The Colt 14.5" M4A1 SOCOM barrel is the heart of any authentic M4A1 Block II clone. This is a genuine Colt factory-manufactured barrel featuring the SOCOM-profile contour, chrome-lined bore and chamber, 1:7 twist, and the correct F-marked front sight base with bayonet lug and side sling swivel — exactly as fielded by US SOCOM units.
Critically, the barrel ships factory pin-and-welded with the CAGE-coded manufacturer markings intact, delivering a 16"+ overall length that keeps the assembly Title I legal while preserving the 14.5" barrel profile seen on issued M4A1 Block II rifles. The pin-weld is done at Colt's facility to government specification, with a proper flash hider permanently attached.
The SOCOM profile — heavier under the handguard, stepped down at the gas block — is the signature of the Block II upgrade program and cannot be replicated by commercial government-profile barrels. This is the correct part, period.
Use it to build a CAG, DEVGRU, or Ranger-pattern M4A1 clone that will stand up to the most exacting scrutiny. Compatible with Geissele SMR rails, Daniel Defense RIS II, and Knight's Armament URX systems. Order yours today — Colt SOCOM barrels move fast and rarely come back in stock.
