No Mutants Allowed

Not really. 100 years from now the AR-15 will be quaint.

IAR M27 is not exactly comparable to the original AR-15. Although given for something like CZ Bren 2, I would love for that rifle as replacement. Or that NGSW rifle that shoot 6.8x51mm

What, is this a prank? You're just showing me MORE AR-15 clones, with NATO mags and 5.56 ammunition!?

I kinda get it, since it's all standardized within the alliance, but it's precisely this streamlining that bums me out. It's not practical to deviate from certain standard; so we won't - even to the point where it disincentivices innovation. Last time someone tried something ballsy was G11, P90 I also like FiveSeven and MP7 approach to ammunition and defense.

These are all 20+ years old now though

I did mentioned CZ Bren 2 though. Polymer brick with two barrels.

And let's face it, the only way to revolutionize an assault rifle is to make them firing electrothermal chemical-plasma fuse. With maybe exploding bullets.

Ukraine war has shown what you really wanted is kind of modular platform that can shoot wide range caliber. So CZ Bren essentially. Not M4-WAC-47

Bred 2, too similar - looks just like SCAR! Although I might give old FN F2000 a pass, just for looking futuristic enough for 2001, despite using the most boring magazines in the universe

@zegh8578 CZ BREN 2 is based on the 805 and 807 pattern, which were released at the same time as SCAR. But CZ Bren ARs are actually less sophisticated than SCAR in term of gas operation, being just similiar in term of shape. But in term of modularity to accept all kind of caliber, CZ Bren triumph.

Regarding gas operation, apparently SCAR can support the subsonic version of given caliber to perform limited semi-auto. Ussually most rifles would just simply need to be cocked manually for each firing. Lighter bolt, concentrated piston push, yada yada.

SCAR is also ambixdexterous.

Doesn't that just mean that the necessary switches appear on both sides of the weapon? That's not exactly high tech, if not a bit wasteful in terms of material, since a single shooter will have a dominant hand, and won't have to access both sides of the weapon regularily - sticking to one side only.

In those cases, I believe most models, including old fashioned ones, can be refitted. Our G3 rifles certainly could, left-handed shooters got the safety switch moved to the opposite side That's a 1960s weapon

If you are US Rangers, apparently there is no such thing as dominant hand. All hands and cheek position get used when firing from variety of cover angles.

That sounds apocryphal to me
Like the US Rangers got some trick up their sleeve, that no other military force in the world could crack - despite evidently being fully aware of the US Rangers and their special ability

Apparently because US Rangers were the first customer for SCAR, at least the SCAR-17? Granted they use them more as DMR so that would explain why the whole rifles being justified to be adopted. But really why would other armed force would have more refined technique than the one who adopt it first?
