Got a Remington 700 BDL Heavy Barrel Varmint. I want to add a picatinney so i can use a QD scope mount. I see there is a lot to choose from with prices at both ends of the spectrum. I dont neccassarily need 20moa built in 10-15 is probably fine. I will get a 20moa if thats what it takes to get the best mount. Thoughts? Suggestions?
