Geissele Automatics CHF Chrome Lined 5.56 AR-15 Barrel - Mid-Length - Tapered - 13.9"

The Geissele Automatics CHF Chrome Lined AR-15 Barrel is a premium barrel for the AR-15 platform, optimized for 5.56 NATO ammunition. This 13.9" cold hammer-forged barrel features a mid-length gas system and a 1:7 twist rate for consistent accuracy.

Features:

• 13.9" cold hammer-forged barrel
• Chambered in 5.56 NATO, 1:7 twist
• Chrome-lined bore
• Geissele Taper Profile
• Mid-length gas system
• .750" gas block diameter, .081" gas port
• Threaded 1/2x28
• Chromoly steel construction, manganese phosphate finish

The Geissele Taper Profile promotes efficient heat dissipation, and M4 feed ramps ensure smooth feeding under sustained fire. The chrome-lined bore and manganese phosphate exterior finish combine for corrosion and wear resistance well beyond an untreated barrel.

Founded in 2004 by Bill Geissele in Pennsylvania, Geissele Automatics built its reputation on precision AR-15 triggers -- their first, the Hi-Speed National Match trigger, was so successful the Department of Defense commissioned a select-fire version for US Special Operations. That same engineering rigor now extends across rail systems, gas systems, and complete barrels.
