I wouldn't think normal paper would block out enough light but thanks. I could easily get my hands on some binder/file covers, I wonder if blue plastic would have a better effect then transparent. Thanks for the tip, your rifle is pretty damn awesome, shame about the Victorian Police it seems they just love busting you guys balls.The counter is just word art on normal printing paper, the plastic your average thin acetate used in binders etc, just simple stuff I had lying around!
