The Echo Keymod Rail is a free float rail solution for AR owners looking for a solid platform on a budget. The barrel nut locks up with the rail via six hex bolts and timing shims used during the installation process. The Echo rail retains its slim profile from its base to the muzzle end. Oversized cutouts along the top spine of the rail body help mitigate the weight penalty, while keeping the rifle sturdy under environmental stress.
Note: The Echo Keymod Rail does not include timing shims.
