Bullet Drop Compensation (Bdc) - Primary Arms GEN II Instruction Manual

GETTING TO KNOW
YOUR BULLET DROP
COMPENSATION (BDC)
Gravity will affect your bullet's trajectory (or
path). The BDC ladder starts at the center dot
and finishes at the 800 yard mark indicated
by the number (8). Simply aim using the hash
mark that coincides with the range to target.
For targets at ranges between hash marks
you can split the difference. For example, for
a target at 450 yards you should aim halfway
between the 400 and 500 yard hash marks.
We recommend that you establish a steady,
supported position in order to utilize the BDC.
