New centurion rail for the 6920. Thanks, @Notso, for the aimpoint, and @dontshakepandas for the light

The barrel came with a standard FSP. I used my porta-band saw and a Dremel tool with sanding and grinding bits to chop it and reprofile it. It took a lot of trial and error and fitting to get it to work with the extremely narrow Centurion rail. Best method I came up with was dry fitting the rail and marking the areas that rubbed against the rail with marker and then ground it further.
After getting it to fit properly, I painted the gas block with two coats of black high heat barbecue grill paint. Has worked well so far.
Well played - again, the rifle looks great.
I'm a big fan of the Centurion Arms CMR series and have been considering a similar project.
My primary concerns are/were: potential clearance issues with the Socom barrel and cut down FSP inside the rail.
Thanks for the info - if you have any photos of the FSP chop & grind process/results, would enjoy seeing those as well.

No pictures from the build unfortunately. One thing with the Centurion rail is that when you use it with a SOCOM barrel, the meatyness of the barrel walls make the machined in QD sockets unusable on the rear of the rail. I had to buy a Magpul QD mount and place it on the rail just forward of the rear socket. Works great, but it's another ~$25 added on to the build cost. Price you pay to be different.
