The wait is over...our new 21" and 20" Adapter Rails in black anodized finish are finally available for purchase on our website. Also, our new Shot-LOC barrel shrouds are also now available for purchase on the site, to. These Shot-LOC shrouds are intended to possibly replace our popular Integrated Shrouds with the attached picatinny rail. The new design allows you to attach multiple rails at 180 degrees apart, on either top and bottom or, left and right sides. Less pricey to get started, and lighter in weight, too. As a heads-up, some additional brand new, never mentioned carbine products are gonna be released next week. Stay tuned for those, cause they are definitely different! j.
