Sons of Liberty Gun Works P3 Fighting Chrome Lined 5.56 AR-15 Barrel - Intermediate - Medium - 16"

The standard-length AR-15 fighting barrel, built to SOLGW standards. The Sons of Liberty Gun Works P3 Fighting Barrel at 16 inches delivers 5.56 NATO in a full-length carbine platform with 41V50 chrome moly construction, a chrome-lined bore, and intermediate-length gas -- a configuration that maximizes velocity, cycling reliability, and bore longevity in a patrol-weight profile.

Features:

• 16" barrel, Medium contour
• Chambered in 5.56 NATO
• 41V50 chrome moly steel
• Chrome-lined bore, black oxide exterior finish
• Intermediate-length gas system
• Threaded 5/8x24
• .750" gas block journal
• 1:7 twist

41V50 chrome moly steel provides the structural integrity and heat resistance required for sustained 5.56 NATO fire, and chrome lining extends bore life and corrosion resistance significantly over a bare steel bore, simplifying maintenance after high round count sessions. The intermediate-length gas system operates at a lower cyclic pressure than a carbine gas system on the same barrel length, delivering softer bolt carrier velocity, reduced felt recoil, and less bolt carrier group wear over time.

Ideal for patrol rifles, duty AR-15 configurations, and standard-length builds where a chrome-lined 5.56 NATO barrel with intermediate gas delivers the best balance of reliability, velocity, and service life.
