I noticed on the MOE S&W M&P 15/22 they have built into the rear of the lover receiver a quick release swivel. I found on Amazon a swivel kit that contains,(2 swivel cups and 1 quick connect) for $12. You can drill out the lower receiver with a 1/2" bit and glue in the two cups, one on each side, then you can attach the single point to that. I plan on doing just that when my M&P 15/22 finds it way to my little hands this 9th of Nov.... can't wait..
