Hybrid Muzzle Brake & Compensator for Better Control
The Strike Industries JComp Gen 2 is designed as a hybrid brake/comp, combining the benefits of both:
Muzzle brake ports help redirect gases to reduce rearward recoil, keeping the rifle from pushing straight back into your shoulder.
Top and angled side ports are tuned to minimize muzzle rise, keeping your sights flatter between shots.
The result is a rifle that feels smoother, quicker, and easier to control during rapid strings of fire.
Whether you’re double-tapping on the range, running drills, or shooting in competition, the JComp Gen 2 helps keep your dot or crosshairs where they need to be.
Designed for 5.56 / .223 AR-Platform Rifles
This specific JComp Gen 2 variant, JCOMP2223, is optimized for:
5.56x45mm NATO / .223 Remington
AR-15 barrels threaded 1/2"-28 TPI
Standard AR-15/M4 carbines, pistols, and SBRs that can accept a 2.55" muzzle device
It’s a direct replacement for any standard 1/2"-28 muzzle device, making it a simple, drop-in upgrade for most AR-15 platforms.
Compact 2.55" Length – Agile and Handy
At 2.55 inches overall length and roughly 0.87" in diameter, the JComp Gen 2 is compact enough to keep your rifle:
Maneuverable in close quarters, vehicles, and around barricades
Compatible with most free-float handguard setups without excessive overhang
Visually balanced with 16" carbines and shorter barrels alike
It gives you performance without turning the end of your rifle into a massive, unwieldy brick.
Classic J-Comp Inspired Styling with Modern Refinements
Strike Industries built the JComp Gen 2 as an evolution of the popular original JComp, inspired by classic Japanese compensator designs:
Aggressive, multi-port face that looks as good as it performs
Clean, machined flats and flutes for a modern, tactical aesthetic
Compact profile that flows naturally with today’s slim free-float handguards
It’s a functional upgrade that also adds a distinct, custom look to your AR build.
Black Steel Construction for Durability
The JComp Gen 2 is built from strong, heat-resistant steel, then finished in black for corrosion resistance and low glare:
Steel construction stands up to sustained fire and high barrel temperatures
Black finish matches most AR receivers and handguards for a cohesive appearance
Designed to withstand regular range trips, classes, and high-volume shooting
If you’re hard on your gear, this is a muzzle device that’s ready to keep up.
Better Performance Than a Standard A2 Flash Hider
Compared to a basic A2 birdcage, the JComp Gen 2 offers noticeable benefits:
More effective recoil and muzzle rise reduction, especially during rapid fire
More defined gas redirection, contributing to faster sight recovery
A more “locked-in” feel when shooting from standing, kneeling, or offhand positions
While the JComp Gen 2 is not a dedicated flash hider, it’s designed for shooters who value control and speed above all else.
Simple Installation on 1/2"-28 AR Barrels
Installation is straightforward for anyone familiar with AR builds:
Ensure your rifle is unloaded and safe.
Remove your existing muzzle device from the 1/2"-28 threaded barrel.
Install the Strike Industries JComp Gen 2 using an appropriate crush washer or shim set (typically not included; follow Strike’s instructions).
Torque and time the device as directed so that the ports align correctly.
After installation, verify that the bore is clear and concentric before live fire. If you’re uncertain, have a competent armorer or gunsmith install it.
Ideal for Range, Training, and Competition Builds
The Strike Industries JComp Gen 2 is an excellent choice for:
General-purpose AR-15 builds where recoil control is a priority
Competition rifles in 3-Gun, USPSA, or local matches
Training carbines used in high-round-count classes
Personal defense and home-defense ARs where faster follow-up shots matter
If your goal is a rifle that shoots flatter, tracks better, and feels more controllable, this muzzle device is a smart upgrade.
