Much better than the KNS perma-pin

by c ross, Verified Owner from MI, United States Written on August 7, 2025
Originally bought the KNS model, but the tines/tabs on the kns version don't stay sprung after the first install and perpetually fall out. No such issue with the tacfire permanent retainer pin. This model though is a great purchase and no problems after 2-3 years.
Pros:
  • Springy tabs
Cons:
  • None
Best Used for:
  • ar 15
Would recommend: Yes

Great aftermarket item for AR

by Dennis Seymour, Verified Owner from OH, United States Written on September 27, 2023
Easier to use for those with dexterity issues. With multiple ARs and multiple BCGs nice to have retainer for firing pin that is quicker to use. Still have to see how it holds up at the range. I am trying it on AR build, then will try Ruger AR-556 and EPC9 build.
