Action spring for AR15, M4 adjustable stocks. Made to M4A1 Mil-Spec specifications.
Nicely made seems really strong think it'll work great.
Quality product that is quiet compared to others I have used. I don’t get that weird “twang” sound I have gotten with other springs.
Does what it says. very affordable too.
This is the spring is unbelievably and exceptionally springy. It does exactly what it is designed to do. The only thing this spring could do better is make my coffee in the morning.
Rebarreled a 5.56 to a 300BLK, old +1 spring caused short strokes on subsonic ammo. Standard spring cured the problem.
It looks much better compare to other major manufactures.
What can I say it's a buffer spring and it works
Top quality!
Quality and reliability.
