Colt
It’s a standard colt action spring. It is what it is. Works. Replace as needed.

Ar buffer spring
Fast turn around quick and easy.
-
Colt brand name spring
Colt brand named buffer spring. The buffer spring is probably the cause of almost all issues with any AR type rifle. They need replaced often(every 5k to 10k). There are many out there but so cheap, spend the extra dollar and get the colt brand name.

Perfect
Fit and function is perfect. Will be purchasing again for my next build.

Stout spring
Sure. You could pay 3.99 for a spring of questionable quality. But why not go with a solid brand and pay a few bucks more?
