I recently sent my M83 475 Linebaugh in for a couple of modifications. I wanted a round butt and an action job with a 3 pound trigger. I sent the gun in on a Wednesday via UPS next day. I called on Tuesday, a few days later and ordered a few green fiber optic sight blades for both the M83 and my M97. I asked them to mail the sight blades priority mail assuming I would be able to mount the blade on my M97 45 Colt and play around while I waited for the return of my M83. They did not mail the sight blades however and instead just put them in the box with my completed M83 which arrived at my home on Thursday afternoon. Yep, you counted it right, shipped, modified and returned in 8 days. Not 8 working days, but 8 days. All I can say is WOW and of course a great big THANK YOU to all the folks at Freedom Arms.
