I'm in the process of redoing my 6933.
When I first got it a few years ago I started out with a TA31 RCO on a Larue mount, three-prong Surefire flashider, Daniel Defense Omega rail, Magpul CTR stock then I ordered a black Surefire SOCOM556-RC suppressor.
Then I got bit by the Mk18 bug really bad and was able to actually cancel my order on the black Surefire can and ordered a tan one instead. I sold off the rail, ACOG and stock to fund the rest of the parts.
I got a Mk18 upper built by Ken Elmore at SAW with the whole works, DD RIS II, four-prong Surefire flashider, tear drop forward assist, KAC irons and I mounted a tan EOTech XPS3-0 on it. Also had a tan Surefire Scout light on there with a TD grip and flashlight switch and a tan Gen 1 Sopmod stock. Really the only thing I was missing on it was a tan PEQ-15.
I had that upper for several years but I think I enjoyed tracking down all the parts and getting the upper assembled more than shooting it. With all that junk on it, plus the can, the whole thing was kind of a front-heavy pig.
To get back to basics and go with an upper that was more pleasurable to shoot I took my original 11.5" 6933 upper out of the safe and ordered a ordered a TA33 with BOBRO mount and went back to the CTR stock to save a little weight over the Sopmod. I'm even back to the old slim-line plastic handguards too.
Everything about this rifle I just want to be lightweight and fun to shoot. I don't even plan on shooting it suppressed all that much. Ofcourse I've still got my Mk18 SAW upper, don't plan on getting rid of that anytime soon just because of how difficult it was to track down some of those parts. I did however mail back the EOTech to take advantage of the buy-back program to help pay for the TA33.
Once I get my ACOG on and get everything pieced together I'll put up some pics.
