The revolutionary Anti-Chop System is the world’s first true anti-chop bolt. Simple and affordable, the ACS bolt delivers the same results as expensive markers with eyes. Just replace your existing bolt with the ACS bolt…simple as that! The ACS precision spring tension recognizes obstructions before crushing balls and jamming the marker, so the action never stops.
The Kingman ACS Delrin Bolt is newer, so it should be commonly available, both new and used.
Does not prevent all chops
Chops even when ACS kicks in +more
Ok this bolt must have been the worst bolt ive ever used. It does chop paintballs, when it jams itself to prevent choping it still chops, it come uncocked for no reason sometimes, ive had it jam itself to prevent a chop on my first trigger pull and it still choped. This bolt also gets annoying because you have to keep recocking it constantly at high and low speeds. Although you can modify it to not have the ACS effect it really not that worth it and there are better bolts no matter what you do to it.
As soon as I bought the gun, I went out and purchased the acs bolt cause i knew i would be chopping balls. As soon as i started shooting fast, i was chopping balls about every 5 to 6 balls. The next time i went out, a piece of delrin broke off the back and jammed the trigger up.
I would not recomend this bolt because it does not do what it is supposed to and is very cheesy.
EDIT(new gun): Ion Max'd, Critical Parts Trigger, VLocity Jr, JT USA HPA Tank(not too great)
prevents SOME chops
When shootin fast, you'll most likely chop
Ok, this bolt is alright, still nothing close to eyes as soon as you start shooting over 10 bps chops will occur.
Even when you shootin slow, and your usin oldish balls / soft balls this thingll start to chop. I used this for one day, used about 1000 balls, and chopped like a good 10 balls, this thing isnt that great
Ok, it helps, but its not worth the money to buy, just get eyes

Makes chops less often
chops if you shoot more than 13bps
Althogh this bolt makes chops less often it still can chop if you shoot to fast. Also it won't help with the average field paint. This bolt will jam if you shoot more than like 16bps. I did that and it messed up the spring so I couldn't play until i fixed it at home. The ACS feature also requires that there be no o-rings on the bolt so expect to refill your air up often. Overall this is great for stock electronic spyders but if you upgrade your marker too much you'll start to have problems.
I recommend this product to people who don't want to upgrade until they get their spyder to 20 bps. This is great for a single upgrade to a stock spyder.

Leaks co2 a little
The end is kinda loose
Great for any spyder there is just the problem of a small co2 leak because its plastic and u can't put o-rings on it. Also the end is kind of loose. Like the metal on the end that u pull to cock but thats minimal.
It does work great and since i've gotten it i've had no chopped balls.
Something to fix the leak is a smart parts on/off valve. Its 15 bucks.

It occasionally saves you a couple chops.
It seems like it breaks paint on purpose.
This bolt sucks. Like I wrote in the strengths, it saves you a chop once in a while but other times, it chops paint for no reason. I haave a friend who also has this bolt and he calls it the autochopper. I think this bolt is a complete waste of money.
If you wanna buy a piece of crap that'll cause even more breaks than this is the bolt for you.
With my old bolt in my spyder I used to get about two or three chops a day. I may not be that much but still a pain to clean out of my gun at the end of the day.
I've used my gun with the ACS bolt in it for two full days now and after about 3000 paintballs not a single chop. It fit in my gun perfectly, its made of delrin so its lighter, and it doesn't have any o-rings so you don't need to worry about broken o-rings on the bolt which happened to me once with my old gun.
A brilliant product by spyder. Mine was very inexpensive too($35). If you don't have one of these and you don't want chops then you need to get one.

Haven't chopped a ball yet
Lack of o-rings
I never really had chopping issues, but since I slapped on an e-trigger, figured I would have issues sooner or later so I bought the bolt. I have shot about 1000 rounds so far and have not chopped a single ball (and I can get em going pretty fast). It was simple to install.
Now, what I don't like. On my Spyder Xtra, it is a pain to cock the gun. The rear action bolt is not easy to grab and pull. I wish it had a beaver tail or something of that nature. Second, I don't like the fact that it doesnt have any o-rings on it. The concept of air control just makes sense.
It does what it says, and I haven't had any of the problems listed in some of the other reviews. I am happy with the bolt, but there is room for improvement.

NEVER chops, easy to install, works perfectly
when i first got this i was very skeptical as to if it would work like it says it would. To my surprise and great staisfaction, it did work perfectly and i thought that it was a great thing to have purchased. Instakllation was easy, only took about 2 minutes. I Played with it this past weekend and didnt have a single ball chop.
This is a Must Have upgrade for any kingman gun, and for the price it litteraly pays for itself
