Finally got my donor barrel in (ordered it two weeks ago) I took a 16” Indy Ord barrel, cut it down, crowned it, threaded it, and installed a SiCo 3 lug adapter. I set it as close as I could to the shroud so there wouldn’t be a big gap, but just enough to install said suppressor onto it.
I’ll be trying this out tomorrow…I must admit I am giddy like a little kid waiting for Christmas morning….
