please recommend a good laser boresighter compatible with a 12 gauge. thanks.
I just purchased a Firefield laser boresight from Optics Planet for $25, it looks like a 12 gauge shell. Used it to bore sight the FFII I added. Started at 20 yds, and it was only off a hair. Made a slight adjustment on the FFII, and she was dead nuts at 40 yds in about 3-4 shots!!
