:help: What is the best way to install the M2 front sight on the M3 trunion? I was thinking about machineing it, but I don't know if there is a difference in height or what depth to go. Any suggestions of what others have done or ideas would be great.

This is actually a "early M2/M3 trunion" the block is not available from BMG parts, So this is what I did, the height might be off but I can mill it down if needed.

Looks good but I think you are going to find that the front sight is much too high.

That's kinda what I was thinking. Intel I can come up with a dimension from top of grunion to pin holes I will leave it alone ,I can always take some material off it's hard to ad it!
If anyone can give me a measurement from the top of the trunion to the pin holes that hold the sight on that would be great.
Thanks Greg

The dimension I would go by would be the two pin holes that hold the cover on for the sight. See in the BMG picture that the holes are just very slightly above the top of the trunnion and the spacer is milled to fit down in the trunnion? That would be the easiest way to get very close without and actual measurement.

That's the holes I was referring too. If I could come up with that measurement.
