Since the last 2 range trips I've had FTE's with my M40A1 I'm off today to get the final diagnosis.
Gun is cleaned and lubed
Mags are cleaned out and numbered.
pad and pen in range bag
500 rounds of WWB
Going to load each magazine to capacity
fire each one and mark down if there was a problem
If one magazine gives me a problem, I will re test that magazine
If multi magazines are an issue, I will swap parts (recoil spring & extractor) from my M
If problem seems to be one magazine (I hope) then that mag will be replaced.
Any other suggestions for a diagnosis ?
