Why Modify a Remington 870 Barrel?

Shortening a Remington 870 barrel is one of the most practical and exciting modifications you can make. The process is straightforward:

1.  Take a factory 28-inch or 30-inch vent-rib barrel.

2.  Cut it down to 18.5 inches (or your preferred legal length).

3.  Ream and tap it for a Remington choke.

4.  Add a tactical front sight bead.

And just like that, you have a barrel that can truly do it all.

“I’ve used mine to shoot skeet (and win) in the morning, and (after changing chokes) shot slugs in the afternoon.”

Why Modify a Remington 870 Barrel?

Some might question whether a modified barrel can handle such a wide range of uses. The answer is a resounding yes. Thanks to removable chokes, this barrel can switch between loads seamlessly—from precision slug shots to spread patterns for ducks.

The Drawback of Tactical Barrels

Many tactical barrels lack removable chokes, limiting their use to specific loads like breaching rounds, slugs, or 00 buckshot. While they excel in these areas, they fall short when versatility is required, such as hunting waterfowl. This is where the modified Remington 870 barrel truly shines.

What About Length and Velocity Loss?

A common concern with shortening barrels is the potential loss of velocity. Here’s the good news: Most 12-gauge loads maintain their velocity until the barrel drops below 14 inches. Since legal lengths start at 18.5 inches, you’re not losing any critical performance. If you prefer a 20-inch barrel, that works too—it’s all about personal preference.

“A legal 18.5” barrel will retain all it needs to get the job done.”

Simplify Your Setup

One of the Remington 870’s biggest advantages is its easy barrel-swapping capability. But why maintain a collection of barrels when a single, modified one can meet all your needs? By cutting and modifying your factory barrel, you gain a multi-functional tool that’s ready for anything.

“Have that factory Remington 870 barrel cut and be done with it.”

If you’re looking for a reliable, versatile solution for your Remington 870, a shortened, reamed, and choke-threaded barrel is the way to go. Whether you’re defending your home, hunting in the woods, or hitting the skeet range, this barrel mod has you covered.
