So I finally joined the pcp club and picked up a Brocock Specialist. Very happy with the purchase used (got a great deal on it) but I did notice that the shroud is rotated oddly such that a fluted section (where it would sit next to the air cylinder, I guess) is on the side. Long story short I'd like to loosen the end piece and rotate the shroud back into position. Only problem is it's on there like the dickens. Any idea why this would be the case and how I could unscrew it without damaging it?
