Testing the SureFire OBC Bolt Carrier Group
This video tests SureFire's OBC (Optimized Bolt Carrier) system for AR-15 platforms. The description highlights the OBC's innovative design, including new bolt carrier geometry, a rebounding counterweight, a redesigned gas key, a shorter buffer, and a new buffer spring. These features aim to slow the Bolt Carrier Group (BCG) down, increasing the time available for the system to strip and load the next round, potentially improving reliability. The content promises relevant, honest, and unfiltered in-depth gun reviews and tests.
