Heat Rejection
Not only does the Brigand handguard withstand the heat
alignment but secure mounting. These components are the
same for all Brigand handguards; they weigh 2.66 oz. (Take
note that many manufacturers shrewdly neglect these
necessary components in their own weight budget!)
The EDGE handguard is offered in three lengths, to fit all
gas systems and all shooting styles. Because the carbon tube is
incredibly lightweight compared to the competition, longer
tubes mean the EDGE offers more and more weight savings.
BRAIDING is a time-honored process of
interlacing yarns together that is revolutionizing
the modern composites industry. Our braiding
requires large, specialized machines to handle
the high tension and precision required for
lattice structure tubes. We carefully inspect the
yarns and load the machine in the right patterns
– computers control the speeds and tensions to
ensure repeatable quality and dimensions.

of sustained firing, it also rejects barrel heat faster than most
handguards. Heat leaves a rifle barrel through convection (airflow past the barrel) and radiation (infrared ‘glow’). Brigand’s
open-architecture braid provides minimal resistance to airflow, allowing heat to be blown off quickly, and provides
excellent exposure to the open sky for radiated heat to
escape. Does this exposure mean your hand will get hot? The

We understand that lightweight weapons cannot sacrifice
any performance for weight-savings. After engineering to the
limit of performance, physical testing is a key part of validating
our designs. How strong is the handguard? We can hang 40
