ALG AK recoil spring is a one of a kind design, it is manufactured from chrome silicon steel 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.

great spring tough to install.Review by goat9779
I found the same length issue as the first reviewer, and came to the conclusion of spring fade. I founnd the Alg spring difficult to reinstall, but due to the assemblies design not to anything Alg did. When installed in the weapon it was ferm and smooth pull to cock and return to closed bolt position. Have not fired yet, but I expect good result there also. Purchased two more from Ann Arbor Arms and also wanted to try the high out put hammer spring but they were unable to procure me one. Hope to eventually try the UL trigger also in the near future. Good smooth spring!
Question on lengthReview by Steven
Seems like a solid product!!!! Nice finish and it feels very strong but I noticed this spring is longer than the one in my weapon already...is this good? Is that what a new spring is suppose to be like? Maybe mine is just older and worn?? I have no idea but I'm sure it is fine
** ALG Defense: Yes this is normal for this type of spring.**
