As far as Magpul's direct involvement goes, we'll be designing and manufacturing all polymer ACR parts including, but not limited to, handguards, lowers, and stocks. The bottom line: you get high-end Magpul kit straight from the factory on your Bushmaster ACR.
A couple of things in closing - for those of you who are wondering, Magpul is still an independently owned and operated company. We will also continue to expand our product line. In the following days at SHOT we plan to release several new products. These are fast and exciting times for those in our industry.
One of Magpul's strong points is making polymer, so that part of the rifle should be just fine (and by just fine I actually mean really, really good. Has anyone ever played with one of their followers in a magazine, trying to get it to bind? Can't be done.)
And if you want to really see the internet at it's best, check out some of the other threads there. Arfcom reminds me at times of a little place that Virgil is said to give tours of.
Some people are not happy (decidedly non-THR sentiments expressed, be warned) that Magpul, which owns what, some lathes, a small factory or two, less than fifty employees and some injection molding machines will not be making the masada by the thousands.
In retrospect is seems obvious that they were going to have to take out huge loans to get the kind of equipment to make the product in bulk, or they were going to have to license it to somebody. And really, when you look out there, who else could you go to? Sure, there are other companies that would sacrifice their primary shareholders to get the rights to make the masada, but bushmaster actually has experience making things other than AR-15s.
As long as the QC is good, it's still a masada. Freeing Magpul to dream up other things is not a bad thing at all!
