Just reaching out for some help with my AR pcc feeding issues i have 2 guns. 1. Rock river 9mm dedicated upper with rock river mag insert 2. 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

Does the Green dot on the Firedot BDC show up well on sunny days? Is it larger than the red dot in the Firedot circle? thanks.......

I shoot 3gun in the Northeast so 200-300 yds is maximum course distance (most are 100-200 yds). I'm interested in either the Leupold VX 1-6 with the CMR2 or the new BDC reticle with Green center dot. Does anyone have experience with either? Recommendations? Thank you in advance for your advice -- Tom
