Evening gents have a question from a newb. Recenty purchased the 700 as my entry level platform to start working my way out to distance. I bought the 700 sps in 308 with the 20inch heavy contour barrel. Picked a nikon m-308 4-16x42 bdc that fit into my budget along with the leupold mk4 30mm med rings. Question I have is I know that the 308 takes the SA base but a friend gave me a LA leupold mk4 base and I would love to use it seeing as it would save me 100$ is this possible or should I start the bartering process now while im awaiting the DROS period here in the lovely republic of California. Thanks in advance any other input would be greatly appreciated seeing as this is my first step in the bolt action world.
