On the MPX, the trigger and the charging handle are the weakest parts of the whole thing. The factory handle was thin and difficult to use, and it wobbled up and down, too. This is a fantastic improvement, and makes the whole experience much better; it's possible now to charge from the right side. I think it was before, kind of, but not a good experience. Just based on this I bought another standard 15 handle for another.

I have a Saint Edge with one of these on it, and liked it so much I bought more of them for other builds I'm doing. It's just very high quality, feels solid, and while hard does not feel cheap at all. The storage compartment opens easily, but not too easily, and it just feels great. It does come with the screw to hold it in!

I have the Ultra Duty kit on order, too, but that was out of stock, so I ordered the Standard Duty kit as it was in stock. My expectations were for a decent basic lower parts kit at the price, and that's what I received.

I will note that my kit had 2 safety levers (part 15) as well as 2 safety plungers (part 8). It did not have the hex key (part 19), but I don't think it is supposed to be included, as there's really not a use for it in this kit. So, I would consider it to be more than complete as I have a few spares. As to how everything feels, the take-down and pivot pins are smooth with added lubricant. The safety does take a bit more effort than one I would consider top notch, but it is by no means bad. The other parts like the bolt catch and mag release seem sturdy enough, but are not "premium", but you can get better kits. The roll pins needed a little press on one end with some pliers, and I did that so as not to have missed strikes and mar the finish due to a missed start. They stay put when you hammer them in.

As to speculation on who makes it, it is probably a mix of Geissele parts and some other more generic ones, and I'd imagine that to be the case with the Super and Ultra Duty, too. The 2 safety levers had the "G" on them, just like in the picture.

Overall, this will make me happy until my Ultra Duty kit comes in.
