Has anyone F1'd their ACR yet and/or undergone an SBR bbl change?
I realize there arent any short ACR bbls out yet (and probably wont be for awhile). But after seeing the thread about retrofitting a Daniel Defense CHF bbl, I was wondering if anyone has tried the 10.3" or 14.5" bbls or even a 10.5" bbl from another manufacturer.
Barrel work is quite easy, s.s. 10.5" custom contour, only issue was the piston length. Was easy to replicate on the lathe, heat treated, coated, and ready to go. Will post pics once the F-1 comes back.
Haven't worried about the barrel length yet. I filled out the form for a 10.5 barrel. The gas port is the issue, as I was told my smith can cut ,balence and weld the piston to propper length. Might have to order a custom and go from their
