For cleaning the eyes you should have 2 removable plates on each side of the body (undearneath the feedneck left and right)
Use a small allen key and turn them out, under that you should have access to clean your eyes (pull them out carefully) and ball detents (black bit of rubber)
I dont have an SLG, but if its simalar to the PMR then you should be set..
Also as others have stated.
Make sure the bottle is screwed right in
if air leaks from the back of the bolt (area) then take the bolt out and make sure all the o-rings are seated correctly and add a nice amount of lube all over the moving parts of the bolt and o-rings.
After that you should be good to go. Hope it helps
