It is good marketing. Yet remember the Rifle is the base platform of choice here. Personal opinion here I have. I hate the rifle like the ammo. The rifles used for the NGSW Carbine and LMG by TV are imho the weakest of the three offerings. That’s not me just blasting Bullpup rifles. It’s the form of bullpup they chose in ergonomics from my perspective. SIG has the best rifle and LMG here. I expect TV, SIG and Textron to continue development and offering of the NGSW technology and packaging to allied states post award. As I posted elsewhere the SIG package is already being pitched for Australia.
Okay, correction time. This didn’t age well. since I posted this more information has become available. I based my first assessment on guesses made off photos and what had made it into promotional videos. Since then Team TV allowed Task & Purpose to get some trigger time on the RM277.
I had assumed that the control ergonomics were closer to AUG, SAR 21, TAR 21. I was wrong.
The Charging handle is unique. It’s very long and very forward this is likely to accommodate both the bolt and the added length of the reciprocal operation of the barrel.
Magazine release is similar to the Desert tech MDR series or the IWI Tavor 7/X95. It’s located on the trigger guard just above where an extended finger would naturally rest similarly to what is found on AR15.
Selector is also AR style and again similar to the Tavor 7 and MDR.
Bolt release is unique. Previous versions didn’t seem to have this yet the version fired has a shelf located above the selector that is pushed to unlock the bolt. Both Tavor 7 and MDR use a tab located behind the magazine well, as both also having an HK style slot to lock the charging handle into.
The ejection port is again very similar to both Tavor 7 and MDR. A set of covers that can be swapped from one side or the other, however this doesn’t mean that the RM277 can go from right to left instantly, MDR has that ability but Tavor 7 needs a field strip to reverse some bolt parts.
Due to this I am forced to reassess my opinion, to I dislike the rifle and LMG but like the ammo. My assessment now is just an emotional distaste of this Bullpup primarily due to first the eccentric charging handle next the choice of a just extended length barrel and bipod added for the “Automatic rifle” version. Reason they went with a bullpup is logical, rational. They wanted to keep the overall length close to that of an M4 well milking every possible PSI boost they could get from a long barrel.
One more note here the teaming is hard to keep up on. True Velocity is about the only side that is clear cut on what they do. Yet this team is also Berretta, General Dynamics and Lonestar Future weapons.
*because of similar caliber between the Tavor 7 and RM227 as well as the virtually identical features between Tavor 7 and X95. I will only compare to Tavor 7 however true for one true for the other in this comparison.
Oh you thought I was done? No more because the other two bidders also have gone to YouTube.
Love this video set as they actually field striped the weapons. We see what is going on in the weapon. Teaming H&K (yes that HK), Textron, Winchester, LMT.
Operation resembles the XM8/HK433 rifle in terms of controls. Bolt release at the bottom of the trigger guard is right off XM8, selector off XM8, only major change is the charging handle off the 443 and the additional clearing rod.
Textron is also going cutting edge with a power rail. In some ways I view this as the son of the OICW program. Not a grenade launcher with a carbine, true but it is picking up where that program failed.
Open bolt weapon with semiautomatic option on the selector this means rather than the typical push button type safety you have a more rifle like switch. The Negev from Israel also has a semi option of fire as does the ultimax lmg. It’s still rather uncommon but it’s rather useful feature as it means you can now actually zero the weapon or fire more controlled than bursts. Unique top cover means that you don’t loose zero on a reload. Yet still very familiar with the the M249. No Quick change barrel but rate of fire is down anyway. Besides all these are going to have a digital fire control group (fancy scope).
Sig. yeah no team all in house.
built off their MCX M originally offered for the CSASS M110A1. The MCX SPEAR. It’s has a foldable stock which is unique from its competition. It’s controls are almost 1:1 M4A1 you could drop this into the hands of a current soldier and just start shooting. The only changes ergonomic wise are a second left side non reciprocal charging handle and the duplication of magazine release and bolt lock on the mirrored side. (Leftie friendly) even has the stupid button (forward assist plunger). Function wise SPEAR and M4 are very different MCX is a short stroke gas piston gun. M4 uses what is either dubbed a Direct impingement system or an Internal piston system. The difference is that in M4 gas siphoned up the gas tube pushes on a piston face that is part of the bolt carrier group. In MCX it hits the piston cup on a separate piston that then hits the BCG.
In the RM277 video Cappy makes a comment that troops getting that weapon probably would have any other. That’s actually so wrong that even the army has pushed back. M4A1 and M249 will likely remain in service for at least two more decades. With M4(A1) Carbine and 5.56x45mm hanging around in its original intended role as a PDW. The SIG MCX base means that down the line if the army decides to tailor M4A1 even more to that PDW mission a weapon for cooks, Vehicle crews, book keepers and second line guys who don’t need the AP. Then dropping an MCX package might make cross training as easy as a hading the soldier a magazine to shoot. It’s so similar to the existing AR platform that Sig is saying that the weapon could be rechamber to 7.62x51mm. Again as the receiver sets were designed for the CSASS a 7.62x51mm rifle. This may mean down the line the army could decide to move up to a 25 round magazine and use off the shelf Pmags.
Like the Textron bid it’s a short barrel, 13” this is to give it an M4 overall length about comparable to a 16” civilian AR. When you consider the added receiver sand hinge length. Since all three have to show a can that will quickly get to M16 length. Also power rails for everyone!!
Now for more details on the SPEAR
Of course a second variant the LMG 68.
Sig basically developed the .338 Norma MG338 this gun is its sibling. It has an option for a Quick change barrel but the Army doesn’t want that for NGSW at least not yet. The barrel does reciprocate to try and buffer recoil like the TV guns. Sig and likely Textron both view these as options to replace both the M249 and M240B/M240L machine guns TV is pushing retrofit to the latter. At least in theory other M240 based and 762x51mm guns could be retrofitted with 6.8x51Fury though not as easy as the 6.8 TV. Both Textron and Sig can be loaded with the feed tray closed. Left side folding none reciprocal charging handle
However this gun can also be rechambered to 7.62x51mm which being still more common allows easy access for volume of training ammo.
