Looking good!!

I recognize the .50cal parts as I am doing the same with the .50cal on my M51.

The damn rear sights though. The rear sight housing isn't a problem, but the actual site that goes in it.

I had 2 of the RB dress up kits and both rear sights went flying. Couldn't find them...so of course, I cobbled together a reasonable facsimile to replace it. Get it done, couple of hours later I find one of the rear sights sitting right in the open, in plain view under my nose.

Sometimes I really hate Murphy!!
