Shooters with longer arms or those running magnified optics often find factory fixed stocks coming up short on Length of Pull (LOP). A short LOP forces you to hunch over the receiver, crowding your optic, ruining proper eye relief, and creating unnecessary neck strain during long sessions behind the rifle.
The Magpul® PRS® Extended Rubber Butt-Pad 0.80" (MAG350) provides a clean, direct solution to customize your stock ergonomics. Designed as a direct swap for the factory pad, this 0.80" thick profile adds approximately 0.5" to your total Length of Pull. The resilient rubber matrix dampens shoulder impact while providing a positive, non-slip interface against tactical gear—ensuring consistent, repeatable eye placement behind your glass shot after shot.
Key Features & Technical Highlights
- +0.5" Length of Pull Extension: Replaces the thin factory pad to increase LOP by roughly half an inch, allowing taller marksmen and long-armed shooters to achieve a relaxed, natural cheek weld.
- Optimised Eye Relief Alignment: Prevents optic crowding on precision setups, helping you hit the eyebox of high-magnification scopes quickly from prone or bench positions.
- Tough High-Traction Rubber: Molded from chemical-resistant synthetic rubber with structured surface grip to prevent stock rotation against plate carriers, jacket material, or wet rain gear.
- Official NSN Designation: Awarded NSN 1005-01-591-5976, verifying compliance with stringent military supply standards for durability and environmental resistance.
- Direct Hardware Fitment: Installs in minutes using the existing screws from your original stock assembly.
