Hi,
Was just wondering. When testing the spring function of a magazine, it's difficult to tell whether spring tension is okay or not (apart from the really bad ones, of course).
Is there a simple test or can a simple testing device be developed for that purpose? As mag spring failure appears to be the numero uno cause for feeding problems, it's pretty important to check magazine spring pressure, I'd say.
Oh, and GT, I wouldn't worry too much. In order to drop to GM levels, you'd have to sell cardboard magbottoms
