I spoke to Karl at Steyr and there are zero plans for importing the AUG or making it here. Impact is well known for taking pre orders on things like this. They are really assembling a wish list. AUG prices have come down some, and the magazines are definitely cheaper nowdays. Ive used the AUG alot and like it. It is a super reliable and accurate rifle and the quick change barrel is the best in the business. The only negative on the AUG is you are limited in your sighting options as there is no rail. That doesnt bother me as the standard AUG is equipped with an excellent Swarovski made 1.5 optical sight, which is replaceable. You can purchase a USR, which is a (limited) post ban AUG and does have the A2 picatinny rail under the optical sight. All the parts are interchangeable with the AUG.
Ive not seen the FN product, but until it actually appears in quantity, I dont think its that realistic. The AUG has been in Austrian Bundesheer service since the late 70s and has proven to be reliable. I've been buying magazines for 35-40 dollars lately which is not bad at all.
The other 5.56 weapon Ive been very impressed with is the HK G36. I used one overseas a good bit and have had two built here. They are available as conversions from SL8's here but run 2500+ in general. This weapon has been in Bundeswehr service since 1995 and has proven to be extremely reliable and accurate. It is a modular weapon, you can swap mag wells in about 15 seconds and use M16 magazines if you wish. It also has a variety of rails, etc so you can put about any sight you want on it.
