Grip Mount Puller Instructions
General
The Grip Mount Puller consists of the Body, Plate, Bolts (6), Hammer, Shaft and
Nut. This tool is a slide hammer design in which the Hammer is slammed against
the end of the Shaft, driving the grip mount, which is clamped in the Body/Plate
assembly, out of the receiver. The grip mount must be pulled straight out the
front end of the receiver. Nothing but the barrel and friction hold the grip
mount in place. That is not to say that the grip mount will fall out of the
receiver. For a proper fit, it should have been driven into the receiver with
force when installed. After having been there awhile, dirt and rust may add to
holding the grip mount in place. It is critical to remove it without bending or
damaging its projection that fits behind the barrel (which is how it is held in
place) or damaging the front end of the receiver.
Grip Mount Removal
The barrel MUST be removed from the receiver before the grip mount can be
removed. Also remove the forearm or foregrip. Remove the Plate from the Body.
Place the Body under the grip mount with the Shaft and Hammer out front of the
receiver. Place the grip mount in the slot in the Body. Place the Plate on top
of the grip mount and bolt it to the Body, clamping the grip mount in the Body.
It is best to hold the receiver above the Puller by hand so that the Puller
hangs downward. This will eliminate stressing the receiver or grip mount. While
holding the receiver with one hand, raise the Hammer up the Shaft with the other
hand and then slam it downward. Unfortunately, not having a third hand to hold
the grip mount, the Puller and grip mount will probably end up on the floor so
take that into consideration by having the end of the Puller close to the floor
to begin with and maybe a little padding. The critical consideration is not to
put any bending stress on the grip mount.
Grip Mount Installation
The Puller can be left on the grip mount and be used to drive the grip mount
into a receiver by slamming the Hammer in the opposite direction. However,
always be sure there is no dirt or other obstruction in the receiver pocket. It
is critical that, when in installing a grip mount, the projection on top of the
grip mount which goes into the slot on the front face of the receiver, ends up
flush or below flush with the receiver face. The installed barrel must not rest
on the grip mount projection when it is installed.
