The AUG Special Receiver
So what is so "special" about the Special Receiver? The fact that it has a fixed rail in place of the optics! One complaint that was heard from some of the AUG's detractors was that the fixed 1.5x optic limited what you could do with the rifle, and that if the optics failed, you had no way of aiming the weapon (never mind that they didn't bother to notice the fixed iron sights on top of the optics housing).
The SR version of the AUG has no backup iron sight system and the user must supply the aiming device. Depending on the optics and configuration, the AUG can serve as a short range precision rifle, or as a LSW (Light Support Weapon) when fitted with the 24" heavy barrel as shown above. Steyr literature lists the 42 round magazine as being sufficient to provide "sustained" fire in the LSW role which is debatable, but it does offer 4 more 3 round bursts than the 30 round magazine and does not weigh the rifle down too much or make it difficult to maneuver.
|A close-up of the SR shows that the rail employed is actually different from the one used on the A2 and USR. I personally have no experience with this configuration, but I am sure other members can fill us in on what optics can be mounted and how they can be mounted. Trijicon's successful ACOG line of products has a dedicated mount, and their TA01NSN also includes a backup iron sight to boot!|
Amongst collectors in the US, the special receivers are highly desirable considering the limited number brought into the country. Although there are no matching number SR AUG's in the US, a complete gun such as the one pictured below that is "NIB" commands a premium that is close to the price of some of the less expensive used A2 AUG's!
