Our take: This is a lightweight aluminum replacement airsoft Buffer Tube for M4 CQB / crane-stock equipped AEGs. The M4 CQB crane stock Aluminum Buffer Tube can be attached to most M4 CQB series AEGs and/or carbine AEG rifles equipped w/ standard crane stock(s) including JG, CYMA, DBoys, A&K, AGM, Echo1, Tokyo Marui. The Buffer Tube is constructed entirely of High grade and lightweight Aluminum, and is extremely durable. The Buffer Tube has six different retractable stock positions, perfect for any style of shooting. This Buffer Tube's locking ring is fully adjustable and detachable, providing a secure fit on any AEG. The JG Lightweight Aluminum Replacement Buffer Tube is CNC machined, and is super lightweight weighing only 7oz.! The JG Factory replacement M4/ M16 Buffer Tube DOES NOT come with the mounting hardware necessary to mount it to an AEG.
