I just got my first MWS today! Picked it up a second-hand MWS CQBR M4 with a few mags at a decent price.
First thing off the bat, it’s beautiful, and all the mags are leak free.
A few strange things I’ve noticed, and I wonder if it’s normal or needs attention.
1. The bolt makes this pinging noise when dropped / shot, almost like a spring inside is moving around.
2. The upper and lower receiver has a gap between the two parts. The gap is large enough to look through and wobble around in the hand.
I watched Oil's video on using a hair band to fix it, but is there a more long-term solution?
