The 901552 is a 22” long, 22 Rim fire barrel for the 77-22 receiver. The Blued octagon profile is tapered from .920” at the receiver end to .675” (dia) at 4.25” straight to the muzzle. The precision reamed Bentz chamber and 1:16 right hand twist Green Mountain Rifling finish the bore.

The 22" barrel makes the rifle "feel" better to me. The finish and bluing is nice, looks good on the rifle, and it shoots very well. I already have a 17HMR barrel on another 77/22, very pleased with it also. I have some Green Mountain muzzle loading barrels, satisfied with them too.
