I bought my son a axis in 308 hb. 1st question is there any other aftermarket stock options besides MDT chassis,and boyds? 2nd question I'm looking for a 20 moa base picatinny style not the weaver multi slot style. I've seen some but some pictures of them are like the weaver multi slot but say picatinny. Does anyone run a 20 moa true picatinny base and what brand? Thanks!
