P90/PS90 Cheek Riser (Gen 4)

Product Description

Introducing the Haga Defense Gen 4 lineup—a cutting-edge evolution of upgrades for the FN PS90 and P90, meticulously refined since 2014 to deliver unparalleled performance and innovation.

Elevate your shooting precision with our P90/PS90 Cheek Riser, designed to address the firearm’s high height-over-bore (HOB). HOB, the vertical distance between the barrel’s center and the optic’s center, can misalign your eye with the optic when maintaining a proper cheek weld. Our Cheek Riser raises the cheek weld by nearly an inch, aligning your eye with your optic for improved accuracy and consistency, making it an essential upgrade for any P90/PS90 with an optic.

Crafted from durable, lightweight nylon with a sleek black finish, this cheek riser features a built-in steel QD sling mount and an MLOK slot on each side for additional sling and accessory mounting options.

Key Features:

• Raises cheek weld approximately 1"
• Lightweight Design: Made from premium nylon, this cheek riser minimizes weight for improved handling and comfort during extended use. (4.3 OZ)
• Built-in steel QD sling mount. 
• M-LOK Compatibility: Equipped with an M-LOK slot on each side offering diverse mounting configurations.
• Easy installation.
• Made in the USA.

Installation:

1. Set the fire selector at the position ‘S’ (safe).
2. Pull the magazine catch rearward in order to release the magazine and then remove the magazine.
3. Pull the cocking handle completely rearward and hold it in that position. Through the magazine opening, look into the chamber of the carbine in order to ensure that there is no cartridge in the chamber.
4. If the chamber is empty, release the cocking handle.
5. Remove the two top screws and nuts at the back of the plastic stock using a 3mm hex tool. 
6. Slide the cheek riser onto the stock until the holes in the cheek riser line up with the holes in the stock where the factory screws were removed. 
7. If your cheek riser fits tightly, secure it using the screws and nuts included with the cheek riser. If your riser fit is loose proceed to step 8.
8. The stock on the new P90/PS90s is wider than the older ones. If you have an older model your riser will fit loose. To correct this insert the included washers between the riser and the stock on each side while installing the new screws and nuts.
