Mil-spec 6-position collapsible carbine buttstock built on the M4 pattern — the standard adjustable stock that ships on most AR-15 carbines and the right starting point for any mil-spec build. The reinforced polymer body slides onto a standard mil-spec carbine receiver extension and locks at any of six length-of-pull positions, letting you dial the stock to your shooter, plate carrier, or shooting position without tools.
The release latch sits under the stock for easy adjustment, and the sling-loop cutout on the underside accepts a single-point or two-point sling attachment. Drainage holes and an angled toe round out a no-nonsense stock that works as a duty piece or as a placeholder while you decide on a higher-end option.
Confirm your receiver extension is mil-spec (1.148" diameter) before ordering — commercial-diameter tubes (1.168") will not retain this stock. No buffer, spring, or extension included; pair with a full buffer-tube kit if you need the complete back end.
