To use the Maple Leaf rubber you will likely need a new barrel, with an open cut like a pistol. The larger bump of the rubber does not fit in the hop-up window on the stock barrel. You could also file the barrel to enlarge the hop-up window. It's a great rubber, lifts heavy BBs easily and is very consistent once broken in (a few hundred shots). It's also one of the most affordable hop rubber out there.

The nine ball rubber works great, not the most accurate but it lifts heavy BBs easily. It doesn't like the cold though, and will likely get thorn by cylinder heads with larger nozzles or sharp edges.

As stated, the PDI rubber is great, but you will need an upgraded hop-up arm like I listed before to lift heavy BBs. You could also just fill the area between the two "arms" on the stock hop-up lever to get the same result. The PDI rubber has a poor air seal though, so it is possible that it would not work well without some tweaking in your setup.


As for paying so much for the base TM gun, its for a durable and quality platform that will accept high-end upgrade parts without requiring any fitting. You are much better off starting off a TM VSR10 and lightly upgrade it than get a cheapo clone and pay through the roof to upgrade it, spending hours fixing and fitting it to get a platform that will more than likely not shoot any better than a lightly upgraded TM VSR10.
