Re: POF 308 HSR Rail
I am shooting a POF308 16.5 with HSR rail using Badger High Max Alloy rings with a Vortex 2.5-10X44 PST. The rings are listed at 1.125. I think there is enough room for a 50 mm bell but can not be sure for your use. Proper cheek weld and eye relief would also depend upon your stock. I am using a Magpul UBR with my set up on the POF. I have a GAP-10 set up with a F1 and a PRS. I am using a little bit of up adjustment on the cheek piece and have a similar level of cheek weld between the two rifles. The PRS is better for adjustments. I hope that helps a little...
