Buffer Tube Delta Armory AEG M4 — Black

Metal alloy buffer tube for M4, M16 and AR15 platform AEG airsoft guns. With a length of 187 mm and a weight of 88 g, it is the structural component that connects the rear receiver to the adjustable stock, houses the spring assembly and defines the shooting geometry.

The fully metal alloy construction eliminates the play and flex typical of polymer tubes, transmitting the recoil spring response more directly. This results in a smoother firing cycle and reduced wear on the internal components that work in contact with the tube. The trade-off to consider is between rigidity and weight: compared to a polymer buffer tube, the 88 g of the metal tube has a slight effect on the overall balance of the airsoft gun — a relevant factor for those choosing lightweight configurations for dynamic shooting.

The package includes the internal fixing screw with washer and the external locking nut (castle nut), allowing complete installation without the need for additional parts. The 6 adjustment positions let you adapt the stock length to your build and gear, maintaining the same operational flexibility as reference systems on the AR platform.
