Fiberforce Marlin Stock

Why Choose the ATI Marlin Fiberforce Thumbhole Rifle Stock?

The ATI Marlin Fiberforce Thumbhole Rifle Stock is designed for owners of compatible Marlin .22 rifles who want a more ergonomic, weather-resistant replacement for a traditional factory stock.

The MAR3000 combines a thumbhole grip, built-in cheekrest and ventilated forearm in a lightweight one-piece stock designed around several of Marlin’s most established semi-automatic rimfire platforms.

Thumbhole Grip for Improved Control

The Fiberforce stock uses a thumbhole-style grip that gives the shooting hand a more defined and consistent position.

This design provides additional leverage and control compared with many traditional straight-grip rifle stocks while maintaining a comfortable shooting position.

Built-In Cheekrest

An integrated cheekrest provides a consistent contact point for the shooter’s face.

Because the cheekrest is built directly into the stock, there are no separate components to adjust or install, keeping the design simple and durable.

Ventilated Forearm

The MAR3000 incorporates a ventilated forearm and handguard design.

The openings help reduce unnecessary material while giving the stock its distinctive Fiberforce appearance and providing a comfortable support-hand area.

Lightweight, Weather-Resistant Construction

The stock is manufactured from reinforced synthetic material designed to withstand regular use and changing environmental conditions.

At approximately 26 ounces, the Fiberforce provides a substantial stock upgrade without adding excessive weight to the rifle.

Unlike traditional wood furniture, the synthetic construction is not affected by moisture in the same way, making it a practical option for rifles used in varying weather conditions.

Ambidextrous Design

The Fiberforce stock is designed for comfortable use by both right- and left-handed shooters.

Its symmetrical grip and stock configuration make it a practical replacement for households or shooting environments where the same rifle may be used by different shooters.

Designed for Popular Marlin .22 Rifles

The MAR3000 is designed for select Marlin semi-automatic .22 LR rifles, including compatible Model 60, Model 75, Model 990 and Model 995 configurations.

It can be used with supported tube-fed and detachable-magazine rifles.

The Marlin 795 is not compatible with this stock.

Because Marlin rifles were produced in multiple configurations over many years, minor fitting may be required on some models. Always review the ATI Fitment tab before ordering.

The ATI Advantage

ATI’s Fiberforce line was developed to give owners of classic rifle platforms a durable alternative to traditional factory furniture.

The Marlin Fiberforce Thumbhole Stock combines an ergonomic thumbhole grip, integrated cheekrest, ventilated forearm, lightweight reinforced construction and weather resistance into one complete replacement stock.

For owners who want to modernize the feel of a proven Marlin .22 while retaining the rifle they already know, the MAR3000 provides a distinctive and practical ATI-designed upgrade.
