A new barrel if possible for airball or reducing volume.
J&J made Sl-68 2 barrels but they are hard to come by .
Palmers will make custom ones at a price.
very good valve
After market upgrades rare now.
Here is my review of the Sl-68 2:
< First impression >
The sl-682 is a very cool looking marker, and has that neat little window on the side for cleaning and seeing if balls are feeding. On picking it up you know you are not handling a toy from its solid steel construction.
< Ball Feeding >
The sl-68 comes with a stock adjustable feed neck that is offset for people who like to sight down the barrel. It is a bit to big for 10 round tubes if you play stock class, but I find if you wrap some tape around your 10 rounds they can fit snugly without having to buy or build a stock class feeder. For hopper users no problem will be encountered.
The bolt is known to chop if you short pump it and this is where the side window comes in handy, letting you put a cord squeegee directly though the barrel. It also comes in handy for seeing if a ball is being fed to know if there is a hopper jam as I said before.
< Disassembly >
The Sl-68 2 is disassembled by loosening the front screw and taking the barrel out to get access to the bolt assembly (which can be slid out with the pump arm) and valve.
The barrel can be very difficult to remove and put back in as there are no threads, if this is a problem you should consider polishing the breach to remove debris and excess paint that may be causing this problem.
< Shooting the Marker >
When I brought it to the chrono with recreational paint I got +- 8 and a 5 bps with auto-trigger.
On shooting it I found the iron sight very useful and accurate, I could get a ball on top of ball at 50 feet and hit small targets such as beer bottles and hoppers in one shot easily when using the iron sight.
< In Game>
The Sl-68 2 is Light and maneuverable with its low profile, much like a Breach shotgun which is an essential in every close quarters operation with S.W.A.T teams world wide.
This Marker isnít awkward to carry and does not make you sacrifice stealth and speed. Though, it is a bit on the loud side compared to some markers.
In game a player attempted to bunker me, but I swung around and auto-triggered a rope of paint one on top of the other onto the top of his head. Shoot down is not a factor with this marker even at its highest (5-6 bps) rates of fire.
One problem I had with it was paint to barrel match. Being a closed bolt marker, if the paint is not a good size for the barrel when you pump it the paint will roll out or down the barrel reducing accuracy and range. Two ways to avoid this are to buy paint sized well with the markers barrel, or only pump the marker when you are ready to shoot.
< Operation >
Chops occurred mostly on auto-triggering the marker, as short pumping it was more likely when doing this, in which case the side window for cord squeegees came in useful for cleaning the marker, which did not shoot through breaks well if at all.
The marker had an anti double feed which is good for the person who may pump the marker run for five minutes and see someone and pump it again and double feed.
Double feeding was only possible with an electronic loader or pumping it, pushing the ball forward and letting another ball fall into place.
In playing is used this double feed method as a strategy to shoot two balls at once, surprisingly this worked 70% of the time to successfully propel two balls (with half the rang) but at 30 feet I got both balls to hit my friends scuba tank (one half a foot above the other) and also used it in game to double tag close quarters opposition.
Also with a co2 tank I aimed the marker at the ground and dry fired 200 times tiny to get just one drop of siphon ( and it was a non anti siphon tank) but it did little more than smoke. These markers take liquid co2 and chew it up and spit it out like its nothing.
< Durability and Build >
When Tippmann designed this gun, they built it to last, mine must be over 10 years old, more like 15. These markers could be run over by a truck, dropped out of an airplane, and thrown at a brick wall. The only thing they will need replaced in their lifetime under normal circumstances are O-rings. The only plastic thing on it is the pump handle, which is high impact all weather plastic and has not even shattered on me in the hardest winter playing conditions. And in the unlikely event it does a new one can be purchased from Tippmann (even now in 2006).
If you want to get into pump and can not afford a high end pump, the Sl-682 is your answer. If it is not a high end pump it is defiantly a high performance.
It may not be as upgradeable or accurate as my Wgp Sniper, but I would take and Sl-68 2 over it stock any day for solid performance and auto trigger ability.
The Sl-68 is indestructible and if you canít conquer your opponents with it you can always use it as a steel club to cast them down into the land of the dead (not recommended).
Accuracy: Stock is sufficient.
Efficiency: High, play all day off of a 9 ounce.
Durability: May be the most durable marker available
Feel: Low profile and easy to hold
I give it a 9.5/10 since I paid $86 Canadian for mine, and it was worth every penny.
The only weakness is it is not very upgradeable, which is not a factor because the stock parts are all you will ever need (unless you want to push air bunkers wit ha longer barrel) if it wasnít for this I would give it a ten, but since I can mark 9.5 I will round up to 10 anyway.
10 out of 10
