Foxtrot mike 9mm upper on a rock river lower with Hahn mag block 5.4 oz carbine buffer spring assembly in both with spikes buffer spacer both setup for modified 25 rd uzi mags that also have +10 Taylor freelance extensions i originally used Wolf extra power springs from Taylor that we’re supposed to run better than stock uzi. I am am having a jam on my 2nd shot on a full mag is the mag spring too strong/tight? issue with buffer weight? Power of buffer spring? helpful suggestions much appreciated Link to comment Share on other sites More sharing options...
