Description

The Alpha Fixed Beam Side Folder is Midwest Industries' answer for anyone running a 1913 Picatinny stock adapter who wants a folder that feels bank-vault solid. It bolts up to AR-15s, AKs with a 1913 adapter, the SIG MCX, and pretty much anything else sporting that rail interface. The whole thing is built from high-strength polymer, aluminum, and steel, and it ships configured for standard rifle use right out of the box.

What Makes the Alpha Side Folder Hold Up

The folding mechanism is machined from 4140 heat-treated steel with a full-length locking lug, and that's the part that matters most on a folder. You get a solid, positive lock-up in both the extended and folded positions, so there's no annoying wobble when you shoulder it. The steel clamp grabs the rail with a large surface engagement, which keeps things planted under recoil. Folded, it only adds about three-quarters of an inch to the firearm, and open it adds roughly 8.5 inches of length. The complete stock tips the scales right around a pound and a quarter.

Dialing In the Alpha Fixed Beam for Your Setup

Comfort is where this stock earns its keep. The adjustable polymer cheekpiece and curved top surface let you set your cheek weld exactly where you want it, which pays off when you're running a higher optic or a prism scope. The adjustable butt pad slides to your length of pull and works well when you've got a plate carrier or heavy gear on. There are three QD sling sockets built in so you can rig it up however you carry.

Lefties aren't an afterthought here. The Alpha is fully reversible and can be configured to fold on either the right or left side. If you'd rather run it as an arm brace setup, it's compatible with the Gear Head Works tailhook once you swap the beam. It's made in the USA and backed by a lifetime warranty, which tells you Midwest stands behind the build.

Frequently Asked Questions

What does the Alpha Fixed Beam Side Folder attach to?

It mounts to any firearm running a 1913 Picatinny stock adapter, which covers AR-15s, AKs equipped with a 1913 adapter, the SIG MCX, and similar platforms. The steel clamp grabs the rail with a large surface engagement for a secure hold. You'll need the 1913 adapter on your firearm first, since this is the stock, not the adapter.

Can the Alpha side folder fold to the left for southpaws?

Yes. The design is fully reversible and can be configured to fold on either the right or left side. That flexibility makes it a solid pick for left-handed shooters or anyone who prefers the folded stock clearing a particular side of the receiver.

Does the Alpha Fixed Beam stock wobble when locked open?

No. The 4140 heat-treated steel folding mechanism uses a full-length locking lug that gives you a positive lock-up in both the open and folded positions. Users consistently note the lock-up feels tight and solid without slop, though the hinge can feel a touch stiff when new and loosens up as it breaks in.

Can I run the Alpha as an arm brace instead of a stock?

It ships configured for rifle use, but it's compatible with the Gear Head Works tailhook if you want to swap the beam for an arm brace setup. Midwest offers a cosmetic plug separately to keep the back beam smooth when running it that way.
