Description
Noveske took the flash hider and made it work overtime. The Pig Pen isn't just about taming muzzle flash, it doubles as a quick-detach suppressor mount built around the CAT 1×16 left-hand thread pattern that was recently made open source. That means if you're running a can designed for that mounting system, this flash hider gives you a solid, repeatable lockup without committing you to one brand's proprietary setup. This is the short version with 5/8×24 threads, sized for .308 and 7.62 NATO builds.
What Sets the Pig Pen Apart
The big draw here is versatility. The open-source CAT 1×16 LH QD standard means the Pig Pen plays nice with a growing list of suppressors from different makers, including cans from CGS, Cobalt Kinetics, and CAT's own lineup. For folks who don't want to be locked into a single ecosystem, that flexibility is a real selling point. On its own, it runs as a capable flash hider, and when it's time to mount a can, you're already set up.
Materials and Build on the Short Pig Pen
Noveske machines the Pig Pen from 4140 QT steel and finishes it in Black Nitride, so it holds up to heat and keeps its looks over a lot of rounds. The short configuration measures 1.93 inches long and weighs in around 2.4 ounces, keeping things compact and light on the end of your barrel. It ships with timing shims so you can index it correctly during installation. Everything is made in the U.S.A. with domestically sourced materials, which is right in line with what you'd expect from a company that calls itself the All-American Badass Rifle Company.
If you want the longer version that can be pinned and welded to a 14.5-inch barrel for a 16-inch overall length, Noveske offers that too, but this short model is the pick when you want the most compact footprint possible.

Frequently Asked Questions
What suppressors will the Noveske Pig Pen work with?
The Pig Pen is built around the CAT 1×16 left-hand thread QD pattern, which CAT made open source. That means it works with any suppressor using that mounting system, including cans from CGS, Cobalt Kinetics, and CAT itself. Always confirm your specific suppressor uses the 1×16 LH QD standard before mounting.
What's the difference between the short and long Pig Pen?
The short version measures 1.93 inches and weighs about 2.4 ounces for the most compact setup, while the long version comes in at 2.20 inches. The long one is designed so it can be pinned and welded onto a 14.5-inch barrel to reach a 16-inch overall length. This listing is for the short 5/8×24 configuration.
What thread pitch and caliber is this Pig Pen made for?
This model has 5/8×24 threads, which is the common pitch for .308 and 7.62 NATO rifles. Noveske also offers the Pig Pen in 1/2×28 for 5.56 and .223 builds. Make sure your barrel's thread pitch matches before ordering.
Does the Pig Pen come with shims for timing?
Yes, the short Pig Pen ships with timing shims so you can index the flash hider properly during installation. Shims let you dial in the clocking without relying solely on a crush washer. Standard muzzle device torque and thread prep practices apply.
