Colt 10.3" Mk18 barrel, Gov't profile, special performance tuned

Colt 10.3" Mk18 barrel, Gov't profile

Specialty Tuned barrel for extreme shooters

This is the barrel for a Mk18 Mod 0 build, or for a custom short barreled rifle. 

This barrel is the 10.3" Colt Mk18 barrel.  Typical M4 (thin) profile, which is historically correct.  Factory direct from Colt. 

Standard Colt chrome-lined, to last almost forever, and that includes throwing it in the mud.  Front Sight Base (FSB) and barrel nut included.

This is a Colt factory barrel, which has been performance tuned by our friends at Specialized Armament.  They take Colt engineering seriously, and have inspected every inch of the barrel, tuned the gas port for optimal 0.70" SBR performance, check and align the FSB for perfect aiming, fit the sight base with perfectly placed taper pins, and tuned the M4 feed ramps.  This is the barrel that elite law enforcement units wait months and months for.  The performance tuning is much more than you will ever need, but good to know you have it.

Roll-marked with Colt CAGE code:  13629 M P 5.56 NATO 1/7.

Newer, correct gas port, at the correct 0.070" size.

We take special care in bringing you the best in short barrels, and use the best artisans, both in-house, and in our extended supply chain, when something has to be engineered to a Colt production barrel.  Our collectors and cloners will want the 10.3" barrel for historical accuracy.  The Daniel Defense is a great option, as it is now being used by US Special Forces in limited numbers, and is readily available and affordable.  For more authenticity, choose a Colt 10.3" barrel. 

Shooters and law enforcement typically choose the 11.5" barrel, as it has better overall performance, especially in the heavy (SOCOM) profile. Our LE customers tell us that they will only use Colt barrels in 10.3" to 14.5" lengths.  Colt truly does dominate that market, while other barrel companies own the long-range and sniper market.

As always, we are here to help.  Drop us a line, or use our online CHAT to ask about our short barrels.
