Those look nice!. I knew about that option, and I did the same "trick" with a Ruger 10/22 where I permanently pined/soldered a barrel extension that goes over the smaller Form 1 22cal suppressor. In fact, it was the commercial version that gave me the idea about the "long" barrel muzzle brake.
That customized 10/22 was the first rifle my daughter shot with a suppressor, and it is the rifle my daughter tells me its 'her' rifle. I could not and did not wanted to argue that one, so I simply bought parts and made another 10/22 rifle instead
