HAWKE do the red dot for these go for the RD30 standard rail type, just make sure you buy the one that does not say weaver in the add.
I have the weaver mount rail on my RD30 because I have the later version with the cut out for the weaver type mounts..but they do the same Red Dot RD30 that I think is model number HK3205 but check it out to make sure I am right.
Cant go wrong with the HAWKE RD30. I hit everything I aim at now...my eyes are on the way out you see, sh.t happens when you get to 48 years of age.
