I have a Remington 700 with a heavy varmint contour barrel and I am installing a Vortex 6.5-20x44 and have a EGW 20 MOA base and was wondering what height rings that I would need.
Any help would be appreciated. |
| Hard to tell. The heights do vary from mfr to mfr. You DO want it as close to the barrel as possible, so start low and work up. The 44 objective lens is not huge, so I would try shorts first, then medium, but I do have them all in my toolbox. I want the objective lens about the thickness of a dollar bill from the barrel. |

the other question is should i go with a 20 moa base or o moa. I will be mainly shooting from 100-400 yards but may at times shoot to 1000. I dont want the 20 moa if i wont be able to zero at 100
with the vortex viper i think it has 65 moa of adjustment which might get me close to 1000 with the 0 moa but i dont know. it is a 308 |

The 20 MOA base will work fine. It will give you a theoretical 12.5 MOA of travel to sight in with.
Low rings will work, mediums if you're really worried. Don't sweat ring height too much as it's not critical like the Internet says it is. As long as you can mount it and get a comfortable head position, you can account for ring height over bore with a ballistic solver. |

1. Mount your base to the rifle.
2. Stack washers (or pennies, nickels, quarters, etc) in even stacks on the mount about where your rings would go. Build the stacks up until you get the scope at the ideal height that you want. 3. Take one of the washer stacks and measure the height (preferrably with calipers). You will now have your ideal saddle height (top of the base to the bottom of the scope body or tube). If you don't have calipers, then use pennies for your stacks. The average penny is .0593". I made myself a chart with the heights of all the various decent quality rings. I also keep quite a few things in my shop. Let me know what height your stacks are and I can look at my chart and save you some research. |

You will not need higher than 1.00", especially with a 44mm objective. Do you know the outer diameter of the objective?
.87-.885 should be perfect with the possibility you can go lower based on the outer diameter. I suggest use the best rings that you can afford as your mounting solution is the most critical junction between your weapon and riflescope. |
