Product Description
The TNTE Marksman Barrels will be your go to for all your barrel needs. With the stellar accuracy from the P5R rifling you'll be the talk of all your friends at the range. Why did we choose polygonal rifling for these barrels? Rifles with polygonal rifling have smaller bore diameters than pistols with traditional rifling. This gives the polygonal barrels a tighter gas seal on the projectile. That gas seal gives polygonal guns an advantage in generating muzzle velocity. Lower chamber pressures than conventional land/grove rifling, lending credence to their claim of less deformation force.
