Love it on 5.56, but causes malfunctions on 5.7 - SureFire Warden Blast Regulator

Weird one. Works as advertised. Fit is just as good as a suppressor. No movement or rattle. Does a good job essentially as a QD linear compensator. This is all on 5.56 ARs. I tried it on my 5.7 Banshee and after months of issues with the rifle, different triggers, buffers, lubricants, and ammo, I took off the Warden and the gun functioned 100%. This rifle also had issues running suppressed, but was really surprised how sensitive it was to a linear comp. Overall, I do recommend. I love it on my SBR SCARs and ARs when I don’t feel like dirtying up my guns by shooting suppressed.
