M4 Airsoft RAS Keymod Rail

cults3d

After playing a couple of games with my M4 AEG I found that the plastic handguards were just not sturdy enough for me and looked a bit too stock. I then sat down and took my M4 apart and studied the Delta ring and gas tube connection, after a while of measuring and searching Google for reference images I came up with this 10" RAS Keymod Rail. It attaches right onto the threads on the upper receiver and just screws tight, and it can be held in place with the gas tube. Alternatively you can use a rail riser or optic as I have done in the pictures to keep slight pressure on the rail as not to unscrew (it already is fairly tight). The rail is actually free floating, but I designed a mounted suppressor that screws OVER the outer barrel extension to give extra strength to the rail and keep the inner barrel secure. The suppressor has standard 14mm CCW threads. For adding rail segments I suggest my keymod rail segments (https://www.thingiverse.com/thing:2486883) design. Don't have a printer yourself?
