What is the weight difference between otherwise identical uppers, one with standard handguards and one with a QuadRail installed? I'm interested in the answer for both carbine and rifle lengths.
The catalog is kind enough to state that the tubes are 15.9 oz. and 25.4 oz., but this isn't really helpful because I don't know the weight of the stuff that gets replaced (i.e. handguards, delta ring, barrel nut, etc.)
Thanks In Advance
