I have some Ruger rings for the mod 77..what size are the scope rings screws in Ruger rings???

Thats strange, nobody in the gunsmithing forum knows what size thread a Ruger ring has, I thought 6/48s not so, maybe 6/40s

Need help guys.

6-40

I've been buying the 8 packs of the t-10 head to replace the original flatblade screw heads on all of my m77's. Amazon or direct from Ruger was best

Thats my plan, they just last better and look better...Thanks

Ruger no longer sells those 8 packs, nobody does!

I did find a sourse that sells 6/40x1/4"...I don't recall who had them as it was on E-Bay..I will let you know when they get here, Im sure they will have a return address on the package..
