First off I have been told (on the internet) and understand all of the above are unnecessary on a civilian semi-auto pistol caliber carbine.
But they look so cool I want one for cosmetic purposes only.
Also been told (on the internet) they can make the rifle louder? (Not what I expected

).
And been told (yes, on the internet)
some can actually make your rifle less accurate (deal breaker for me).
Yes, I get the irony that I am asking on the internet to confirm/ deny what I heard
on the internet.
But I know and trust you guys plus many of you are very accomplished/experienced at building your own spoons and I presume you know much about such things.
{This is my first long gun other than a shot spoon}
Thanks much
