Gents have gotten cracked in the thumb by the OEM unit as well - to the point where the weapon choked. Just be mindful of any reciprocating CH, regardless of whose it is.One this to watch out for. I bought two - one for the 16 and 17. Solves all the knuckle issues. Great product.
But if you run with one hand on the magwell like we sometimes do - keep your thumb down or it will get smacked pretty good.
Old AR15 habits are hard to lose. Probably why FN went with the charging handle they have.
Do you run an E.A.C.H. on your SCAR?Yep, if you shoot right handed and you have a reciprocating CH on the left side, you're always going to have to think about where your forward hand is. A longer or angled downward one may be even worse. One of the downsides of the design, I think.
