Thank you for such valuable feedback! I will update you if and when I find a system.

My first thread and my first 308 Armalite build. So a few weeks ago I purchased a Matrix Aerospace upper and lower. Having build many AR15s I figured it wouldn't be much different. So I have a few questions. Is the only difference the magazine well dpms/ar10 and the rail height on the upper? I want to build a 4 position, piston driven rifle and now I'm too afraid to buy anything but the handguard in case it's the wrong type. A little push in the right direction would be much appreciated!

For me... It was a trade. I was not really looking to get into another caliber. And a guy wanted my AR15 and was offering a socom 16.....it was love at first shot. Now I'm building a Ruger762 clone.
