The ARMS S.I.R. System (Selective Integrated Rail) is a high quality technical forend for the AR A3 flattop type carbine that combines barrel free-floating with a multitude of accessory attachment rails. In fact, the forend clamps solidly onto the flattop's upper receiver rail and provides an extended rail platform for any scope - even forward mounted scout types. Under the flip up forward rail section, there are provisions for mounting night vision devices, and side and bottom rail segments provides mount points for lasers, flashlights and forward pistol grips. The S.I.R. System includes a side sling mount, and is offered in a "no-gunsmithing" commercial (Post-Ban) model.
