I have a nice FH from arsenal. I got it for my sam7k but I just rigged it to qd my can. No longer needed. It works extremely well and eliminates damn near all muzzle flash. I shot it at night and didn’t see any red/yellow light coming from the barrel. Will take trades for surefire,modlite,cloud,Ak pmags, red dots, or greenbacks. I can ship for $10. Works with 7.62x39 and smaller
