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.
Delrin, does not allow chops, no venturi, nice fit without o-rings, light weight
Some will say price, but not I
Although price may be a weakness is some users eyes, mine cost $38 and I feel is well worth the cost. If a bolt keeps you from chopping paint, saving you money and time, isn't it worth it? Imagine having a ball feed halfway into the breech then get stuck and splattered by your average bolt. How much time will it take you to clean this to get back in the game, or will you just walk off and wait until the next round?
Although I am a newb, I have done much research on all my purchases. My equipment combination, including this, has allowed me to step into a local indoor field and be more than competitive with younger players (I'm 41). In fact, of 4 games, I was only marked once (the last game), but my teammates were all gone and I got flanked on both sides...what could I do!?
This bolt can be found for less than $40 online. It is worth the money to keep your marker from chopping balls and keep you in the game. No o-rings to wear or break, no lubrication, and no chops...what more could you ask for?

nice spring action
Very persistent in chopping balls
This is the best chop bolt EVER!!
First one defective(see review)
This is the best chop bolt ever
I got this bolt from action village for $40. I got it along with my new imagine 04 because i heard the stock bolt scratches(it does). I put it in my gun and started shooting. it was working pretty well. then after about 100 balls it started chopping. it would shoot back into the hopper and my balls would break. I would have to take apart my whole hopper and run it under water(once it took the electronics out. ) It happened about 5 or 6 times. then i decided to call kingman. I was on the phone with this guy, he said to try the stock. The stock worked flawlessly(still scratches) he said that it was a problem with the size(it was too small; a minor defect). So i sent it back to action village. At that time the price had dropped to $30 so they gave me $10 back for the difference. I have it now and have not had a chop since. It is the best bolt(and only) i have ever seen. Lost my squeegee...doesn't matter! I sometimes put my finger in my vertical feed adapter and shoot it, it hits my finger and then the spring reacts and it doesn't hurt(i know its stupid but i was kinda bored. Don't know why its rated a 9??? [no points off for defect]
UPDATE:May 25, 2005
Everything in this review is a lie. I'm so sorry I lied to you. This bolt should not be called the anti-chop bolt they should take the anti out! Every 3rd shot.. balls would go voom...voom...grrrrrrcchhhhh!!! "Sorry days over gotta go spend an hour cleaning my gun."
I made a list for cleaning it chopped so often:
1. Take off hopper
2. open hopper
3. take out electronics
4. run under water
5. take feedneck off of gun
6.take barrel off
7. clean barrel under water
8. take bolt out (and curse at it)
9. run squegge through gun
10. let dry
11. Put Every little thing back together
12. your off and shooting
13. shoot 2 balls
14. Repeat steps 1-13
btw I sold my whole gun on ebay for $310
looks "Un"cool every time i see it. I know its doing "NOT" its job.

Lighter, no lubing, less kick, no chopping
Wow, a huge improvement over stock. Since it is made of delrin, it is light, and so there is a lot less kick. Also, I can't get it to chop. I pull the trigger as fast as I can with my gravity fed hopper and it just refuses to break a ball. And i'm using some Diablo Heats that are over a year old. Amazing! The stock bolt chopped all the time, never had one in over a case with this bolt.
But it Now!! I got mine for $35 shipped on eBay, and it was well worth it!

Delrin maybe or not
Does not work in electro-pnuematic gun
Well, after my tigershark bolt swelled up and would fit in my gun I decided to get a delrin bolt. This bolt was 50 bucks at my local shop. When I put it tin my gun it seemed to fit fairly well. When I shopt the gun the velocity was really low and had a ton of blowback. i tried to shoot a little faster and it chopped. The spring in the bolt depresses when the gun shoots from the solenoid, I guess the pressure is too great for the spring. It was a waste of money for me. If any one is interested i will be willing to sell it.
ONLY GET IT FOR A SEAR TRIPPER!! will not work on electro-pneumatic, even if you lower the lpr pressure.
Well, I have no complaints about this bolt. My stock bolt would chew up balls and spit them back out. With this bolt however, if a ball isnt in the perfect spot to be fired, the spring absorbs the energy of the bolt, and the bolt recocks and the ball is spared. No ball breakage has been caused by this bolt.
For being designed to prevent chops, this bolt has succeeded in its objective.
Drop a little money on it if your marker is chopping balls. It makes the game so much better. Now you wont have to clean your marker after every game, and with less balls breaking, your accuracy skyrockets leaving you with more fun during the game.
I lubed up the parts on the bolt that moved, and it works great!

