At long last 651 is complete. Almost. The rear takedown pin and or the rear lug on the upper will require a bit of work (fit is a smidge off). Otherwise quite pleased. Colt upper,barrel,BCG etc..
The Duracoat Colt Grey is a much better match than I had anticipated. Love the 14.5 with th pinned & tigged extended flash hider. Sorry for the lack of photos my battery died.
Would be glad to post more if anyone is interested.
