Excellent video. I've researched this heavily, with calipers in hand, and multiple receivers. This video gets it right. The tang heights for DPMS High and Low are widely misreported, and the terminology used on message boards and even by plenty of manufacturers is incorrect. This video is the most factually correct and condensed description I've seen yet. The visuals for how the patters line up are super helpful too. Great job!
I bought a Receiver Set from Palmetto State Armory 308 build and I need to know if Samson Manufacturing makes a handguard and barrel nut for this upper receiver???
