F304356 : [BL-FG] DPMS Black Glacier Guards

An AP4 style handguard that utilizes 15 internal fins, rather than the standard aluminum double-shield, for heat dispersion. These unique fins, while dispersing the heat generated by rifle fire, also provide unsurpassed strength and rigidity for the handguard. Externally, the AP4 GlacierGuardsT feature 15 ribs that mirror the internal fins, and provide the shooter an enhanced grip.The AP4 GlacierGuardsT accommodate barrels with diameters less than one inch, namely the military AP4 contoured barrel and the industry standard heavy barrel. Made of a high tech, temperature resistant polymer that withstands temperatures greater than 500 degrees which allows the handguards to resist over-heating after fully-automatic fire for over 200 rounds. The fiber-reinforced polymer provides additional strength and rigidity and keeps the handguards' weight at one half pound per pair, compared to the standard .4 pounds per pair.
