Noveske Leonidas CHF Chrome Lined 5.56 NATO FSB Barrel - 12.5" (for a short barrel rifle or pistol; it is potentially a component of an NFA item, buyers should abide by all relevant laws and restrictions). 


Noveske chrome-lined barrels are made using the cold hammer forged barrel manufacturing process. These methods harden the steel around a rifled mandrel, which creates the lands and grooves. The bbl is then chrome lined to the same spec as an M249 SAW (which is about twice as thick as that of an M4 barrel). The result is a gun bbl that can be run hard, day after day. For high ammo counts, high temperatures, and other aspects of heavy shooting, they recommend the Noveske CHF bbl.

Legal Notices

A 12.5" bbl used in AR 15 rifles could make the weapon an SBR, assuming it is not a pistol; we don't assume that because it seems like there are different laws each week. Perform your due diligence before utilizing a Noveske Leonidas 12.5 barrel or any short barrel. It'll save you some hassle and possibly a trip to the local ATF field office.
