working in the field with a unit that has poor/older m4 30 rd mags, looking for the correct spring length and feed lip dist. Also is there a way to test 30 rd mag spring tension with a weight or something? thought I saw a test for this years ago. thanks very much.

Hunter,
Check on the availability of the new "Magazine Feed Lip Gauge"......http://peosoldier.armylive.dodlive.mil/2009/12/14/armys-improved-magazine-increases-weapons-reliability-%E2%80%9Ctan-is-the-plan%E2%80%9D-for-the-new-magazine/
As far as mag spring specs and testing goes, unfortunately I do not have that information.
ETA: Where are you currently deployed?
