Description
The Midwest Industries Alpha Series Fixed Beam Stock is a no-nonsense upgrade for rifles and short-barrel platforms running a 1913 rail adapter. Made from high-strength aluminum, polymer, and steel components, this fixed stock brings serious durability to the table without unnecessary complexity.
Alpha Fixed Beam Stock Build Quality
Construction is where this stock shines. The beam and attachment clamp use 4140 heat-treated steel for strength that won't quit, while the curved top surface is designed specifically for a solid cheek weld. A full-length locking lug keeps everything locked down tight with positive engagement in both positions. No wobble, no flex, just a rock-solid platform.
Adjustability and Comfort
The adjustable polymer cheekpiece and butt pad let you dial in your setup for your body and gear. Need to shoot with body armor? The butt pad adjusts for plate carrier use. Running a low-mounted optic? The cheekpiece gets you to the right height for proper sight picture. This flexibility makes the stock work across different platforms and configurations.
Practical Features for Real Use
Three QD sling attachment points give you mounting options on either side of the stock, and the reversible design means it works left or right-handed out of the box. The stock adds 8 inches to overall length and weighs just 13.8 ounces, so it's not going to bog down your rifle. It ships for rifle use but is also compatible with arm brace accessories for pistol platforms if needed.
Made in the USA with a lifetime warranty backing your investment.

Frequently Asked Questions
Will the Alpha fixed beam stock work on my AK-pattern rifle?
Yes, as long as your rifle has a 1913 Picatinny rail adapter installed on the rear trunnion. The stock mounts directly to this standard interface. If your rifle doesn't have a 1913 adapter, you'll need to install one first, which is a straightforward process on most AK-pattern rifles.
Can I adjust the cheekpiece and butt pad?
Both the polymer cheekpiece and rubber butt pad are fully adjustable. The cheekpiece lets you dial in the height for your optics setup and sight picture, while the butt pad can be adjusted for comfort with or without body armor. This makes the stock adaptable to different shooting positions and gear configurations.
Is this stock reversible for left-handed shooters?
Yes. The Alpha fixed beam stock is designed with a reversible configuration, so it works for both left and right-handed users without modification. The sling attachment points and overall design function equally well regardless of which side you shoot from.
What's the difference between the fixed and folding versions?
The fixed beam stock is solid and non-folding, offering maximum stiffness and a compact profile. The side-folding version adds a heavy-duty folding mechanism for compactness when needed, but weighs slightly more. Choose the fixed version for dedicated rifles or the folding version if you need portability or storage space.
