While the M16 and M4 platforms are synonymous with Colt, FN has been supplying our armed forces with the rifle for years. FN is proud to announce the release of authentic M16 and M4 complete upper receivers and stripped lower receivers under their FN 15 Military Collector line. Now hardcore AR aficionados can build a rifle as true to the original model as possible, minus the fun switch of course.
FN is now offering stripped lower receivers to outfit your own M4 or M16 replicas. [FN USA]The FN M4 and M16 lower receiver is manufactured at FN USA’s facility in Columbia, South Carolina. These receivers are made of forged 7075-T6 aluminum and have a black anodized finish. The lower is made to Mil-Spec standards and even includes the auto designation on the selector switch. Although it is made to reflect the standards set out by the Department of Defense, the inside of the receiver where the fire control group is inserted is machined to prevent select-fire operation.
M4 and M16 uppers are now available to complete a near-facsimile to the DOD-approved rifle. [FN USA]If you already have a suitable lower or are looking at the new FN lower, consider the complete M4 or M16 upper from FN. Both uppers come complete with a government-profile barrel with a 1:7 twist and a Knights’ Armament upper handguard with rail covers. Both also wear a folding MaTech rear sight and an A2 post front as well as foregrip and bayonet lug to complete that War on Terror impression. The M4’s barrel is chrome-lined and is 14.5 inches long with an A2 muzzle brake that meets the 16-inch minimum legal length. The M16 comes with the same features as the M4, save for its rifle-length gas tube and its 20-inch barrel. The MSRP for the M4 or M16 lower receivers is $154, while both uppers come at a price tag of $1,682.
