With scope, the Omega weigh 8.37 pound.
With scope, the Knight weigh 8.72 pound.
The Knight has a 3-9 ultra-light which is supposed to weigh 8.8 ounces. The Omega has the 2-7 power VX-2 which is supposed to weigh 9.9 ounces. I weighed neither scope. The rifles have the same rings. The Knight has a 2 piece base; the Omega has a 1 piece base.
The Knight have a barrel that taper nicely and looks sleek. The Omega have a 50 caliber barrel that has a 45 caliber hole drilled in it, and looks kinda like a target rifle barrel, or a varmint rifle barrel, kinda like what is called a bull barrel, but not so much.
Much more steel around the barrel hole of the Omega, compared to the Knight.
Compared to a 50 caliber Omega, the 45 caliber Omega is 1/4 pound heavier, no doubt due to more steel in the barrel.
