Forensic g2 rifle - Thompson Center G2 Rifle Contender Composite Forend

I thought this would work on a super 16 barrel that I was converting to a rifle. I was wrong. Apparently the contender rifle barrel has different spacing than the super 16 barrel. I had to elongate the slit in the underside and add an additional screw hole. I got it to work but had to drill measure and dremmel to fix it. My fault I guess. But still works and looks good might should have been in the description about fit
