The best 20 moa base you should buy first - NightForce XTRM Base

This is the 2nd 20 MOA base I purchased. The first was from a competing website and a different manufacturer. Although it fit the rifle, it was mislabeled as a 20 MOA, did not give any additional adjustment, and was an overall disappointment. This piece in contrast, was clearly to notch upon opening the package. The Machining is incredible. The difference between the two was obvious. This piece was around 60% more expensive but it was worth every penny of what I paid for it plus the failed base it replaced. If this is a true precision application, do not try the cheaper bases first, buy the nightforce.
