Without going into detail as to how I came to be in this situation (very short story - oversight on my part), I find myself in need of a 2 piece gas block. I have a 14.5" barrel with a pinned and welded muzzle device. It's a carbine length 308 and will occasionally host a silencer. I'm not opposed to an adjustable gas block. In a quick search, I found a couple, one by JP Enterprises, one by Witt Machine & Tool, and one by Paper City Firearms. Does anyone have any experience with any of these or any other recommendations?
