The AUG consists of six interchangeable assemblies: the barrel, receiver with integrated telescopic sight or Picatinny rail, bolt carrier assembly, trigger mechanism, stock and magazine. The submachine gun variants are chambered in 9×19mm Parabellum. Some nations including Australia, Ireland and New Zealand use a version with a 1:7 twist optimised for the SS109 NATO round. It is chambered in 5.56×45mm NATO cartridge and has the standard 1:9 rifling twist that will stabilise both SS109/M855 and M193 rounds. The AUG employs a very high level of advanced firearms technology and is made with the extensive use of polymers and aluminium components. It is designed as a Modular Weapon System that could be quickly configured as a rifle, a carbine, a sniper rifle, a sub-machine gun and even an open-bolt squad automatic weapon. The Steyr AUG is a selective-fire, bullpup weapon with a conventional gas-piston-operated action that fires from a closed bolt.

The ban sunsetted in 2004, and in 2008 Steyr Arms worked with Sabre Defense to produce parts legally in the U.S. Changes included the pistol grip being changed into a thumbhole stock, and the gun barrel left unthreaded to prevent attachment of flash hiders and suppressors. Six years into the ban, AUG buyers gained a reprieve as cosmetic changes to the carbine’s design allowed importation once again. Bush banned the AUG via an executive order under the 1989 Assault Weapon Import Ban. Steyr AUG importation into the United States began in the 1980s as the AUG/SA (SA denoting semiautomatic).

In production since 1978, it is the standard small arm of the Bundesheer and various Austrian federal police units, and its variants have also been adopted by the armed forces of dozens of countries, with some using it as a standard-issue service rifle. It was adopted by the Austrian Army in 1978 as the StG 77 ( Sturmgewehr 77), where it replaced the 7.62×51mm NATO StG 58 automatic rifle (a licence-built FN FAL). The Steyr AUG ( German: Armee-Universal-Gewehr, lit.'universal army rifle') is an Austrian bullpup assault rifle chambered for the 5.56×45mm NATO intermediate cartridge, designed in the 1960s by Steyr-Daimler-Puch, and now manufactured by Steyr Mannlicher GmbH & Co KG.

So if you have a F marked FSB, you can buy Flip-ups and Mil-spec carry handles. Bushmaster makes both the lower commercial sized carry handle and the taller front post. You just need to match your BUIS when buying a Carry handle as the picture I posted shows. In case you couldn't get it to zero properly, especially if you decide to set up the rear for revised improved battle sight zero, you could just buy a longer front sight insert. If you happen to already have an upper that has an A2, don't loose any sleep over it, it will work just fine. If you've got the choice, then I would get the F. Like I said in the post above your post, either would work, but the F marked would be the correct one for a flat top, as it is slightly taller.
