Been building custom AR’15’s for many years, and been using the usual six position collapsible’s , until I found these stocks. Let me tell ya 5 star product as far as construction goes , fit , and looks can’t beat em. Was at the range zeroing in a customers AR had four people from my rifle club come up to me and say where did you get that stock? Told them , for the price you can’t beat them with anyone out there. You think magpul is the star , wrong. Check these guys out , you won’t go back to any other product , bar none. Theses also come with a swivel that clips on to a bearing connection. Construction is fantastic. And the look is just awesome, puts an added touch to your work. BRAVO ZULU. Miles🇺🇸 USMC Ret.
