I need to reiterate that I posted this for input only......We are not using an off the shelf AR barrel.
Well if you want input, I think you should not be so dogmatic about having a custom contoured Shilen barrel and listen to what people who point rifles at other people for a living are telling you is important.
Sorry I pissed you off. That certainly wasn't my intent. At the advice of you and others, the barrel will be 16" and contoured for lighter weight. Just because I want a Shilen barrel doesn't mean that it will be short and heavy. What is a lighter butt stock that we can find? We are changing to another trigger also.
Bluedreaux, PM an email address and I will send photos and so forth about the gas block so you can give your opinion about it.
Like most of you I do have an ego, but I will not let it get in the way of this build.
