Hello all. Hope all is well. I have another question which I believe is somewhat of a technical question. Last night I did an AR 15 lower build and when I installed the buffer tube Buffer Retaining Pin, I screwed the buffer tube right up to the nipple on the Retaining Pin leaving it a little tighter then my others. And when I went to test it, I put two rounds into a brand new short profile magazines which by the way, the spring action inside was very stiff, loading the rounds was unusually hard. I wanted to see if it would fire normally. When I pulled the trigger, the first round fired off, but the second round failed to chamber. My question is, would that be a result of winding the buffer tube tight on the Buffer Retaining Pin, or does that make a difference? On my other AR's I screwed the buffer tube in just enough to hold the retaining pin down, but on this one, I went another full screw. Please advise, thank you.
