The Valkyre deslisle is pretty much awesome looking. Faithfully executed for sure. A real collectors item. I don't really agree that the baffle system is "maxim". I think the inventor was the first to use the rods and bent split washers to assemble the baffle system, and it works great for sound, but the history I read didn't suggest the best accuracy in military trials. I read an article somewhere where the accuracy results were surprisingly bad.
http://www.scribd.com/doc/41365896/Deat ... ng-DeLisle This mentions the issue, but doesn't go into detail. I shot an L34A1 and it was having poor accuracy also and used the Deslisle style split washers. I had the front sight maxed out for elevation on that gun, and some of the rounds were flying erratic of the rest. I think the silencer could have been slightly miss aligned, but wonder if the baffling was just a poor design for accurate work.
The unit we have is SIA, and it probably isn't as quiet, but it is accurate- shooting ~1.5MOA. We were kind of wanting to be picky with sound even though the sound was like a hammer on steel and not like a gunshot, it was loud. We laser cut a bunch of diffusers that look like cookie stamping dies for those cookie caulk guns. Assembled into a stack, with the baffles up front, the silencer sounded better. I didn't meter it, but it still shot 1.5MOA, and sounds better now. Maybe we'll meter it next time I'm home. I'm sure that's not the best way to baffle it either but the M baffles and spacers that came with the suppressor are pretty far apart and that lets some gas blow by creating that sharp 135DB average. The lasered sheet metal diffusers were just more cost/time effective than seriously getting involved in baffle design for one silencer.
As far as Red jacket, I was talking about their poor shooting for people who work around guns. The show is entertaining, I enjoyed watching it and it probably increases NFA awareness, but where they really got me was the episode where the owner's gunsmith on NATIONAL TELEVISION, tells the owner he needs a depth micrometer to properly headspace a barrel (a big safety issue) and the owner tells him if he can't do it with the tools he has there he needs to pack his things. <really? I have depth mic. I can't say I often use it, but I did QC check some checkmate QD mounts with it a couple weeks ago and it came in handy. If I were the owner, my answer on television would be, "alright well make it happen." I'm sure there are ways to work around not having the appropriate tool (like maybe using shim stock and a round of something like that to check headspace), but TV isn't the right place to be talking about how to work around not having the right tool for a job. I wouldn't want people without the right tools headspacing a gun for me, so why do it for someone else?
