Hello

can I buy only rings for k31 without rail? Rings material is steel or
aluminum? and upside rail is 12mm?

thanks for info

by Petr

Dear Sir!

The material of these rings is steel.

We believe that the dovetail is 12mm indeed.

by Optics Trade team

Does the price include the base plate and dovetail which mounts onto the rifle?
I already have a 25mm scope but want to change to 30mm, so what do you offer?
Many thanks
Kind regards
Charlie

by Charles

Dear Sir!

This is the whole mount. The base with dovetail that is mounted on the side of the rifle, and then the 30mm rings that are attached to the dovetail. If you already have one such Rusan mount with 25.4mm rings, then we can offer you 30mm rings only. A gunsmith can then reassemble the scope mount so that it will feature 30mm rings.

Hello. I would like to know if it is possible to order only the two offset collars (in 30) for the k31, because I already have 2 rails, one in steel and the other in aluminum. Thank you in advance for your response.

Bonjour. J'aimerai savoir s'il est possible de commander seulement les deux colliers déportés (en 30) pour le k31, car j'ai déjà 2 rails , un en acier et l'autre en alu. Merci à l'avance pour votre réponse.

Hello, What is the optical axis height regarding to the bore height with this mount ? It would help me choose the right scope. In addition, I suppose this mount allows the scope to sit vertically above the bore axis, not offset, am I correct ? Best regards, Antoine
