More than 5 years
Products Used:
Various spyders
Tippmann 98 and A-5
Smartparts ion
Marker Setup: SmartParts SP-1 with 16" J&J ceramic barrel,
Remote line running on compressed air.
Empire II sound activated hopper.
New barrel, and a remote line unless You are using a carbon fiber tank,
compressed air.
I would also recomend getting a stock.
Strengths: 1) Light.
2) Easy to disassemble and clean.
3) Fire rate.
4) Very quiet.
Weaknesses: 1) HARDLY WORKS WITH CO2.
2) Velocity adjustment.
3) Has a berrel shroud.
Review: When I first got the gun I was impressed with its weight and feel. The gun wasn't too heavy and the grip felt nice and sturdy. The stock barrel was very small, only 10" which is why I ordered a new one with the gun. I didn't like the fact that it doesn't come with any allen wrenches for disassembly.

The first time I fired The gun I used CO2 which didnt work at all. I thought it was primarily because it was about 30 Degrees outside. So I took The gun inside and let it warm up a bit and tried to dryfire it, and after about 10 shots the gun froze up again. The solonoid can't take the freezing effects from CO2 and simply freezes up after a few shots then you must thaw it out before you can fire it again. Also if You adjust the velocity too high the gun sprays air out of every nook and cranny. So I had to go out and buy a compressed air tank (72 cubic inch 3000psi) for the gun so it would work right. When I used it for the first time with compressed air it began to perform like I wanted it too, Unfortunately I only had one compressed air tank and that lasted me only about 600 rounds which I think was from my remote leaking. So I ended up using my spider VS1 for the rest of the day running it on CO2.

during the time i did use the gun it performed pretty well even know it was 35 degrees outside with snow. The compressed air did the trick but I'm going to have to buy another compressed air tank to use it all day because I don't have the option of refilling after every game when I'm in my friends woods.


Alright, I'm giving the gun a little more credit as I have used it more I have come to trust the gun a bit more. But I still say to give this gun time and don't just jump on buying it. Wait a few months (at least until it gets warmer out if you live in the north-eastern US) give companies time to release upgrades like the stock adaptor plate and double trigger kit that recently came out. I still think I would have preferred something like an
A-5 but This gun will have to do because I'm not ready to go out and buy another gun yet.


I just got my gun back from SmartParts after they did some repairs, (great customer service), and the gun seems to be working fine. I would recomend this gun to people just starting out at the sport of paintball or people looking to get a good gun at a low price. After I got the gun back It didnt delay between shots like it was doing before and I am getting a good fire rate out of it, thank you SmartParts
Conclusion: I would have to say don't buy this gun because there aren't enough upgrades for it yet, and unless you are only playing paintball in 90 degree temperatures you better have a good bit of extra money to buy compressed air tanks with because if the temperature is any lower than 90 the gun is just gonna freez up on you with CO2. Plus for 50 more bucks you can get an A-5 which runs fine on CO2 and has more upgrades than just about any gun on the market.

P.S. Yes I know that your not supposed to use CO2 in a Electro Pneumatic, But when Its all over the internet that you can, why use HPA?
Yes I also know that CO2 is bad bad in cold weather, but if it still works in all my other guns, why not this one?

"hardly works with co2"
your not supposed to use co2 in an electic gun

At 30 degrees, yes, even with a PPS stab, the stock reg and an anti-siphon setup (or remote) this marker will not work very well.

However, in warmer weather you can use it nearly trouble free on CO2. However, one thing you must do whenever you're planning on running an electro-pneumatic gun (one which uses a solenoid valve, like the Ion/SP1) on CO2 is get an ANTI-SIPHON kit installed for your asa/tank (although a remote will accomplish the same ends).

The goal here is not to let liquid CO2 into the gun's internals, especially the delicate solenoid valve, as they will literally kill the marker's seals. An anti-siphon setup, at least in principle, wouldn't allow an liquid CO2 to enter the marker. A remote setup would also accomplish the same ends, however you don't want to use a remote setup with an anti-siphon setup for more than one reason.

Anyways, the upshot is you can use CO2 with this sort of gun-just as long as it is warmer than 45 or so out there. I wouldn't, but that is because I have HPA readily available. If you don't have an anti-siphon setup on your CO2 tank/ASA then, as they're at most 15-20$, I strongly suggest you talk to a store tech or someone about getting it installed. It'll be great for nearly any gun you run CO2 on.

Yes, I know that, but when you dont have the extra money to spend on compressed air you have no choice.

I am disputing this review on the grounds that you failed to do your research.

1. The gun will run on CO2..however if you read SP's website they strongly suggest Anti-Siphon CO2. If you would have invested the $5.00 in an anti-siphon kit for your CO2 tank you probably wouldn't have had the problems and would not have spent that money on a compressed air tank. If you had done your research you would have known this.

2. As for upgrades...give it time. The gun has been out less than 3 months, there is no way it will have hundreds of upgrades like the A-5 does. However, there are many upgrades verified in the works including a new Blackheart Board, Double Trigger, Stocks, Barrel Kits, Qloader setups, and many others. Once again, if you had done your research you would have known this.

3. You complained about the gun not being very efficient...yet you say your remote line leaks. That is very contradictory. I ran my SP-1 with a 48/4500 tank and it lasted about half the day (keep in mind this was a scenario so I was shooting more paint then someone playing recball/woodsball).

his marker is probably the best marker for the price. Its fast, strong, and dependable. Before you buy something next time, research it.
