"This product fit well on my Spikes Tactical lower. It was nice finding a pistol buffer tube that was not designed for the Sig Brace, which I find to be horribly uncomfortable. The big problem I have with this is that the buffer and buffer spring that are included are for a carbine, not a pistol length AR with a pistol length gas system. Most AR pistols need a heavier buffer, usually an H2, (sometimes a heavier buffer spring will work) so I ended up spending more money to get that. I feel like a buffer tube designed for a pistol should have the parts you need for a pistol. I probably would have come out about even if I had bought all the parts separately. But you live and learn, and I guess now I have spare buffer for my carbine."
