My Aero m5 has a Wilson combat tactical hunter 18” 308 barrel. Superlative arms AGB. Wilson combat 308 rifle has tube Re-A5 buffer tube, h3 ar15 buffer, 308 rifle spring. Toolcraft dual extractor bcg. I’m having issue fte and trying to double feed rounds out of the magazine. I try tinkering with the agb and I haven’t found a sweet spot of functionality. Are there any tips to get it to fucntion?
