Maruzen rifles ---> Maruzen hop up and disassembly guide. Should have 99% of what you want to know.

On the other hand, with any stock rifle you're going to have to get down and dirty for good performance. At the very least you'll need to degrease everything, clean the barrel, and shim or tweak the hop up in some other way.

Just a tidbit on the build quality

The nubbing (nub) is the buffer between the hop up arm and the rubber. SCS (shredder's concave spacer) is a good one. You can also mod your own concave nub.

Generally in the L96 a concave nub is the way to go as opposed to a cylindrical or H-nub. The PDI chamber's design isn't perfect but doesn't have as much room for modification as a vsr-10's (although you can do a decent amount) so a flat top-down adjuster isn't a great idea.
