May take some modification/fitting - Angstadt Arms 3-Lug Blast Can Muzzle Device

Bought this to use on a MPX with a ILWT 4.5" barrel. The black internal plunger piece that is inside the Blast Can would not fit over the outside diameter of the barrel. After measuring with calipers, it was about a .0015" difference. I took some sandpaper wrapped around a dowel rod and sanded the inside of the plunger until it fit. Since that exposed the steel, I used some $5 cold gun bluing to to recoat the plunger and prevent rust. Unfortunately not everyone manufactures tri lugs and barrel diameters to the same specs so some fitting may be required. Overall I'm still happy with the Blast can as it is a good substitute when not shooting suppressed.
