ALG Defense has been slowly adding more SKUs to their lineup in the last year with a special eye towards AK owners. Late in 2015, they debuted a low cost AK trigger replacement, and the 2016 SHOT show saw them bring several new springs to the market. One of those is a new recoil spring designed as a drop-in replacement for the one that came from the factory . . .
From ALG’s website:
ALG AK recoil spring is a one of a kind design, it is manufactured from chrome silicon steel to resist impact shock and relaxation. The 2 to 3 dead coils in the center change the natural frequency of the spring, which prevents harmonics from damaging the spring and reducing its free length.
There’s a lot I don’t like about AKs, but I’ve never found myself hating on their recoil springs…probably because I’ve never shot one long enough to notice. If you have an AK with spring issues, ALG has the fix for what ails you, and at $12, it seems like a cheap fix.
