Frequently Asked Questions

What were the main issues encountered with the Resilient Putnik suppressor on the PSA Krink?

The primary issue was the suppressor backing out and becoming loose when direct-threaded onto firearms. This was resolved by using a KeyMo adapter system with a compatible muzzle brake, ensuring a more secure and consistent attachment.

How did the PSA Krink perform in terms of reliability after 2,000 rounds, especially when suppressed?

The PSA Krink demonstrated excellent reliability, with zero failures to feed, fire, or eject, even after 2,000 rounds and predominantly suppressed use. This was attributed in part to chamber polishing performed by the owner.

What were the accuracy results for the PSA Krink at 50 yards?

Bench rest accuracy at 50 yards was disappointing. Using Winchester M193 55-grain ammo, groups were around 5 inches, and with Frontier 75-grain match bullets, groups were approximately 4 inches, suggesting limitations for precision shooting.

Which magazines were found to be compatible with the PSA Krink?

The PSA Krink reliably functioned with PSA 5.56 AK magazines and Ballistic Advantage magazines fitted with Pod Arms followers. However, AC Unity 5.56 AK magazines presented significant latching issues.
