Have M21 receiver sight on my 1895

Need taller than standard FRONT sight blade.

Since new eyeglasses are thicker, end up looking through the edge and seeing a double post when I lower head to sight.

Need to raise front sight as the receiver sight is near lowest setting with standard blade.

That way I can raise rear receiver sight and won’t have to lower my head on the stock as much and won’t then have to look through the eyeglass lens.

It’s better for shooting to see only one post…..LOL

Does anyone know where I can get a taller than standard front sight blade???

thanks
