Having to send it in for possible Warranty Work
Well I got my SU-16C apart but could not get the charging handle install. I fussed with it looking repeatedly at the manual and the online videos until I was ready to take the soft hammer and Dremell tool with grinder bit to it. I've packed it away to keep from going crazy on it.
It seems that it is taking them about 8 weeks to do their warranty work for the SU-16, and I spent to much money on the rifle and accessories so I can't afford to ship it until December. So I figure I wont get it back until late February of 2017.
At least by then I will have enough brass cased 5.56 heavy bullet NATO to break it in before I try to take it down. It may get a bit smokey at the range but until I get about 300 rounds through it, a bore snake will have to do for cleaning.
