That is what we are looking at right now. $670 for an R-1S and $625 for an unknown. The extra $50 could put him in a Springer.
I have seen the spherical bushings. You seem to like them. Worth the effort???
I do like them, but only if the pistol has a bit of barrel binding happening. The Remington barrel bushing to barrel fit was very good, but just before the slide would return to battery, the bushing would bind a bit and the barrel would be pulled forward and try to engage the upper lugs before they were lined up. Just about every Remington I've looked at has that slight catch just before the barrel returns to battery and the angled bore bushing eliminates it. I'm sure that shooting would eventually eliminate it too.
