Golden Eagle M4/M16 Retractable Crane Stock, Black

Upgrading your M4's stock is about more than looks. A crane stock gives you real adjustability and actual battery space inside the buffer tube, which is the problem most players hit when they try to run a proper LiPO or a longer NiMH pack. The Golden Eagle Crane Stock is built for that job.

What the crane design gives you. Unlike a fixed A2 stock, the crane tube extends and collapses to multiple positions, letting you dial in length for body armor, winter gear, or just your own fit. More importantly, the hollow tube is sized for nunchuck-style batteries, so you can route a 7.4V or 9.6V pack through the stock and into the receiver without stuffing a battery in the grip or buying a separate battery compartment.

Externals. The butt plate is rubberized and ergonomic, which makes a noticeable difference during long skirmish days. A metal rear sling mount replaces the flimsy plastic loop that comes on most stock M4 buffers, giving you a solid anchor point for single-point or two-point slings. The finish is black, matching standard M4/M16 externals.

What's not included. This is a stock only — it does not come with the M4-type buffer tube itself. You'll need to install it into an existing buffer tube or source one separately. If your current setup uses a fixed A2 or a PDW stock, verify your buffer tube is M4-threaded before purchasing.

Compatible with M4 and M16 AEG platforms that accept standard crane-style stocks.
