Standard 11.5 inch M4 Barrel configuration as used on Colt Commando Carbines, XM177E2, GAU-5.. or any "11.5 inch'ish" builds.

Some prefer the 11.5" over the 10.3"/10.5" on the MK18 due to increased dwell time and velocity. Also that extra inch reduces your "Port Pop" by almost 2,000 psi.

 

Why choose this barrel?

  • 10.5 and 11.5 are the two most Popular length for Pistol or SBR builds today
  • Nitride Finish - More barrel life and corrosion protection
  • Light Weight: 1.2 lbs

 * Note on Short Pinning:

 If all you want is a Barrel with a Front Sight Base and nothing else (Option 2) we will assume you are using a different type of Barrel Nut. We will then complete 99% of the Tapper Pin job and not pound the two Tapper Pins in tight so you can slide on your Barrel Nut. Once assembled, simply pound your two Tapper Pins in tight and you are done. We have done all the Tapper Pin work for you - you just need to do the last 1% of the job and tighten the pins down.

 

 * Note on Full Assembly:

 Everything is assembled and tightened to spec. Simply screw the barrel nut to your receiver, install your Gas Tube and you are Good-To-Go.
