So, defresh me... Is a short barreled rifle $200 or $5?
SBR and SBS is $200. AOW's, pen-guns, belt-buckle guns, and shotgun pistols built on a "virgin" receiver are $5.
Although it might be awhile or never when we'll see the "Glock Carbine". Magpul seems to be trying to become an R&D/design company and license out stuff to other makers, like the Masada ---> Bushmaster ACR.
Magpul likes selling to civilians, they're smart enough to not turn away paying customers, but whoever picks up the licensing for this baby may not be.
