I have a speed bead for a sx3/gold that I am probably going to part with. I like the sight very well, but the issue I have is the dot is in the barrel when on target so in order to hit the target, the gunbarrel has to obscure it. I believe this to be a barrel issue, not a sight/mount issue. Mine has 10 rounds shot under it and has the warbird guard, which I highly recommend. Shoot me a pm if interested.
