Key points: PSA AK-102 5 56

  • The AK-102's firing pin broke on its first range trip; the creator chose not to send the rifle back to PSA, and Copperhead USA later replaced the pin.
  • On a later outing at Prevail Training Center in Flagstaff the rifle went dead again, and a look inside the bolt showed the replacement firing pin had also failed.
  • Copperhead USA installed an AK forced reset trigger while noting it usually advises against FRTs in PSA guns; the creator suspects the added wear plus suppressor back pressure, but does not rule out a bad parts batch.
  • A 100-yard group with AAC 77-grain OTMs through the Primary Arms optic printed high and strung vertically, and point of impact seemed to wander during earlier desert shooting with 55-grain ammunition.
  • The Primary Arms 3x prism is rated as an awkward middle ground: workable around 100 yards, slow up close, and hard to use on small targets at distance.
  • The verdict: 5.56 AKs make sense now that 7.62x39 and 5.45 cost more, but this PSA AK-102 is a range toy rather than a duty rifle until PSA tightens quality control.

Could be almost 2 years. Could be almost that long. So, the backstory about this, keep in mind I got to preface a lot of this by saying I'm actually a big fan of PSA products. They try and come up with really cool stuff […]
