Geissele GDP MOD1 Highwayman 5.56 NATO 10.3-inch Pistol, Black The Geissele GDP MOD1 Highwayman combines a 10.3-inch 5.56 NATO barrel with a GDP pistol brace and a black finish. The cold hammer forged, chrome-lined barrel uses a tapered profile and a 1:7 twist. Those construction details accompany a compact pistol configuration with a HUXWRX flash hider, giving the Highwayman a clearly defined barrel, brace and muzzle-device combination. A fully ambidextrous lower receiver places controls on both sides, accommodating left- and right-handed handling preferences. The SSA X trigger, MK16 handguard and Airborne Charging Handle are part of the factory configuration. The telescoping GDP brace has two locking positions, while the A17 grip provides a reduced-angle gripping surface. A magazine is not included, so the pistol should be selected with that package limitation in mind.
