AR-15 – RA-701 Compensator – .223/5.56 1/2x28 – Black Nitride
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The Rise Armament RA-701 is a .22 caliber compensator for .223 Remington / 5.56 NATO rifles using 1/2x28 muzzle threads. It is built to help flatten the rifle during firing by reducing recoil impulse and muzzle rise, and the versions here are offered in Black Nitride and TiN Gold.
This is the kind of part that makes sense when you want a rifle to track flatter and return to target faster without turning the muzzle into a boat anchor. Just verify thread pattern, caliber use, and your muzzle device clearance before ordering. The rifle will not magically become John Wick because you threaded on shiny metal. But it will behave better if the setup makes sense.
Available options are organized below under Variants.
Fitment
- Fits .223 Remington / 5.56 NATO barrels with 1/2x28 threads
- Works on AR-15 pattern rifles and similar rifles using the same thread pattern and caliber class
Does NOT fit
- .30 caliber barrels using 5/8x24 threads
- Barrels with non-1/2x28 muzzle threading
- Setups where handguard, suppressor mount, or other accessories create clearance issues
What it does
The RA-701 redirects gas to help control recoil and muzzle rise. That means less climb, faster sight recovery, and better control during quick strings or transitions.
Why it’s worth it
If you want a practical muzzle device upgrade instead of a decorative barrel ornament, this makes sense. It is compact enough to stay usable on real rifles, and the price still leaves room in the budget for ammo — which is good, because the rifle still needs a man behind it.

Tools needed
Appropriate armorer tools for muzzle device installation. Shim/crush washer needs depend on your setup and are not assumed here unless specifically included by the manufacturer.
Install notes
Install like a real muzzle device, not like a caveman with a crescent wrench. Confirm thread engagement, timing, and bore alignment before firing.
Verify before you buy
Verify barrel thread pattern is 1/2x28 and verify you are shopping for a .223/5.56 device, not a .30 cal model. Also confirm any suppressor-adjacent or handguard clearance needs before ordering.
