| Yes, paint is a big issue.
Since you are using an open-bolt marker, I'd suggest that the barrel be overbored a bit. Something around .689 is what most open-bolts are equipped with these days. If people start going off about paint to barrel matches, take their advice with a grain of salt. With a tight bore barrel, the problem of bad paint is compounded.
Take things one at a time. If you aren't happy with a barrel, go on to a regulator, and so on. If you slap everything on at once, you won't know what finally helped. |
