Hey guys. Had a YHM QD muzzle device I had previously rocksetted on that I needed to remove for repair. Placed my upper on a
Wheeler action rod and got the flash hider off.
Took a good bit of force but didn't use a breaker bar or anything, just a normal armorer wrench.
After I removed it, I couldn't get the upper out of the Wheeler rod... The rod has a lock/unlock function that twists the lugs like a bolt to lock the rod onto the barrel extension. I couldn't get it to unlock.
With a pair of channel locks I finally got the rod to unlock and got the upper out.
Upon inspection, everything appears OK... Barrel nut tight, gas tube and block seem aligned still, barrel extension lines up with m4 ramps... Bolt carrier group moves in and out smoothly. But this makes me nervous I tweaked something that made the Wheeler rod get stuck like that. Haven't gotten to shoot it yet.
Any advice here? Seen this before? Anything else I can check? Thanks for your advice.
