A quick test last night showed that I was shooting about 7mm to the right and very slightly up. Now it could easily have been ok on the Sunday and I was just rubbish that day, it happens. But maybe I should have checked a bit more on the pre comp plink? Another lesson learned.

But are you saying that there needs to be clearance between the stock and the cylinder as this can cause the POI to move?

Also I might want to go down the route of taking off the current barrel shrouds and float the barrel. If I do can I ask two questions,

1, Doesn't fitting the 'O' rings then connect the new carbon shroud to the barrel again?

2. Where would be the best place to get a carbon shroud/tube IYO?


Bought one from easy components,1 meter, slight pitting at one end(dust got in wrap) could do deal? with unused section.If barrel sorted on 900 again,I might use clean end,maybe!

Default Barrel not blued

Under the front stripper locating grub screw hole, below the barrel there are two holes like the locators that screws fix the breech end of barrel with.
Question is: for those who have removed the bits and pieces. Does the blueing on yours compare to that on the 400,510's or is a bit tatty;and do they have the locating holes on both ends of barrel.
I have lots of time to sort this out while ankle mends itself,but would like your input,Vinces too if he's on forum.

This is only my opinion but I believe the reason why we see shrouded guns is that blueing a barrel has to be done carefully ensuring that the inside of the barrel doesn't get blued as this has a negative effect on accuracy. So the easiest answer for manufacturers is not bluing the barrel and fitting a shroud, hence your barrel will be rusted.

When barrels are hot blued the barrel ends are plugged to stop fluid ingress, the transfer port is left open as the hot process may distort the barrel.

Any other views?

The FTP barrel is blued, the shroud is there just to make it look pretty.
