All configuration are currently in stock (For now..)

Standard 10.5 inch M4 profile barrel as used on a variety of "10"ish" builds (10", 10.3", 10.5").. for example XM177, Commandos, Mk18, C8, etc.
Note on Mk18: Though the 10.3" length is most famous, many Mk18's have also been fielded with 10.5 inch barrels (LMT, Colt). It is a myth only 10.3" barrels are correct for the Mk18. In fact, there is no "official" configuration for the Mk18.
Why choose this barrel?
- 10.5 and 11.5 are the two most popular lengths for Pistol or SBR builds
- Standard length currently used by SOCOM
- Available in 1:7 or 1:9 twist rate
- Light Weight: 1.1 lbs
- Nitride (Melonite) coating - increased Barrel life and corrosion protection
- 10.5" is the shortest most folks can go and still install a suppressor

* 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.
