This new Data Card Holder System is designed to be
used on any MPA full size chassis (MPA BA Chassis, MPA Comp Chassis) to provide
a quick and effective method of viewing your DOPE for target distances while
keeping your cheek welded to the cheek riser.
The system attaches to any of the six oblong slots on
either side of the magazine well. The system provides multiple methods of
removing from the chassis.
- Using
the included Allen wrench, loosen the set screw in the “Chassis Mount”
component and slide the unit out of the oblong slot.
- Unscrew
the “Wire to Chassis Mount” and remove the entire assembly, less the
“Chassis Mount” which will stay attached to the chassis.
- Unscrew
the Thumb screw that holds the data card in place.
The data card has a surface similar to a dry erase
board. You can use either a grease pen, a dry erase pin, or we recommend a
“Crayola Washable Marker” which tends to leave the markings in place on the
data card even when you make subtle contact with the board (dry erase markers
are too easy to rub off). When its time to replace your data, simply wipe off
the markings with a cloth or paper towel. The shooter also has the option of
putting painters tape on the card and removing when the stage or shooting
session is completed.
The data card is designed to be removed by unscrewing
the Thumb screw that holds it in place. The card can he oriented top to bottom
or left to right. This gives the shooter multiple options for card placement as
well as the ability to write the DOPE on the card while not attached to the
rifle.
There is also a hole cut into the data card that is
designed to hold the allen wrench (5/64) in place while shooting. The wrench
has a special treatment performed on the shank to keep it securely in the hole
while shooting or moving the rifle.
The wire is flexible and has strong “obedience” (the
ability to stay in any position you bend it). It is simple 12 gage solid electrical wire.
