I really wanted to like this - Smith Tactics Side-Kick Co-Charger

This thing is a super neat idea if you have to mount a scope in a way that obstructs charging ergonomics. The folding side handle is great and forward retention is done through a ball detent reather than a clip. Now, I don't know if there's a specific receiver it's intended for, but my co-charger stuck. Hard. I backed the tension off the side detent to no avail, then noticed a larger ball detent on the bottom of the rear handle that kept hanging up on the buffer mount. Not seeing a means of adjustment nor the necessity of it, I worked some Dremel magic and removed it. Operation is easier now but it rubs so hard on the right side it's practically sanded all the finish off itself and grabs inside the raceway making charging a very sticky operation requiring a lot more force than it should. I really want to recommend this but I honestly can't if I'm having this much trouble with it before even getting to the range, unless there's SOMETHING I'm doing wrong.
