I finally joined this forum today after a few months of perusing around and I came up with a question I was hoping to get answered. I'm slowly building my AR and I'm down to the last few pieces. I went with a semi auto BCG because it was in stock at a decent price. I'm now looking for a buffer. So (finally) here's my question.. Which buffer would be ideal for a semi auto BCG? I know it's only a tinyyy bit lighter and I'm sure most any buffer would be fine, but is there an ideal weight I should look for? Thanks in advance.
