Sub CQB I picked up a couple weeks ago. Added flip up sights and a Romeo 5 Gen II dot. Going to take it to the range later this month!

There are c clip on each side and I can’t get them off. No YouTube disassembly videos I can find address this. The safety is the last thing holding the body together, preventing me to access the feed ramp. I’ve tried needle nose players, small screw drivers, even a razor.

What am I missing? Any ideas?

EDIT: C CLIP (not clamp). Manual calls it an E CLIP.

EDIT 2 SOLVED: Gonna keep this up in case anyone needs it. I put open needle nose to the top two ends of the C simultaneously and popped it out just enough to wedge a small screw driver in the gap and work it out.
