Can a Paracorr be used instead of a barlow? I know I'd have to make a target with a hole in the middle for the barrel end of the paracorr. I don't own a barlow and I've never used a paracorr. but I just purchased one here on AMart for my new ATM scope. I also purchased a 2" Howie Glatter Holographic Laser with the grid attachment and have no experience with one, but I hear it's pretty accurate. Anyone have any thoughts on these questions?

Yes, a Paracorr has a 1.5X magnification factor.

IMO, just get the Glatter Barlow attachment for your laser and be done with it. It screws in where the grid attachment goes and it works very well.
