For my new .510 cal project I have ordered a thick PACNOR sendero barrel

I'm also about to order the NECG Masterpiece Front ramp sight and the Talley sling barrel mount ring

The problem I have is that even in the largest size both have an Inside diameter about .025 too small

I've never seen them before, so can I ask is there enough metal in these to take .025 out without making them too thin

The folks at NECG stock the most common items from Recknagel; but they will special order other sizes...just ask..
