Can the use of o rings to orient the broadhead affect an arrows accuracy negatively?

I would say yes, if they were not designed to use them.

I've read alot about guys using them for tuning bheads, but have never tried it. I would think if they helped get orther wise un controlable wobble out, they might help. I'm not much for stuff that ain't tight and right and have found my set up for something less than millions of dollars, lol. Test em out and let us know???

My Bruin Lite's use rubber o rings. They tune up fine. Don't shoot any groups 30 yds. and closer with mine or ruin B'Heads quick.[]
