Reliability and wear - TRYBE Defense Ambidextrous Magnite Charging Handle

I have 3 of these in AR15 and 1 in AR10, picked up on different occasions. I like the overall shape and function, thought I'd be able to use these in place of the nicer ambi handles that cost more.

I only get out occasionally, not a high volume shooter, so it takes me time to find issues, when they do occur. So far no issues with the 308 version, but that one gets far fewer rounds.

So far I've used 2 of the 3 AR15 size handles and both had issues. One of them started wearing out in corners where it hits the upper upon returning to battery. I've seen similar on cheap mil-spec handles that come stock with stuff. Ok.

Far worse issue with the other one - during a recent range session I noticed that it was difficult to rack the action back. Thought maybe cases were sticking, but it turned out one of the roll pins walked out, and began rubbing on the lower, and damaging it. It's gouged a "track" where it travels with the charging motion of the handle. The roll pin is so loose in there that you can pull it out with your fingers, if you can pinch it.

I am not down on "Trybe" products, I've had some good experiences, and posted good reviews, but have had some disappointments. This one damaged my rifle, so it's worse than a mere disappointment. I'll have to splurge on a Breek Sledgehammer - I've had very good experience so far with the War Hammers and Sledgehammer.
