After watching some videos on youtube, the creative juices in my head started stirring and I was wondering, how feasible would it be to put a LR300 style Stock on the M&P15-22? As great as the MOE stock is, I think it would be a little cooler to have the Folding stock on it.

The plan is to chop down the polymer buffer tube enough to be able to fit the stock onto the rifle. The Airsoft LR300 stock would have a screw going through the middle of it, so maybe I could drill a hole right through the back of the receiver and screw the stock on using a nut.

Since the rifle doesn't need a receiver extension to operate, I'm wondering if this'll work. I know it's still legal as a rifle, however I wanted to get your guys' opinions on this plan.
