Most Helpful Positive Review perfect from my 22lr AR build
Works perfect and does not allow the bcg to move. I installed on my 22lr build for more pistol look and will attach a folding stock later on. Took to the range and runs flawlessly. Could not ask for a better product.

Does not work with the Sig Rattler

by Klugey1, Verified Owner from NC, United States Written on November 13, 2022
The MCX Sig Rattler requires the bolt and piston system to retract about 3/4” into the back of the lower receiver (into back edge of the buffer tube threading). This KNS product screws into the buffer tube threading so that it is flush with the FRONT of the buffer tube threading. It does not allow the bolt to go back far enough to pick up a round. Buy the Sig oem adapter for this and see the difference.
Pros:
  • Looks nice
Cons:
  • None
Would recommend: No

good for what it is

by Dave Winters, Verified Owner from PA, United States Written on October 14, 2021
It’s easy enough to install onto a standard lower. The flange version stops the real takedown pin from coming out. I used it to install a sig folding stock on a 22lr dedicated upper. This parts kit worked perfect with the sig 1919 adapter.
Would recommend: Yes

Perfect for what I was looking for.

by Phoenix, from AZ, United States Written on September 23, 2020
Works exactly as described. Expected nothing less. It attaches to the back end of a pistol for a folding brace to be able to be attached. I had one of those laying around and this helped me save money so I didn’t need to buy another type of brace.
Would recommend: Yes
