I have the PSA AK556 that takes AR Mags. Accurate and fun to shoot. Issue I’m having however is during consistent fire, rapid shots, I get constant double feeds. Any idea how to fix?
A KNS piston might help.
How so?
Start with the magazine, try using a 5 or 10 round mag if your using a full 30. Try a metal mag if your using polymer. Try using a new mag if yours is worn. Look at the mag feed lips, if metal try changing their profile.
