PS Professor Nick's Review of Presma AR Pistol Stabilizing Fin

I bought this to go on a KAK Mini pistol buffer tube I was using in a “spare parts” build. Without spending much, I got something that was damned near immovable and, because of the clamping system, didn't depend on having a set screw directly in contact with the receiver extension.
Pros:
  • Clamping system rather than a set screw.
  • Good quality fasteners that I was able to give a solid torque without concern for stripping them.
Cons:
  • Once you set it it, you are going to have to work if you need to adjust it.
Best Used for:
  • Real pistol builds that are not just SBRs hiding behind a legal fiction.
