Thank you GeeRam and Seaforth., I thought that was likely to be the case. The only reason I could see is if one where going to regularly fire it directly from it’s chest.
And to you point GeeRam, I am lucky enough to have an all be it small strong room, so yes those that have a chest live in their chests. Also I like the look of them so I transport my L42 to and from the range in his chest.
