BP1415 Green Mountain Rifle Barrel 15/16" X .50 Caliber X 36" Length

Machined from finest quality American round bar stock, pre-straightened before drilling to assure minimum run out. After drilling, all barrels are reamed three times then burnished for highest quality bore finish. Rifled with 8 lands and 8 grooves with a nominal groove depth of .012. After rifling, the barrels are mounted between centers and milled octagon, assuring a bore true with the flats, then polished to a satin finish. Requires small amount of polishing of the flats before final finishing. 5/8X18" thread and a 1 in 70"twist.
