Raptor Charging Handles For Your SIG MPX Or MCX

Does your MPX or MCX suffer from flacid charging handle syndrome? Are you embarrassed by the rather small size of your chargng handle latch? Well Radian Weapons has the solution for you! Presenting the new Raptor Charging Handle for the Sig MPX and MCX.

The factory MPX and MCX charging handles are based on AR-15 style charging handles. And while they work as intended, they are somewhat small and droop. Yes, I said droop. The MPX has a slight problem keeping its charging handle straight and errect when extended to its full length. Due to this droop, the bottom of the charging handle scrapes against the top of the receiver. Thus marring the finish.

Why Get A Raptor Charging Handle?

I will let Nick Booras of Radian Weapons explain it.

The Raptors for SIG MPX and SIG MCX have been in development for over a year, but have been delayed due to engineering resources being allocated to more pressing projects, including the recently released Raptor-LT. We started with the MPX because of the growing popularity of the platform in the U.S. commercial market – it’s a great gun, but the non-ambidextrous charging handle in my Gen 1 MPX left something to be desired. We decided to tackle the MCX as well due to increasing adoption of the weapon by U.S. and allied police and military units. SIG’s product management team was extremely helpful in providing the necessary data to allow us to properly design these products and ensure compatibility with all generations of both full and semi-automatic MPX & MCX platforms.

I can attest to the non-ambidextrous charging handle on the Gen 1 MPX. I upgraded mine to a Gen 2 MPX charging handle so it was ambidextrous. However this was a stop gap as I was waiting for the Raptor charging handles to come out for the MPX. I have a Geissele, Next Level Armament and Raptor charging handles on my AR-15s. And I honestly prefer the Raptor of the other extended charging handles. While the Geissele and NLA handles are enlarged as well as ambidextrous, the ears or wings of the charging handle are a bit pointy. It is easy to snag them on gear.

Take a look at these comparison photos of the factory MPX charging handle against the Raptor charging handle. Raptor on the left and factory on the right. Notice how far the latches stick out from the side of the receiver. Much easier to grasp.

The MCX looks almost identical however the shaftis actually longer than the MPX.

So what about the droop in the factory charging handles for the MPX and MCX? Well Radian has a solution for that. All their MPX and MCX Raptor charging handles come with a replacement enhanced recoil spring block.

See that little ledge that protrudes upwards? That is what keeps the charging handle straight and erect.


No more drooping charging handles. Thanks, Radian Weapons!
