able to repeatedly put my cheek in the same spot is important and difficult with a folding stock. This product makes it easy and very repeatable.
Pros:
  • Repeatable
Cons:
  • None
Would recommend: Yes
