Took my M1 garand shooting today. Just replaced the clip latch spring , and op rod spring. Eight round clip shot great with no problems However my five round enbloc clip did not want to "catch" when inserted. Was able to hold the clip down and chamber the round and then it shot fine, shooting all five rounds and then the clip ejected. Can anyone give an explanation as to why my rifle doesn't like the Phibr as to why my rifle doesn't like the 5 round clip?
