ihookem, Benchman is dead on with the peep sight thing. Hands down will improve groups, but I would try it first prior to taking it off for hunting. Most guys I know just remove the screw in aperature and leave the rest as a ghost ring if they don't care for the aperature while hunting. POA won't change, and it is pretty fast to acquire the sights.And just a note if you're interested, I get my pillow ticking from Track of the Wolf, precut and Wonder Lubed.
Please let us know how that barrel works out.
