Questions & Answers
The full size Ruger PC Carbine is not one of the listed platforms. Am I correct to assume that this will perform also work on the Ruger PCC (1/2x28)? Manufacturer Answer

The NERO 9 should work on the Ruger PC Carbine in 9mm just fine. It comes with a fresh crush washer and as long as that Ruger PC Carbine is threaded 1/2x28 you should be good to go.

How effective would this be on a 350 Legend? Expert Answer

The Walker Defense Research Nero Compensator NERO9 might work on a 350 Legend if the barrel is threaded for 1/2x28. However, I recommend contacting Walker Defense Research to confirm that the Nero9 compensator can be used with 350 Legend due to the pressure differences in the two cartridges.

NERO 9 is amazing! by David Lightfoot, Verified Owner, June 27, 2025
This is worth every penny I paid for it and will be buying one for my 5.56 and 7.62 rifles as well. Installed on my Smith & Wesson FPC 9mm and instantly feel the difference in recoil and muzzle movement. Follow up shots are so much faster! Buy it…y...

Works Well-Looks Good by Archer, Verified Owner, March 15, 2025
I installed this on an LWRC IC-9 which arguably has minimal recoil and muzzle rise. Like so many I like personalizing my weapons and improving performance. The comp comes with one crush washer and nothing else. Instead of the crush washer I opted for...

BEST 9mm carbine comp on the market. period. by Justin, March 20, 2021
No, it’s not cheap. But in my opinion, I will not waste my money buying something that does not perform as well as another product just to save a few bucks. If you are looking for the absolute cutting edge in innovation and performance, look no furth...

Beyond Expectations by 9mmfan, February 11, 2022
I have tried a wide assortment of compensators for 9mm and this is the first one that does what it says it is going to do. It may not be the most attractive unit out there (I like the ray-gun look!) but form follows function and it does a terrific j...

Perhaps worth the cost by birdman, Verified Owner, January 8, 2022
Helps with up/down force and recoil. Barrel stays steady, easily allows next shot. Looks great, no bad-a$$ actually. 4 stars because it won't stay in position without pinning on my Rugar Charger 9mm anyway. Yes I used the crush washer and perhaps wit...

Product Info for Walker Defense Research Nero Compensator

The Walker Defense Research (WDR) NERO 9 compensator is purpose-built to handle the notable muzzle rise of pistol caliber carbines (PCC) with a blowback action. Whether on a PCC or a submachine gun, the NERO 9 maximizes what a compensator can do with the limited pressure of 9mm and is designed to keep the muzzle as flat as possible, shot after shot. Additionally, the NERO 9 has negligible lateral concussion, making it a viable option for tactical applications.image

WDR designed the NERO 9 to raise the bar for what is expected of a PCC muzzle device and leveraged cutting edge technology to make this happen. WDR rejected all design constraints and engineered the NERO 9 using computational fluid dynamics (CFD). The unorthodox shape was so complex it could only be manufactured by leveraging an exotic form of additive manufacturing called direct metal laser sintering, or "DMLS". The NERO is made from Inconel, a nickel-chromium superalloy used frequently in aerospace for extreme environments, and especially in high-heat applications.
