Best bore sight, reticle alignment tool?

[whenindoubtfixit]

I'm looking for some advice on a multi-caliber bore sighter / reticle alignment tool. Preferably carried by a CGN dealer. First candidate is Rem 700 with 50mm objective with high Warne mounts. Thanks for your help with this.

Save your money, use a plumb line to level your recticle and bore sight it by looking down the bore.
