Must have for suppressed ak. - ALG Defense AK Recoil Spring

I have a few AK / AKMs that I run suppressors on and this recoil spring is the only upgrade you'll need to fix reliability issues, rather than bothering with gas regulators, ports, or ammo selection. After dropping this spring in my guns cycle perfectly with all types of ammo I've fed them. Highly recommend, especially as a first step if you're trying to tune you gun / slow down bolt return travel.
