Magpul SGA 870

Magpul SGA 870 Stock — More Than Just a Shotgun Upgrade

If you’re still running the factory furniture on your Remington 870, it’s time to evolve, my dude. The Magpul SGA Stock isn’t just a comfort upgrade — it’s a game-changer. Whether you’re defending your home, your land, or just want your boomstick to look and feel like it wasn’t issued during Desert Storm, the SGA delivers.

This ain’t your grandpappy’s walnut stock. This thing is modular, rugged, and made to run — not just on shotguns, but also on ranch rifles like the Foxtrot Mike, BRN-180, and other bufferless AR platforms. Yeah, you read that right. Let’s break it down.

Why the SGA?

The OEM stock on your Remington 870 is fine… if you’re into slippery cheek welds, fixed length of pull, and zero modularity. The SGA Stock, on the other hand, is made for modern shooters who actually train with their gear.

Magpul didn’t just slap a tacticool label on this — they designed it from the ground up with real-world use in mind. Whether it’s a red dot-ready fighting shotgun or a minimalist, side-charging ranch rifle, the SGA adapts.

Features That Actually Matter

1. Adjustable Length of Pull

No tools, no drama. Add or remove spacers to adjust the LOP from 12.5" to 14.5". Whether you’re running slick, loaded with gear, or just have monkey arms — this stock adjusts to fit you. Perfect for high-speed or high-fatigue environments.

2. Built-in Sling Mounts

Integrated ambidextrous sling points are molded in, so you're not zip-tying hardware like a broke DIY YouTuber. Single-point, two-point — run whatever setup makes sense for your mission.

3. Cheek Riser Compatibility

Running ghost rings? Red dot? LPVO on your shotgun or ranch rifle? Throw on a cheek riser to match your optic height. Magpul makes risers in multiple heights, and they pop on without tools.

Wait… This Isn’t Just for Shotguns?

Exactly. While it was made for the Remington 870, smart builders and freedom nerds have started adapting this stock onto other platforms — especially bufferless AR builds.

You’ll find this stock on:

• Foxtrot Mike FM-15 Ranch Rifles
  
  

• Brownells BRN-180 builds
  
  

• AR pistols using MCX-style buffer adapters
  
  

• Custom bolt-action and lever gun projects
  
  

All it takes is the right adapter or receiver extension (and yes, those exist), and boom — you’ve got an ultra-compact, ultra-rugged stock made for real use, with shotgun-tough ergonomics.

This means the SGA is doing double-duty: it’s a beast on your pump gun and a smart pick for side-charging or folding-stock builds where you don’t want an AR buffer tube setup. And let’s be real — it looks mean in that minimalist polymer form.

Durability and Recoil Control

The SGA isn’t just pretty — it’s built like a tank. It’s molded from high-strength polymer that laughs at moisture, impact, and truck beds. The built-in recoil pad is thick enough to eat up punishment, especially when you’re blasting 3” slugs or hot 5.56 from a lightweight build.

Combined with the improved grip angle (more vertical than traditional hunting stocks), the SGA offers more control and less fatigue. This especially matters when you’re running fast drills or awkward positions — like clearing corners in your hallway or chasing coyotes off your land at 2 a.m.

Installation: Quick and Painless

If you can field strip your shotgun, you can install this stock. Remove the old one, bolt this one in, and you’re done. No permanent mods required. If you’re using it on a different platform (like the BRN-180), you'll need an adapter, but even then it's still stupid easy compared to some other stock swaps.

Who Should Run It?

You should — if you fall into any of these:

• Home defense shotgun user
  
  

• Ranch rifle or truck gun builder
  
  

• Minimalist AR tinkerers
  
  

• Competitive shotgun shooters
  
  

• Anyone who’s sick of old-school ergonomics and recoil slap
  
  

This stock is for shooters who care about fit, function, and modularity, not just looks.

Final Verdict: Worth Every Penny

The Magpul SGA Stock takes your old 870 or your side-charging AR platform and gives it a modern soul. It’s affordable, rugged, and adapts to almost any setup with minimal work. Plus, it’s backed by the Magpul name — which means it’s made for abuse, not babying.

If you want your setup to feel like it was built for you instead of for the shelf, this stock is the move.
