Collector Value:
A.R.M.S. permanently halted production on these early-2000s S.I.R. weapon systems. Finding individual components—especially brand new in the original factory wrapper—is nearly impossible. This is a goldmine part for a serious clone builder or collector who needs a flawless top rail to finish a build.
