Comments about Vortex Optics Vortex Optics 6.5 - 20 x 50mm Viper Series Riflescope, Matte Black Finish with Dead-Hold BDC Reticle, Side Adjustable Parallax, Tall Turrets, 30mm Tube:

I used the Weaver Tactical X-High 6 hole 30mm rings to mount it. It is very clear and bright. It was very easy to get zeroed in. I put it on a Savage Model 25 .223 caliber thumbhole light varmint rifle. I used my own loads and was able to get a group of 1" @ 200 yards. Their LRBC (long range balistic calculator) on their site is also ver helpful. I added their scope level and may get an optional custom turet they also offer. This will allow me to directly dail in the drops. I would recomend this scope and will get another for my next scope purchase.
