New MVA sight rocks

Post by MSalyards » Tue Aug 02, 2022 11:05 pm

So I purshased a new sight from MVA and when I installed it I broke one of the screw heads unknowingly. When I found it and was able to remove the rest of the screw, I sat the sight on the rifle and it rocks. If I were to screw down the front screw, there is a air gap between the back of the sight and the rifle maybe a business card thick. Not normal right?

Not normal , I have had one screw break and MVA sent two. I was told by MVA that the heat treatment sometimes makes the screws brittle. Certainly not laying flat against the receiver is a problem,if you can snap some pictures showing the problem send them to MVA. Bet they can diagnose either the sight or the rifle is the problem.
You didn’t mention what rifle or sight,so I’m assuming a Shiloh and have doubts that it’s the rifle, has a tang sight been mounted on the rifle before ?

If it's a model 77 when you tighten the sight screws it puts the proper tension on the sight spring. The spring extends down a bit when not mounted. the sight will rock somewhat before the screws are tight. When mounted and tightened the spring bends to the correct place to keep the sight vertical. I know it sounds odd but it works.

Its a recent #3 sporter and It is the sight. They did send me screws and the spring is not touching . #130, it fits up in the sight frame. It has a tiny rock when set on a piece of glass.

Why don't you call MVA and ask the sights maker?

They don.t seem to answer the damn phone, I have also emailed them and did recieve 2 screws but no answer on the sight base. I was gonna try to flaten it myself but I decieded to just slide a shim under one end to take up the space.

Either shim or stone the base, tang and receiver tops are seldom a perfect uniform surface curve after the polishing.

Coat the base of the sight with lipstick. Put in place and move it slightly and you’ll see if you have high spots on the tang of the rifle.

Most likely the radius on the bottom of the base is not quite parallel with the base. You could take your sight to your local hardware and find something round that’s close to the size. With some wet or dry sandpaper you might be able to smooth it out so that it doesn’t rock or at least not as bad.
