Description
The Midwest Industries stock takes the tried and true Remington 870 and drags it into the modern era without losing what made the platform great in the first place. The grip and stock beam are machined from 6061 aluminum with a hard coat anodized finish, so you get real durability that stands up to hard use. What you end up with is a stock that weighs about the same as the factory wood piece but gives you far more in the way of adjustability, texture, and control.
Why the Midwest Industries 870 Stock Beats the Factory Wood
The biggest upgrade here is the adjustable polymer cheek piece. Drop it to the lowest position and you keep the same height as the original factory stock, which is perfect if you're running iron sights. Raise it up and you've got a solid cheek weld for red dots or magnified optics, so you can build your 870 around whatever sighting system you prefer. Length of pull matches factory spec right out of the box, and if you need more reach, spacer plates are available as an add-on to dial it in to your frame.
Real-World Handling and Attachment Points
The MI-designed grip panels give you plenty of texture, which pays off when things get wet or cold and you still need a sure hold. Midwest didn't skimp on mounting options either. You get several anti-rotation QD swivel sockets, a standard sling swivel stud, and M-LOK compatible slots on both sides. Those M-LOK slots work with MI Universal Shell Holders if you want extra rounds on board, or panels if you're just after the look. The exclusive Midwest Industries butt pad rounds it out by taking the edge off felt recoil while keeping a secure fit in your shoulder.
The ambidextrous design means lefties and righties both get the same experience, and installation is straightforward for a home upgrade. If you've been meaning to modernize a well-worn 870, this is a clean, no-nonsense way to do it.

Frequently Asked Questions
Does this Midwest Industries stock fit all Remington 870 shotguns?
It's designed for the 12 gauge Remington 870 platform. The stock installs in place of the factory wood or synthetic stock using standard 870 hardware, so it's a straightforward swap for most home builders.
Can I use optics with the adjustable cheek piece?
Yes, that's one of the main reasons to grab this stock. The polymer cheek piece raises up to give you a proper cheek weld for red dots or magnified optics, and in its lowest setting it matches the factory height so you can still run iron sights.
Does the 870 stock hold extra shells?
The stock itself doesn't come with shell storage, but it has M-LOK slots on both sides. You can add the MI Universal Shell Holders to those slots if you want extra 12 gauge rounds close at hand.
How does the length of pull compare to the factory stock?
Out of the box it maintains the same factory length of pull, so it should feel familiar right away. If you need more reach, Midwest offers spacer plates as an add-on to lengthen it to your liking.
