Geissele Automatics Geissele Super Duty 5.56 NATO 14.5″ 1:7″ CHF Bbl DDC Stripped Upper Receiver w/13.5″ M-LOK MK16 SMR 08-246S

Geissele Super Duty 5.56 NATO 14.5″ 1:7″ CHF Bbl DDC Stripped Upper Receiver w/13.5″ M-LOK MK16 SMR 08-246S is an ideal addition to any custom AR build, bringing the quality and craftsmanship Geissele products are known for. The Geissele 14.5 upper pairs a 14.5″ cold hammer forged, chrome-lined barrel with a 13.5″ MK16 Super Modular Rail, seamlessly attached via center-aligning tab to eliminate any chance of rail rotation. That’s a real point of failure on lesser rails – a loose handguard walks a mounted optic or light off zero over time, and this mounting system is built specifically to prevent that. Manganese phosphate coating adds another layer of durability on top of the chrome lining, extending service life across high round counts. As a Geissele Stripped upper, it comes without charging handle, BCG, or muzzle device, giving builders full control over which internals go into the rifle. Key Features: 14.5″ cold hammer forged, chrome-lined barrel, 1:7 twist Manganese phosphate coating 13.5″ MK16 Super Modular Rail, center-aligning tab mount Stripped configuration – no BCG, charging handle, or muzzle device Desert Dirt Color finish 5.56 NATO chambering Fits any mil-spec AR-15 lower receiver Rail rotation-resistant mounting system This Geissele Super Duty upper 14.5 hands builders the hardest part of an upper build – a properly manufactured barrel and rail – while leaving the rest of the parts selection entirely up to them.
