I have been looking into either the Manners T5A or the T5 for my .260 build. My question is, do I need the adjustable cheek or not? I am running a USO SN3 with a 44mm objective, I am thinking that I should be able to run low rings, or possibly extra low rings with this setup. The barrel contour is a rem varmint. The advantage that I see with the non adjustable cheek is the weight savings 2.7lbs vs 4lbs. What do you guys think? T5A or T5... or something else altogether.
