But, why is it called a Hinge Blaster? And why the two superfluous Hinges on Onslaught's legs?
In Vehicle Mode, Onslaught takes his new Hinge Blaster and turns it into a new attachment point for the green blaster!
The 5mm peg hole lets the green blaster attach to the back, right between the Hinges! No more stressed plastic, no more attaching to those two fiddly pages on his arms.
(And yes, other 5mm weapons can be attached as well)

And in the spirit of Hinge Blasters everywhere, Onslaught finally doesn't aim downwards anymore! Unlike the original connection, which left the gun pointing at the ground, the new connection lets Onslaught aim up, up, up!

The Hinge rotates through 360 degrees itself, only blocked by the vehicle itself and the ground, so Onslaught can aim all the way back at cars behind him if he wants.
