ATI Outdoors Enfield Stocks: The Ultimate Upgrade for Your Lee Enfield Rifle
ENF0041 & ENF0013 | Monte Carlo Replacement Stocks | Made in the USA
If you own a classic Lee Enfield rifle, you already know the legendary reliability and accuracy that made this bolt-action icon a staple of British Commonwealth forces for over a century. But after decades of service, many original Enfield stocks show their age — worn wood, cracked grips, and a look that says “museum piece” rather than “hunting companion.” That’s where ATI Outdoors steps in. With their purpose-built Monte Carlo replacement stocks, specifically part numbers ENF0041 and ENF0013, ATI Outdoors has created a drop-in solution that breathes new life into one of the world’s most beloved military rifles.
Why Upgrade Your Lee Enfield Stock?
The Lee Enfield rifle has been chambered in both .303 British and .308 Winchester, serving hunters, collectors, and sport shooters alike. However, the original wood stocks were designed for military function, not modern ergonomics or durability. Humidity warps wood, field use causes cracks, and decades of storage leave many Enfield stocks unfit for serious shooting. ATI Outdoors’ polymer Monte Carlo stocks solve all of these problems at once, giving your rifle a fresh, sporting look while dramatically improving functionality.

ATI Outdoors Enfield Stock Color Options
One of the most appealing aspects of ATI Outdoors’ Enfield stock lineup is the variety of color options available, allowing you to personalize your rifle for hunting, range use, or display. The Enfield Monte Carlo stocks are available in the following finishes:
- Matte Black — The classic, tactical finish that pairs well with any Enfield variant. The standard ENF0041 and ENF0013 are offered in matte black glass-filled nylon, providing a sleek, no-nonsense look.
- Woodland Brown — Both Enfield options available in Woodland Brown is a rich, earthy tone ideal for hunters who spend time in wooded or mixed environments.
DuPont Glass Reinforced Polymer: Built to Last a Lifetime
Both the ENF0041 and ENF0013 are constructed from DuPont Extreme Temperature Glass Reinforced Polymer — a premium material chosen specifically for its resistance to warping, cracking, and degradation under harsh conditions. Unlike traditional wood stocks, this polymer will not absorb moisture, won’t swell in humidity, and performs reliably across a wide temperature range. The result is a stock that maintains its fit and function whether you’re hunting in a cold Canadian winter or a hot Texas summer. ATI Outdoors backs this durability with a Limited Lifetime Warranty, a testament to their confidence in the product.
ENF0041 vs. ENF0013: How to Choose the Right ATI Enfield Stock
Choosing between the ENF0041 and ENF0013 comes down to one simple check — the location of your rear sight:
- Rear sight on the RECEIVER → Choose ENF0041 (fits No. 4, Mk 1, Mk 2, Mk 5)
- Rear sight on the BARREL → Choose ENF0013 (fits No. 1, Mk 3, and Ishapore .308)
Note that some minor modification may be required for a perfect fit depending on your specific variant. ATI Outdoors’ scope mounts (sold separately) are also available to complement your new stock and complete the sporting transformation of your Enfield.

They’re American-made, backed by a lifetime warranty, available in multiple colors, and install without a gunsmith.
