A very simple upgrade - Wilson Combat Bolt Upgrade Kit

I buy these upgrade kits for all of my ARs. I have a stack of them for both AR15 and AR10. I add a few to my cart whenever I'm buying something small and I need to get to a certain amount for shipping reasons. I cannot say that it has ever made a noticeable change to the rifle, but I get peace of mind knowing that gas will never randomly leak though. For the price, why not upgrade your bolt with this kit? If you don't have the tools, you don't have to upgrade the springs. It's still worth it just to upgrade the gas rings. You can remove and replace your gas rings with simple pick or a pocket knife.
