The A.R.M.S.® Selective Integrated Rail System includes more unique and helpful features for the professional user than all other devices combined. Only the A.R.M.S. ® S.I.R. ® System allows you to have dovetail rails where you want them and not where someone else has decided for you. This modular receiver sleeving system is a hand guard universal mounting system that leaves the barrel totally free-floating while providing a rigid ultra-light platform on which to mount virtually any mission specific accessory.

Features:

• Free floating barrel design to achieve maximum accuracy potential.
• Removable side and bottom dovetail rail panels for mounting accessories such as lights, lasers and vertical forward grips.
• Drastically enhanced cooling.
• Lightweight and rugged aluminum construction.
• Quick Change Lower Handguard.
• Available in both Civilian(C) and Military(M) configurations. (Installation of Military S.I.R. ® Variants requires removal of the Delta Ring/Handguard Retaining Ring).
• The S.I.R. ® System is designed to fit mil-spec flat top receivers from Colt, Armalite, STAG, Rock River Arms, Barrett, CMT and Bushmaster in the 5.56 or 6.8 cal carbine, mid, and rifle lengths. The #51 S.I.R. ® Allows mounting to the carbine A1/A2 carry-handle. There may be other flat top receivers manufactured that the S.I.R. ® may fit to properly, but we do not guarantee or warranty the S.I.R. ® on any flat top receivers other than those listed above.
