If you've bashed your buffer tube and it's looking a bit tired, this will assist! The Specna Arms Polymer Buffer Tube for M4/AR-15 CORE™ AEGs is a replacement original part made from high-density polymer. While it is designed for Specna Arms CORE M4/AR-15 AEGs, it features standard AEG buffer tube lugs, so it should fit almost every M4/AR-15 or AR-9 platform out there.
The buffer tube, aka receiver extension or stock tube, allows you to mount and adjust an M4/AR-15 sliding stock to 6 positions. It also serves as the battery compartment in rear wired M4 AEGs. Being made from polymer, this buffer only weighs 85g approximately, making it a great way to save weight on a speedy custom build!
