Colt brand name spring

Posted by Michael on 3rd Apr 2020

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

Posted by Matt on 22nd Sep 2019

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?

I replaced my AR15 buffer spring with the Colt buffer spring and very happy with great quality and at a great price, will definitely be ordering more for future builds or to have as spares.

Good stuff!

Ended up buying some extra buffer springs just to have. Pricing was cheap, but the quality was good! +1 for Colt!
