I got this stock because I've never gotten a satisfactory cheek weld with a collapsible stock. Problem solved, a terrific improvement. I mounted mine on a S&W 15-22. It required filing a small notch in the receiver extension. A 1/4" rat tail file made quick work of this. No modification at all is required for use on an AR15 carbine buffer tube.
Pros: Well made, easy to install, good value
