After waiting 7 months to get my upper and complete my build I finally shot it today at the range.  First 150 rounds were flawless.  Then after shooting a few rounds i noticed the charging handle jump back about an inch, I locked it back in place, happened two or three more times about 10-15 rounds apart.  Then I notice, although it feels and sounds like the handle is being locked back into place when i push it, it is actually sitting on the very edge but the latch isnt locking into the upper receiver groove.  I thought it might be my BUS so I moved it forward, still wont lock,  I cant see it catching on anything so now I get to call Rock River on monday and explain the problem to them.  Anyone ever see this???

Something is out of spec.  Do you have acess to any other charging handles you could try out?

Unfortunately no, not right now, I might be able to borrow one from my armory for a few minutes on Monday

Yup. I had that same exact problem with a CMT/Stag charging handle. I tried it on multiple uppers but it wouldn't latch... I had to replace it.