14" smart parts progressive
Custom drop forward

*Now I shoot a B2k PDS*
Light, durable, delrin, accurate and quiet, cheap if u know where to look
None at all !!!
Well, i bought this bolt off the internet for about 25 dollars. at first, i have to admit, i was kinda skeptical of this bolt's ACS abilities. It took one minute to take out the old POS bolt from my imagine and to slap in this one.
Alright, first day paintballing with this thing. At the time, I had my richochet AK (now have a b) , and it worked fine, but i got a microswitch upgrade, and was now shooting 17 bps, too fast for the AK.
Well i was shooting strings of paintballs when i heard my gun stop and sputter.
THE MOMENT OF TRUTH. WOW! i checked my gun and no chop. the spring activated and saved me the time consuming squeegee. I just recocked and continued.
This happened several times, i out ran my hopper about 20 times that day, and not once did i ever come close to chopping. AMAZING. sometimes, it didn't even need reckocking, it just sometimes pushed the paintball into the right position.
THE BEST UPGRADE THERE IS FOR A KINGMAN. NO EYES NEEDED!!!
Definetely worth every cent. Makes the word "ACS" really come true. Saved my butt many many times. Toss out your squeege, you wont need it with this thing. Truly amazing. BUY IT NOW!!!

No blow back
Broke balls in hopper from blow back
I got this bolt in december and when i used it i broke all the paint in my hopper. it has happened like 5 times. i heard kingman is replacing bolt because of these problems, so i called them and sent my bolt to them. i got my new one back right when they said i would, and costumer service seemed pretty good. i went out to test it and had barely any blowback, and it wasnt chopping. it did make my velocity really high though, and it seems a little harder to break in. overall it works pretty good now.
If you buy one of these(especially for 04 imagine) make sure you get the new version if the bolt. If you don't you will have really bad blow back, re-cocking problems, and low velocity. The new version has everything fixed except now the velocity goes too high.

I first used this bolt a while back on my gun when I went to a field. The product itself works prefect, other than the one that I had(Ill say mroe about that later). But I used this product for a while and then I noticed I couldn't shoot, So I looked down, and my bolt was jammed on something, and to my surprise instead of chopping it, it just flexed. So i was grateful for that because I didn't have a squeegee. You actually dont really need one. After a couple of games I saw that my balls were swerving like crazy and the feedneck had a bisted ball in it. That happened like twice and I was getting mad. It was my bolt, it had alot of blowback on it. I go and call Kingman, and it happens to be an older model of it, and they happen to have replacements ot it. So yeah, I am getting a new one soon, and that should fix the blowback so I don't bust any balls in the hopper.
I recommend that you get this for a spyder. $30 online price, and it doesn't scratch your gun. I rate it a 9 because I had to return it because I had the older model, but I am going to put 10 because I want everyone looking to get this product to defiantly get it. Much much better than the stock.
Stock Bolt - Not as light and chopped like crazy
Shocktech Supafly - Not as light, and chopped at least once a game
E99 Avant with:
>14in SP Teardrop
>Kingman ACS Delrin Bolt
>32* Expansion Chamber
>Shocktech Blade Trigger
> No chops
> "Self Lubricating"
What an amazing product by Kingman. I just wish it came in different colors. You might as well just throw out your squeegies, because this bolt will never chop. I was playing in 35* weather with CO2, hoping this bolt wouldn't chop, and guess what, it didn't. This bolt is simply amazing and to keep it working amazing, keep it clean and in good shape. Also, NEVER lubricate because delrin will swell and the bolt will be stuck in your gun. If this happpens, the only thing I can say is good luck hammering it out!
I just did a test with my bolt and a VL 200 round hopper. That's right, a standard hopper. The results were amazing. I just ripped around 10 BPS (i could go faster) and absolutely no chops. You can tell when it prevents a chop by the noise. You can hear the spring working.
People have been complaining of blowback problems but I've had none. The people with blowback probably have the generation I bolt. I have the generation II bolt, and that's the one I'm writing this review on. Make sure you get the generation II bolt if you pick this bad boy up.
Buy this bolt if you want your marker to stay clean from paint, and never jam on you.

Expensive And Does Not Work Well With My Beaver Tail.
I have not fully tested this bolt out in a game type situation, just mostly trying to get my gun adjusted in my backyard. I did however chop one ball in about 50 I shot but I believe it was partially due to the age of the paint, so I do not believe it was the bolts problem.
All in all I am very happy with this bolt and I view it as expensive but a worthwhile upgrade. if you are like me and are comfortable with your Spyder and don't want to go buy a new gun, this is a good upgrade to get your gun up to par!
I give this bolt an 9 of 10 because I have not fully field tested it and I did break a ball (unknown if it was the bolts fault or not).
