About Combat Zone Stock Tube, M4
Give your M4 platform a solid upgrade with this robust metal stock tube from Combat Zone. Where standard plastic stock tubes can flex or break under load, this metal construction ensures rock-solid mounting of your stock and noticeably better durability in the field.
Robust metal construction
The stock tube is made of hard-wearing metal with a black finish that matches most M4 models. The sturdy construction minimises play between stock and tube, giving you a more precise and stable shooting position when it really matters.
6-position adjustment
The tube has the classic position stops that let you adjust your stock to up to 6 different lengths. That means you can quickly adapt your rifle to your build, or to whether you are wearing thick clothing or tactical kit.
Easy installation
This stock tube is designed for standard M4 models and comes ready to fit. It is the ideal solution if your current tube is damaged, or if you want to upgrade your rifle from plastic to metal for a more realistic weight and feel.
