I have a Bushy M-4gery with the mini Y comp. The blast you feel when you pull the trigger is great AND loud. In fact, I wear soft ear plugs UNDER a set of regular muffs.
I agree its brutal, I will not buy another rifle with one BUT I certainly will not remove mine or re-bbl the rifle to get rid of it.
The only down fall is if I ever need a rifle for a SHTF situation, I better not grab it (hell I have plenty of others) because it will seriously screw up your hearing as I did some experminting to see just what I could and could not do in an emegrency.
I figure it this way, my dad once put glass packs on the family van when I was a kid, when asked why, he replied "because gas costs so much now (gas crunch late 70's)...I want to hear it when I burn it". Thats how I feel about ammo costs etc...I want to hear AND feel it.
