**COMPATIBLE WITH M4 AND PRIOR MODELS**
The Backbone Rail from AirMarksman is more than just an extended optics rail. This accessory has been designed to tie your entire rifle together and eliminate tolerance stacking by replacing both the factory optics rail as well as the factory backbone plate with one piece of extra rigid aircraft-grade aluminum. It reduces flex in the entire rifle, creating a more anchored and consistent shooting platform at the cost of only 4 added ounces to the total weight of the rifle.
On top of stiffening the M4 platform, the Backbone features a full 14 inches of Picatinny optics rail, the most useable rail space of any rail system on the market, with 30 MOA of elevation milled into the rail. Based on input from top NRL Airgun Class shooters, AirMarksman also added a bolt retention detent to this rail that keeps the cocking handle and bolt probe held in the rear position when it's opened. This feature prevents accidental double feeds and removes play in the cocking handle. The bolt retention detent can easily be removed during the installation process if shooters are looking to maintain the factory cocking handle feel.
100% made in the USA, the AirMarksman Backbone Rail System is the ultimate precision top rail for the M4 platform.
