Being into mil-spec parts (m4, ACOG, etc) this was my first attempt to make a civilian "gucci" gun. Radian did not disappoint! Everything from packaging to craftsmanship and finish screamed equality. Took a while to be able to take it out and try it for real (due to COVID), and in practice, it shot flawlessly and after about 270 rnds, not even a scratch inside (even on the charging handle). It was very accurate from 25yrds (that was my max range limit) and created a touching group. But will update later when I could take it to an outdoor range.

Most important of all: it looks gorgeous!

BUYER BEWARE:
In the listing and the photo, the muzzle device is listed as "Silencer Co". What I received was actually "Dead Air Keymo" Flash Hider -- which is a far better choice, but I thought I should mention it since it's important to a lot of people.

We all know that a nice and smooth racking is half of the fun. But for the latest gen SIG MPX-K, I was really disappointed when I tried its gritty and uncomfortable charging handle.

Didn’t think Radian would help much but it made my pistol run super smooth. The coating on the handle (Teflon I think- don’t quote me on that) makes it interact very smoothly with a tiny amount of oil.

Can’t recommend enough!

I was originally disappointed to see how wobbly and loose the construction is, till I realized that once it’s mounted and pushed forward, it’s steady as a rock.

On top of that, not having super tight mechanics (like atlas, which has no wobble or give) is perhaps on purpose. It makes it far easier to manipulate and easier to resist jamming in case of a sand/water ingress.

Main reason to keep, it looks freaking cool! Atlas is commercial airliner, KAC is a stealth fighter jet.

And $450... Ouch!
