Whoever thinks of this teflon tape and barrel spacer nonsense sucks. Here is what I have always done, and I have no idea why nobody ever did it before.
Take the cylinder out of the gun. This is done by pulling the spring guide stopper located up under where the trigger hangs from. It takes a little strength but it will budge. Once you have it out remove the cylinder head, I have no idea with the clone ones if they come off or not, but you need it to open.
What you are modifying is the tension on the spring. You need to make A tensioner spacer. I have always cut sections out of steel Wolf AK47 bullet casings, but any piece that fits around your spring guide will work, that the spring can sit on. You need to make sure it is not too long, otherwise you will not be able to pull your cylinder all the way back. I don't have any pictures of mine, but they look similar to these www.trinityairsoft.com/p-339-vsr-spring-tensioner-6pc-set-by-laylax.aspx
If your still having trouble understanding what I'm talking about, you need to keep the gun the way it is otherwise you will end up breaking things.
This modification is good up to about 50-60fps, enough to stress the stock China plastic trigger housing. Like it needs any more with "450fps" out of the box.

No problem bud, I myself have been using this guide as well. I know that there are a lot of people that will discredit and say every bad thing they can about the UTG MK96 but this goes to show that you can make it perform greatly without breaking the bank. sure its not a Maruzen but it can still serve the owner well.
Even though your sears look fine, the plastic housing around the sear pin will break with modifications. My Maruzen's held at 500fps for about A year, with around two years of being stock before that. I would suggest A King Arms Lightweight Trigger Unit, mine has held up very well for A long time.
Here is where it breaks.
I aim I squeeze, Pause for a moment a passing breeze. My finger steady, my trigger cold, I feel the recoil and watch him fold.
The teflon tape around the cylinder head is only good for about a mag worth, so in other words... Not really worth it to begin with. As far as free/inexpensive upgrades go. There really isn't just that one magic thing you can do to your rifle to make it better. Because by upgrading the spring you need to upgrade the trigger housing (As Livonia posted). Upgrading anything else other than throwing a tightbore in the weapon really won't make much of a difference (I.E. Cylinder Heads, only buying a trigger housing, reinforced bolt, or even a different cylinder set). Remember, you get your accuracy from your barrel and your consistancy from the hop up. Anyone who says more fps = more accuracy & consistancy is a fool. I used to have the newton's law of physics on the actual weight of bb's and different FPS's that it shot at.
Also, I reccomend heavier bb's. If you're not already shooting at least .28's, then go for that.

Thanks for the responses guys.
I'm shooting Madbull precision .36s. They work beautiful.
No true, FPS DEFIANTLY doesn't mean accuracy, it COULD mean range.
I ended up doing a few mods, Teflon tape on the barrel, cylinder head. Put some silicone oil on moving parts, trigger group, bolt, ect.
The mod i saw the most accuracy out of was taking a rubber hose from a my cars stock intake about a inch thick? I guess, and some electrical tape and making the all fit snugly into the barrel, so there is not movement or vibration. As soon as I shot it, I was like "this is it" it made the gun very consistent, even when I was not trying hard to hold it steady, no more free flys, right or left. All into a 10 inch by 10 inch target at about 150ft.
My stock is also filled with foam, i took it apart in two pieces and fitted everything. If you knock on the stock anywhere it doesn't sounds hollow, or cheap.
Filling in the hollow parts of the stock with foam sound like a pretty good mod. I might try doing that. And barrel spacers do increase consitcy so I might do that as well with different materials but with the same outcome. But I just posted a review on a upgrade made for well/utg rifles you may want to check that out. It isn't free but it is cheap at only $35. I'm going to be using my rifle for the season until after october when i'm going to upgrade to a better platform.
