UK Neil made this for me a while back, don't use it as was an experiment for my benchrest RT and it shoots best with no shroud or anything else.
The shroud is fully free floating being slightly less diameter than the original and attaches to the barrel at the rear where the slightly thicker piece can be seen. Air cone section also thin enough to free float in Daystate figure of 8 the reason the rest is so thin is it originally was made with a balance weight for harmonics which I have removed as I realised my design was flawed.
Looks great when fitted. Might put it on a HFT setup.
Rick Ardern super low mounts ISP MK3 pellet launching platforms and Sightron 10 x 42mm telescopic sights.
Because it is not about how, but how many.
