This is a cut down, chopped up, highly modified M91 in a M39 Finn stock. This was already cut down before I got my hands on it. The barrel was cross drilled to make a built in muzzle break on the barrel. The scope mount bases are welded onto the rifle. A new bolt handle was added to the rear of the bolt. The bolt was lightened by 5 ounces. The barrel/receiver assembly were bead blasted for that matte finish. This rifle will shoot two inch groups with its worn barrel using handloads.
