M4 AEG Buffer Tube

D|Boys stock tube for M4 AEG replicas, in mil-spec size: the buffer tube that supports the retractable stock and guides it through its positions. It is the right spare part for replacing a bent or damaged tube, or for rebuilding the rear end of a rifle during a custom build, and it comes complete with fixing screw, castle nut and end cap.

Shape and style

It has the classic M4 buffer tube profile: a black tubular body with the lower rail on which the retractable stock locks. Mil-spec is the most common size in airsoft and leaves you free to choose among retractable stocks of this standard.

Mounting

The tube is fixed to the receiver with the supplied screw and locked with the castle nut, which holds it in place and stops it from working loose in use. The end cap with screw closes the rear of the tube on front-wired replicas fitted with open-ended stocks, such as Bushmaster-type stocks. A sound, properly tightened stock tube gives a steady shoulder mount with no play, helping your aim.
