MBX Buffer System

[Texaspaul]

Any one using the MBX buffer system ?  Does it work? any issues?

I’ve been using it with the heavy spring and have my gun short-stroked. Never an issue in well over two years.

I've used it in multiple setups and it works 100% - its a pretty simple mechanical system so there's not much to go wrong after you get the springs set up for your load.

I will say the Blitzkreig with a standard AR15 carbine spring, with a spacer, is what I prefer over the MBX system.
