Just for trying something different than the big Moderator In my. 22 uragan I have a old .22 sumo with the small hole.. sound pitch was a bit high but usable..i try the .25 sumo a bit higher pitch..I had Donny 2 FX moderator around so I ordered a custom End cap in AGT treads from Donny.. AWESOME fast service.. to my surprise the Fx moderator is the most quiet of all .. tried on the .25 same results..even quieter than the shogun.. tried on the .30 uragan same result..now I not only enjoy a more quiet gun ..is a shorter maneuverable gun.. all are tuned in high power.. but to the .177 uragan the best moderator was a old .177-.22 tazu .. it has a smaller hole than the new ones..
