Available at Evike.com is the EMG 8-Position Ultimate M4 Buffer Tube with version for the Ares Spec, Real Spec, and Marui Spec. Matt gives as a quick look in this video... "The enthusiasts here at EMG go back and forth with various parts trying to find what we like best in our builds. However, every now and then when we cannot find something that matches what we are looking for, we have it made ourselves; thus the EMG Enhanced Buffer Tube was conceived.

The EMG Enhanced Buffer Tube features enhancements to improve overall usability, reduce weight, and improve durability. Also let's be real chief, half of the stuff we buy for our guns we do so to make them look cool so we definitely didn't want to gloss over that aspect. To achieve all this, we consulted a manufacturer of real AR15 accessories to help move this project forward. What we have come up with was a Mil-Spec buffer tube made from 7075 Aircraft Grade Aluminum that we have facets milled out to shave off excess and unneeded friction and weight. We spaced out each adjustment notch to be closer together with eight total positions which allows for much finer adjustments for your preferred length of pull.

Additionally we have the buffer tube drilled and tapped so a stop-screw can be installed at your preferred maximum length of pull so under gross motor skill scenarios, the stock can be easily extended to your preferred length each and every time. The buffer tube is available for Tokyo Marui spec, G&P / ARES spec, as well as real spec (gas blowback) lower receivers; each buffer tube is hard anodized for weather resistance and comes in various colors to fit not only your tactical builds but also your hot rod, race/competition builds as well."
