This 10.5 inch barrel can be used for a variety of 10"ish builds (10", 10.3", 10.5").. for example XM177, Commandos, Mk18, C8, etc.

Unlined means this barrel's individual strengths are accuracy and affordability. Same phosphate finish used on US military barrels.

Note on Mk18: Though the 10.3" length is more common, many 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?

  • Lowest cost choice, without compromising quality.
  • Unlined is both authentic to short barrel builds before 1969, and all things being equal offers the maximum accuracy potential (without going to stainless).
  • Unless you are planning to shave the Bayonet lug (or use a low pro gas block), 10.5" is the shortest you can go and still install most direct thread suppressors.
  • Your SBR form already details a 10.5 barrel length.
