The Tapered, Heavy, Improved 13.95" barrel is our first barrel, made to our own exacting specifications.
The Tapered profile moved the balance point to the rear (versus traditional profiles) reducing the "front heavy" feeling that most barrels feel like once commonly used accessories are added to your firearm (lights, suppressors, etc). By added material towards the rear, the THI barrels are stiffer than normal, and better at managing the increased heat generated by high volume suppressed use. This added stiffness reduces the shift in zero between suppressed and non-suppressed use versus lighter weight profiles, as well.
As this profile is heavier than normal, with a nominal weight of 1lb 14oz, it's also MARYLAND LEGAL, and is H marked right on the barrel to comply with MD state regulations.
An improved part of this profile includes an extended .750" diameter gas journal, dimpled for secure low profile gas block installation, but also long enough for a traditional FSB to be installed.
Each barrel is individually inspected by us here, as well as by our OEM at multiple points during the manufacturing process. This barrel will exceed 16" in length with any of the following muzzle devices once pinned and welded:
SOLGW
NOX, NOX-9, NOX Two Chamber Brake, NOX no-mount
Surefire Warcomp Flash Hider (open tine)
Dead Air Flash Hider
