Solid item - sturdy and paired with "Strike Industries AR Stock Stop" to make CA compliant on Kali9

by Ed, Verified Owner from CA, United States Written on August 18, 2022
Was hesitant to buy due to seeing another review saying it had sway/wobble. I installed it on my Kali 9 and it fit snugly. No sway, no jiggle or rattle (could be due to a pin install to prevent folding ability of trunion).

The 5.5mm pin fit nicely as well and stays in place. This stock adapter is really good to use if converting to a mil std tube. I wouldn't recommend it for someone looking to use it for a folding stock as it is rather square in shape and might not work well that way. Perfect for those of us in california though looking to convert to a buffer tube while staying compliant.

I had to be careful what fixed stock to get as some require a endplate that is between the receiver and buffer tube on most ARs. Given this tube isn't screwed in place to a receiver, this doesn't come with the end plate normally being used to secure it in place. As a result, I went with a "Strike Industries MOD-1" stock to have a semi AK look still and fixed it in place with the stock stop product they offer.
Pros:
  • metal
  • Exact Fit
  • Material
  • 6 adjustible points
Cons:
  • square shape limits folding ability
  • not compatible with a lot of fixed stocks due to missing endplate
Best Used for:
  • California
  • kali9

ok stock adapter

by Drew, from CO, United States Written on June 1, 2021
This adapter is a two piece design held together by two screws at the back of the hinge these screws walked out on me, and i had to remove the adapter from my firearm, and add some locktite and re torque them in place! The adapter also dosen't fit tightly with the receiver and has some wobble to it. The hinge is squared and dosen't allow for the stock to fold. over all a decent product easy to install my brace fits and locks to the tube well just wish they would hav4e done better with making sure it would not come loose and did not have any wobble.
Pros:
  • Stock/Brace fits nicely
Cons:
  • Screws need to be tighter, cant fold, has wobble to it.
Would recommend: Yes
