I just bought a new Nightforce 20MOA rail for my Bergara Premier HMR Pro 300WM (Long Action).
I checked on ways to see if it needs to be bedded, and if I snug down the forward most bolt, there's 0.31mm of clearance at the rear of the rail/receiver. You can see it kind of "spring board" when I press down on it. But 0.31mm is like 3 sheets of printer paper.
If I snug down the rearmost bolt, the front is snug. I can't fit anything under it.
I was curious if the rail is bent, so I placed the rail upside down on a very flat/true surface and sure enough the top of the Picatinny rail does not sit flat. There's clearance/light going through the center top of the rails. In other words, if you look at it right side up (the rails facing the sky) it'd be like the bottom of a "U" (exaggeration) towards the center.
To me, if I bolt down the front of the rail the rear is obviously going to sit high because the rail isn't flat. If I were to bed it this way, wouldn't it just be compensating for an untrue rail? And if I were to just send it and torque down all 4 screws, it might flatten it out?
Has anyone checked to see if their rails were flat/true before bedding?
