Jmac Customs with another quality part

by T-Doggfreshmofo, Verified Owner from OH, United States Written on March 26, 2025
Fits my Nak9 perfectly. No wobble. Threaded all the way to last turn and detent locks in.

Doesn't fit KP9

by Sunny Singh, Verified Owner from TX, United States Written on August 15, 2023
Looks and finish is great, but on KP9 it doesn't lock-in with the detent pin. There's lot of play, it doesn't stay in place moves freely, not recommended for KUSA KP9.
Its advertised for Kalashnikov firearms but doesn't fit on KUSA-KP9, really disappointed with the purchase, sent it back.
Pros:
  • Looks and feels great
Cons:
  • doesnt lock in with detent pin
Would recommend: No
