Mine is the standard, adjustable stock. I've looked at all those listed at Midway. Looked at Pachmayer's web site as well. Hard to make a choice just based on brief description. I'd prefer one that slips over existing stock or could use existing screw holes.

Any recommendations?

Same as mine----Tapco T6 from Midway----$11

I have an M&P 10 and use this one. http://www.midwayusa.com/produ...cm_vc=ProductFinding
I got mine at Sportsman's Warehouse.
