Is JD Machine's 308 still going off of DPMS's old rail height spec? I know a few years back DPMS went to a different (lower) height and made a bit of a mess of things.

If you tell me where to measure, I can check.

I'm also selling a couple in Equipment Exchange here.

The easiest way is to measure  the thickness of the rail between the charging handle cut-out, and the top of the rail.

0.225" PM if interested on taking one off my hands. Either way, I do not mind measuring anything else you would like me to. Please PM though as I cannot track posts.

JD Machine uppers are the standard (higher) height.
