AR-15 – Compensator – 1/2x28 – JCOMP Gen2 – .223/5.56
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The Strike Industries JCOMP Gen2 is a Type 89-inspired hybrid muzzle brake / compensator built for shooters who want stronger recoil control and better muzzle rise reduction without going full obnoxious science experiment on the end of the barrel. Strike Industries kept the original concept, then updated it with a two-chamber design and SI OPPRESSOR compatibility for modern AR builds.
This .223/5.56 version is black, threaded 1/2x28, and built for .223 Remington / 5.56 NATO hosts. It is a clean fit for AR-15 rifles and carbines using the correct thread pitch and caliber.
Fitment
- Fits .223 Remington / 5.56 NATO barrels threaded 1/2x28
- Strong fit for AR-15 rifles and carbines with standard 1/2x28 muzzle threads
- Compatible with the Strike Industries SI OPPRESSOR
Does NOT fit
- Barrels with thread pitches other than 1/2x28
- Wrong caliber applications
- Shooters wanting a flash hider instead of a compensator / brake hybrid
What it does
The JCOMP Gen2 uses a two-chamber design to improve recoil management and muzzle rise control while still functioning like a combo muzzle device. It gives the rifle a more stable feel under rapid fire and follow-up shots.
Why it’s worth it
This is one of those parts that makes sense because it actually does a job well and doesn’t pretend to be sacred relic technology. Good control, known fitment, and solid price-to-performance for AR shooters who want more than a plain thread protector.

Install notes
Proper timing matters. Use the included crush washer, verify thread pitch before install, and make sure the selected muzzle device actually matches the caliber and barrel setup instead of just “looking close enough.”
Verify before you buy
Verify the barrel is .223/5.56 and threaded 1/2x28 before purchase. This is not the .308 version and not a universal-fit muzzle device.
