I'll add my experience and thought process with the 12.5" Grendel pistol I built.
I tried my 2.5-10x Vortex Viper HSLR on it. I found that given the limited mounting area on an upper receiver, the position of the ocular with the 3" or so of eye relief afforded by it was such that when I held it in a position that enabled me to resolve a target through the scope, the pistol brace was positioned in such a way that it could be perceived that I designed and built the pistol to be shouldered (even though it was not). If I was brought to court over the pistol and was asked to resolve a target via demonstration to a judge and/or jury, I was uncomfortable taking the risk that they could perceive that I intended for the brace to be shouldered (given its position). Given the "spirit of the law" regulating SBRs, that perceived risk outweighed the benefits from having the pistol and I ended up selling the barrel.
