The Magpul PRS2 (Precision Rifle/Sniper) - G3 model is a drop-in, precision-adjusting butt stock especially designed for the HK G3/91 rifle and variants.

Designed to offer the fine-tuned, customized feel of a precision target stock, the PRS2 is adjustable for both cheek riser height and LOP without sacrificing the durability necessary to withstand the operational environment.

The PRS2 has similar minimum LOP compared to common plastic fixed stocks, but it can extend 1.25” longer. Machined aluminum adjustment knobs feature positive-locking click detents to maintain position under recoil and allows easy, tool-less adjustments by rotating the knobs.

Machined aluminum butt-plate and alloy steel adjustment shafts provide stability and strength to withstand severe impact conditions. Rubber butt-pad offers positive shoulder purchase to prevent slippage for optimal accuracy even with body armor. Stronger and heavier than most OEM stocks, the PRS2 also adds beneficial weight to the rear of normally nose-heavy G3/91 rifles.

Sling Mount Rear – 1.50” sling  loop (left-right reversible)

         PRS2 (HK G3) Stock Install Instructions

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, Standard.

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.
