My friend just bought a used 995 and we want to mount a red dot on it. We will want to take the old site off. So I am looking for a weaver rail to take the place of the old site. Does anybody know where I can get one to fit on there that is plug and play. I am guessing this gun is older and does not have the TS stock on it.The picture shows the site that I want to remove. Thanks for any help.
