Buttstock Collapsible Stock Change?

[lshel]

If you want to change to a Magpul CTR buttstock, do you have to change buffer tube and other parts or are these common and just slip new buttstock on? I have a SW commerical 6 position collapsible buttstock on my M&P10 and want to change to the CTR style. How too?

The buffer tube comes in two sizes. Mil-Spec and commercial. The CTR also comes like this. This is due to the slant on the rear of the commercial tube and different diameter size. Hence you must buy a CTR commercial stock version or change out the tube.

Thanks R1100R. I thought just add the correct buttstock type, but I wasn't sure. The trouble with AR's is there are too many available accessories. Deminishes the cash on hand.
