PRS2 (HK G3) Stock
Step 1: Confirm Part Type
First, confirm the HK-type interface has been included. Any
issues contact Magpul for a replacement stock at 1-877-4MAGPUL.
Step 2: Remove Original Stock
The PRS2 utilizes several pieces from the OEM stock. Remove
original stock per armory guidelines and disassemble. Confirm that the parts
are present: A. G3 Buffer Screw B. G3 Back Plate Assembly C. G3 Buffer,
Step 3: Fit Interface
Mate the PRS2 HK interface with G3 back plate. Note: This
is a snug fit and may require light tapping with a rubber mallet to ensure the
HK interface is fully seated in the G3 back plate.
Step 4: Install Buffer
Drop G3 Buffer in its original hole through the front of
the G3 back plate. Install ½” flat-head cap screw in top hole of G3 buffer
through front of G3 back plate.
Note: The screw will form its own threads requiring
additional force upon first installation. Install G3 buffer screw and large
washer through rear of HK interface.
Step 5: Mount PRS2 Stock Body
Drop square nut in slot on front of PRS2 body and mate with
HK interface. Drop 2” flat-head cap screw through bottom hole of G3 buffer.
Using 1/8” hex key, tighten until hand tight.
Step 6: Install QD Sling Mount
Mount cover plate in right-side slot of HK interface and
feed 1-1/8” button head cap screws through holes. Mount quick release plate in
left-side slot, making sure side with smaller diameter hole is facing out.
Tighten screws using 1/8” hex key. Parts may be reversed for left-handed users.
Mount stock per armory guidelines. Have a qualified professional verify proper
installation prior to loading or firing weapon.
Step 7: Shift Cheek Piece
The cheekpiece is attached to the stock by two screws and
may be adjusted forward and aft to accommodate different users. To adjust, use
a 1/8” hex key to loosen the top screws. DO NOT remove screws all the way as
this may cause small parts to come loose. Shift cheekpiece into desired
position and re-tighten screws with hand pressure.
This step is optional and not required for complete
installation of the PRS2.
