Hi guys,
Can anyone help me with dimensions for a 20 moa base for a rsa single shot action?
Thanks
George

Re: 20 moa base
How long does the base need to be? From there it is easy to calculate the height difference between the 2 end points if you are going to have it machined.

I have no idea.
Was hoping someone here could give me measurements of theirs then I could do the math.

Re: 20 moa base
GVC if you're looking at having one made Gerrie de Beer of Sudami made me one to the required inclination and holes spacing as per my receiver (all the RSA's differ as none had front holes). And it wasn't at all expensive compared to the commercial rails for other rifles.
