Photo of the F90MBR (Modular Bullpup Rifle) In The Wild [DSEi 17]

The Steyr AUG is not dead! The latest iteration, the Thales F90MBR (Modular Bullpup Rifle) was announced just before DSEi and as expected was on display. Our good friend Lionel took these photos of the modular bullpup.

The F90MBR is claimed to be one of the lightest assault rifles out there at 3.25 kg (or 7.17 lbs). Given the extreme modularity of firearms today, it is hard to know how to compare weight of one with another (equal barrel lengths? same caliber? with muzzle device or without?).

Its upper and lower-style configuration allows it to be easily reconfigured with a new barrel length, optics and other accessories in a manner faster than competing bullpups such as the IWI Tavor.

Thales have focused on the F90MBR’s Over The Beach capabilities. The gun is ready to fire immediately when emerging from water, no draining the barrel required.

New Zealand has abandoned the Steyr AUG, but Australia have doubled down on it and the F90 is the result. I have spoken to a number of people who have handled the F90 and it is by all accounts a good rifle and a worthy successor to the old-school AUG, but it will be interesting to see how it fares in a world dominated by the AR-15 on one side, and the IWI Tavor on the other.

    I'm not one for bullpups but I appreciate the concept/design of them. Then we have this... the bane of the bullpup world.

      @mechamaster Not much you can do to the charging handle without major rework (I'd move it to where the vents above the grip are).
      However, there is room down the left side of the TMH to put a link rod for a safety/selector (removing the push-button safety and having the selector in an AR-15/Tavor sort of location). This would probably require redesigning the bolt hold / release (Tavor / MDR style?).
      I was recently wondering if it could be fitted with an ARX160 style CH slot cover (the one mounted on the return rod/spring), that would go a long way to stopping muck getting into the working parts and is potentially a cost effective upgrade.

    A lot of folks are down on bullpups, but with the USMC looking at suppressed carbines in a world of mechanized and airborne infantry and door kicking urban warfare, I suspect we'll see the bullpup return in popularity at some point in the future. It's the only way to get a battlefield usable barrel length (say at least 14.5 inches) with at least 6" of suppressor on the end and still be short enough to not be a return to the M16 pole vault.
