The P365-FLUX is another collaboration between Flux Defense and SIG SAUER. Together they have created a polymer version of the aluminum Flux 365 Raider. The result is a slightly lighter version which will come as a complete gun. However, Flux Defense plans on offering the Raider for sale as a chassis.

The Raider is a chassis which transforms the SIG P320 of P365 FCU, barrel, and Slide into a PDW. It can serve as pistol or incorporate a stabilizing brace or fitted with a stock and converted to an SBR. The brace and stock fold to the right side of the pistol and can be configured to automatically deploy when the PDW is drawn from the holster. It’s important to note, the P320 and P365 require different Raider chassis.

The P365-FLUX comes with a 6″ barrel which is the longest P365 barrel but is only intended for use with the FLUX variant. It is also outfitted with a polymer barrel shroud, front Picatinny rail beneath the barrel, and X-RAY3 day / night sights.

SIG is going to offer a couple of versions. The full-on Sentry model will introduce the 25-round P365 magazine to the market and will come fitted with a 21 round and 25 round mag. Additionally, the PDW comes with a concealable (yes, this thing can be worn inside the waistbelt) holster.

We are still unsure when precisely the P365-FLUX will be available. Right now it looks like late Summer.

This is a little bit of an unexpected treat. I was able to fire the Royal Marines L143A2 rifle which were purchased a couple of years for the Future Commando Force operational concept under Project HAY, but not announced until March of this year.

It’s a SIG MCX carbine features 5.56 NATO 12.5″ barrel, but there’s also a 300 BLK variant also in service.

As you can see in the photo released by the Royal Marines, this is how it is equipped for maritime operations, with optic and magnifier and suppressor.

Coming Winter 2025 is what SIG describes as the most durable AR10 platform on the market, the HYP rifle. The name stems from the rifle’s ability to handle the high pressures (HYP) from SIG’s composite case ammunition.

Like with the 516 G3 Mohawk, SIG took lessons learned from the MCX rifle and applied them to a gas impingement AR pattern gun. It features a steel cam path insert and steel feed ramp along with a chrome lined hammer forged barrel. In fact, the barrel has a QD muzzle device which accepts the MG68QD suppressor used on the Army’s Next Gen M250 machine gun. It’s also fully ambidextrous, mirroring the controls on the 516 G3 Mohawk.

I had expected the HYP to also incorporate the side charging handle found on the 516 G3 Mohawk, but they left it off of the HYP in order to keep cost down. Turns out, the HYP is $2000 less than the MCX-SPEAR, making it a great choice for those who want to take advantage of .277 FURY. As you can see above, it also uses the steel 20 round magazines for the M7 Next Gen rifle.

I increased the contrast on the photo of this gel block to give you an idea of the performance of .277 FURY. This commercial ammo features 150gr NOSLER Accubond bonded core bullets.

Additional calibers will assuredly follow .277 FURY, including the ability to fire HYP versions of .7.62 and others.

Coming Winter 2025.

SIG was actually considering retiring the 516 but when they did a design review, the decision was made to incorporate lessons learned and best features from their other rifle offerings on a third generation of the rifle. The result is the new 516 G3 MOHAWK.

For instance, this new version of the popular 516 incorporates a steel cam pathway reinforcement insert into the upper receiver along with steel feed ramps, both found on the MCX.

The carbine also uses the MCX bolt with its tapered lugs and firing pin latch which helps prevent slam fire. Additionally, like with the MCX, the forward assist can be removed and a plug out in place.

Another feature which found its way over from the MCX line is the left-side non-reciprocating side charging handle. The side charger is removable and they’ll offer an insert to fill the slot. Likewise, you can remove the t-handle charger and replace it with a clamp to seal the rear of the receiver, eliminating gas in the face.

They’ve retained the 516 G2’s short stroke piston system, but production models will have a new valve lever with three wings in order to make it easier to manipulate between the three gas positions.

The carbine’s 16” chrome lined hammer forged barrel has a 1:7 twist and features a muzzle device which eliminates flash as well as climb and is compatible with SIG’s suppressors. Expect an 11.5” option as well.

To improve ergonomics they have incorporated a set of fully ambidextrous controls as well as installing a right side, side lock/release. Meanwhile, it has a SIG Matchlite DUO curved trigger.

Another major improvement is the new free-float handguard. Gone is the old “cheese grater” full length Picatinny rails which have been replaced with M-LOK slots.

With all of these improvements, the 516 G3 might be a good candidate for the UK’s upcoming Project Graeburn, the SA80 replacement.

The gun was very flat shooting, even on full-auto, and has soft recoil making it very controllable and easy to quickly transition targets. If I was going to buy another AR, it would be this one.

Look for the SIG 516 G3 MOHAWK winter 2025.

Although it wasn’t part of the formal new product reveals of SIG NEXT, the defense team showed me a 10″ upper for the US Army’s M7 Next Gen Rifle.

Seen to the right is the standard 13″ barrel length version which is currently under contract.

While the model I fired was equipped with the folding stock knuckle, they told me they have demonstrated a carbine version of the M7 which has a standard AR-style collapsible stock, eliminating the folding mechanism. Combined with a 10″ barrel, the weight is 7.3 lbs (without suppressor). By contrast, the M27 weighs 7.9 lbs and the standard M7 weighs 8.38 lbs.

With the shorter barrel length is a slight drop in velocity, to 2850 fps from ~3000 fps for the current M7.

SIG has dipped their toe in the double stack pistol market with the new P211.

First and foremost, it uses P320 magazines so finding mags won’t be an issue.

The slide comes ROMEOX PRO SIGLOC Equipped and features aggressive slide serrations.

The 4.4” Bull Barrel is fitted with the MACH3D Compensator.

It’s got a SIGLOC PRO Optic Ready Slide with Aggressive Slide Serrations and Ambidextrous Slide Release.

The Steel Frame and Alloy Grip module incorporate G10 Grip Panels and a Removable Steel Magwell and a Skeletonized Flat Blade Trigger.

Ships with (1) 23rd and (2) 21rd P320-Compatible Steel Magazines.

I got to shoot it a little bit and it remains stable through the shooting sequence and easy to keep on target. Part of that is that it is 9mm and part because it weighs in, in excess of 46 oz. It was a joy to shoot.

In stock and should be shipping VERY soon.
