Looking for information on installing a modern scope ring on the old style target R/F scope blocks. I would like to protect my Redfield 3200 w/ something like a Burris Signature ring, just not sure on fit. The Rimfire Standard blocks on my H&R M12 appear to be a odd dimension, a 3/8" mount is very loose when slid into place. Any ideas or suggestions?

thanks, BRKHornet

Thanks for the quick reply. I tried a set of Talleys for a CZ American which are suppose to be 3/8" and they will not tighten up. I  slid a BKL mount on and it was also loose. I'll check out the Kimbers. Are the Unertl bases the Posa style?

Thanks,

I used rings for the old type Kimber bases, which are dimensionally like the Unertl, with the exception of a recoil shoulder on the front side.  The newer Warne Premier rings (now out of production, too) used a groove across the base and a lug inside one of the ring bottom sections to stop recoil movement.  Talley rings still are intended for the shoulder.  Rings that are gun specific will probably not work on Unertl bases.

Thanks for the tip on Millet Rings, I'll keep this in mind. In regards to the value of the 3200 scope, what I'd really like to do is install Burris Signature R/F rings on the rifles's Std. target blocks. I'm just not sure without ordering a pair if they will fit snugly enough. I guess if they would not clamp up, I could have a machinist make correctly sized target block replacements.

Looks like a solid set-up. Does it shoot well? I also have a BKL mount w/ adapter to mount modern scopes for the M12 although what I'm trying to do is a bit different. The M12 came with barrel blocks and I intend to install a period correct Redfield 3200 24X to these blocks. I have the original Redfield mounts although don't feel the quality is there and want to use a modern mount such as a Burris Signature w/ inserts to protect my investment on the scope. The issue is the rings have to fit the blocks and this is where I see variables. I may just spring for the Burris rings and have blocks made to fit perfectly if the originals do not.

My Standard Target blocks do measure 7.2" between centers. Can you explain your adapter in detail and which rings will fit? Will a Burris Signature Rimfire ring fit?

Thanks,

Thanks for posting the picture. Looks like a neat way to do things. I've been sorting through some ideas I have and may have discovered a method to allow me to mount the scope. I have to get some more dimensions and order couple parts.

Thanks,
