Basic Info
...therefore, I must re-emphasize the necessity of making field practicality the prime design objective of any weapon — and that means the fuller grooves on 77 are obsolete and redundant features that serve no purpose! You must understand that our enemies neither bleed nor feel pain. Stop adopting design elements from those Rhodes Island engineering drawings.
Aesthetics?! I am taking that very personally, sir. The greatest virtue of any weapon lies not in its appearance! If I wanted to make things look nice, I would be working at Mieszko Industries and not at this blasted place!
