Who makes bases for a Heym SR20??

I have Redfield bases on my Mauser 3000 and I think it is the same rifle as your Heym....the 3000 was made by Heym anyway. I also think the Volquartson rifle sold a few years back was the same gun.

Contact New England Custom Guns ( www.newenglandcustomgun.com ) ). Also, note that Heym has a web site, and would probably be able to provide you with a mount!

Leopold make bases that fit the SR20. I have had a couple of sets over the years on my SR20s.

Use the bases you would normally buy for a Mauser 98 - I think! Either than or the Mauser FN.
