Well it's been a long time coming but it looks like some stores are already taking pre-orders on the Masada PTS ACR (ASGI and eHobby for certain). a March release date turned into June, July and now August/September seems to be the availability date.
Looks like Magpul PTS put a lot of development into these AEGs with a feature oriented design and a great attention to detail. The initial release is going to be a standard black ACR (leaning toward the original Masada design) with a fixed stock, special type of version 2 gearbox, and a polymer front grip (though the exact contents of the package have yet to be determined). Dark Earth and Foliage Green are scheduled to be released at a later time. There are a series of photos released by Spartan Imports that showcase the extreme quality and attention to every detail of this AEG. The stand alone gun will cost you a "measly" 450 bucks. Optional components such as the extend-able fold-able stock, metal/railed front grip, changeable barrels, drop in GBB module (rumored), high caliber lower receiver (rumored), and other upgrades will undoubtedly cost a pretty penny as well.
If you're a fan of the ACR system and have the spending bread to drop on this gun and accessories, this just might be the gun for you. Other than that, it's just an AEG with an abundance of features that many players may not even use (and overpriced in my opinion). Regardless, retailers are recommending pre-orders as they believe the AEG will sell out quickly at release.
