Modular, meaning a 1 piece unit (cannot be disassembled from the upper receiever).

Modular design, or "modularity in design", is an approach that subdivides a system into smaller parts (modules or skids) that can be independently created and then used in different systems to drive multiple functionalities. A modular system can be characterized by the following:
(1) Functional partitioning into discrete scalable, reusable modules consisting of isolated, self-contained functional elements.
(2) Rigorous use of well-defined modular interfaces, including object-oriented descriptions of module functionality
(3) Ease of change to achieve technology transparency and, to the extent possible, make use of industry standards for key interfaces.
BTW, modular means means many interchangeable pieces.
I'm so glad that my 2 AR57 SBR's were approved prior to all this SB281 bulls%#t.
Got any pics? Trying to get some idea's..
