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.

Spyder Imagine 04 (used with bolt)
Palmer Stab. Male Output
Check it Assault block
Delrin (no need to lube)
I bought this bolt for my back up Imagine, and it exceeded my expectations by far!! Some people might think 40 bucks for a bolt, but trust me, it is worth it. Even if it is your backup, it is a great feeling to know that what ever u shoot, wheather detent is messed, ball sucks, anything, it is great to know that break is impossible. If this were my main gun, i would not even bother bringing a squeege.
Worth it, if decision is pending, go through with it!

No chops and is low pressure.
Great job kingman! Kingman's new acs bolt is fantastic. I chose to buy the aluminum bolt, because I had a bad experience with a delrin bolt that i had bought in the past (but i have heard good things about the delrin bolt). This bolt eliminates chops. I was sick of choping in the middle of a game, and was seriously thinking about buying a t-board with eyes ($65) and maybe a rockin trigger ($125 w/ board aned eyes) into consideration. When my neighbor told me about the new kingman bolt, my eyes lit up and I imediately started looking at prices. Ask your local paintball shop if they will match the price of the bolt, so you dont have to wait for it to be shipped.
Buy this product!!! Hope my review was helpful.

Kingman ACS Bolt
No chops, duh
Cant think of any
I installed this in an e99 avant. It fits flawlessly, probably because kingman made them. I bought the delrin, but for $10 you can get aluminum. I use the empire reloader hopper which should feed at 13 bps, the avant can fire 14 bps. I never chopped in the case of paint i shot! I have a trigger mod so its walkable, and fast. Like i said, NEVER chopped. I even tried to make it.
BUY BUY BUY
BUY BUY BUY
Great product if you dont want to buy the t-board with eyes.
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?

Lives up to it's name.
Spring may weaken
I purchased this bolt on somewhat of a whim. My marker has been having trouble re-cocking after playing for about an hour. This usually means chopped balls in the middle of a match. While I've been working on the problem and testing solutions, I became tired to stopping to clean out my gun every match that I started chopping.
I decided to pick up this bolt to help ease the pain of my troubleshooting. I'll admit that I was skeptical at first because i felt the bolt compression and I thought that for sure it would still chop.
I of course tested it out on my finger but waited for a real game to pass judgment.
Lo and behold, my dreaded failed re-cock occurred. However to my surprise, when I re-cocked it myself and pulled the trigger, I did not have a wad of paint fly out of my barrel. When my gun flaked out 2 more times, same story.
I am very happy with it, and though I've complained about the cost, if you think about how much a bolt with no venturi or even a delrin bolt would cost, it evens out when you consider that this also stops the chops.
I am a little concerned about the spring weakening. In my mind, if it becomes too weak, the very act of the bolt firing may cause it to compress reducing the efficiency of the whole firing process. Only time will tell.
If you were considering buying a new bolt, pay a little extra and pick this up. It's worth it.
You get a delrin, high flowing bolt that will reduce or eliminate chops.
I got this bolt the other day, & immediately went to test it. I used a gravity fed hopper that I knew couldn't keep up w/ the bolt. I was trying to make it chop a ball. I wanted to see if my $45 was invested into a good product. Immediately I noticed much less vibration when the gun was on full auto, because of the much lighter bolt. I noticed a tighter grouping, & last but not least not a single chopped ball... Oh... I forgot to mention... The balls I used were very old, swollen, & brittle... I'm a cheap skate & was making sure it was worth that $45.
Well... It did exactly what it was supposed to...I was very impressed w/ product. It's made by kingman so you know it's made well. It was well worth the money & may actually be a better & just as simple upgrade as my tear drop. would buy this over a super fly or bandit.

It is overall a good product and does its job but its a little too expensive considering my stock bolt only got 1 chop every 6000 balls. I bought it to make my Spyder just like a Impulse and this product helps it do that. The catch is that this bolt doesnt have as much range as my stock one.
Get it i you have enough money and really want it.

Possible wear on the spring over time? (not sure)
When I got it I immediately put it in my imagine and stuck my finger down the feedneck and fired (without air), it worked perfectly. I then played around with trying to get paintballs chopped/jammed in there and it still worked like advertised. Then I aired it up, put on a VL200 and let it rip, zero chops. If I do this with my stock bolt I get chops galore. You can hear a distinctive noise when the bolt prevents a chop, sounds like a muffled shot, and the bolt continues to cycle like normal, you hardly know you almost chopped. The bolt does not dent the ball in any way. The bolt fit my spyder well, about the same as the stock bolt. The delrin bolt worked fine without oiling too. There is also a slightly reduced weight, so there might be slight velocity increases, however I did not test it over a chrono.
Very good bolt, good for the price considering other bolts cost about the same. Zero chops what so ever. I highly recomend it as a cheap way to stop chopping.

Spyder Imagine, 12'' Teardrop, ACS delrin bolt, Crossfire 68/4500, Rico AK, Smart Parts tank cover, Java alluminum feedneck.
*I now shoot an Impulse*
Delrin for smoother operation, no venturi, it seems to do as it advertises.
Nothing as far as I can see.
I have edited my earlier review now that I have had a chance to use this bolt for a while.
~Preformence~ This bolt does what it's supposed to do. Before my ACS bolt, I would chop and jam quite often. I would always have at least one major jam per day forcing me to sit a game out while I cleaned out the breech. Not with this bolt though. The ACS bolt has cleared up my problems dramatically. I have only had one chop with it (and that was because I was using old crappy paint, so it was my fault). Also, it's great that the bolt is made from delrin (even though there is an alluminum version), because it lets the gun cycle smoother and it helps reduce kick. Delrin is smoother than alluminum for less friction and it does not require any oil or lube, ever.
~The Test~ One day I decided to put this bolt to the test, and see how it really preformed. I used my Imagine setup that you see up above and was shooting PMI Premiums. First I ripped it in semi-auto mode. No problems whatsoever. So I switched to 3 round burst and full auto and ripped long strings of paint. I didn't have a single chop. There were some misfeeds but thats my hoppers fault, not the bolts. Next I decided to use a regular Vl200 hopper to try and make it chop. I again went back and shot on all three modes of fire. This time I had many misfeeds (and understandably so), but still no chops. I was impressed to say the least.
~Quality~ Many people say not to get the ACS bolt because it is made by Kingman, and their quality controll isn't the greatest or whatever. Well, I'm here to tell you that that is not the case with this bolt. Mine has worked flawlessly. The delrin shows no signs of swelling or damage of any kind, and the bolt has a nice fit with the inside of the body. Another nice feature of the ACS bolt is that is has no venturi, so it is high flowing. Thats good because most people remove the venturi from their stock alluminum bolts anyways.
One more thing I will point out. In some reviews and on the forums, people are saying you need to "break the spring in". Mabey this is the case with some bolts, but with mine it was not an issue. I took mine from the package, slapped it in the gun and it worked just fine without having to be broken in.
~Price~ At around $40 this is a good buy. Most nice bolts cost around $35 anyways, so the price isn't bad at all considering how well it preforms.
This bolt is definatly a good buy. It does what it's advertised to do (and that is to eliminate chops) and I am very happy with it. If you are looking for a new bolt and also want to clear up your chopping and/or jamming problems, then this bolt is for you. Kingman has definatly made a step in the right direction.

ACS delrin bolt
Egg II w/Y-board
I bought this bolt from my local paintball shop. When I say cost is a weakness I mean I paid $49.00 for mine, Although I have seen them on the net for less. I just played with this bolt yesterday, and I must say the initial performance was very good. I shot about 1500 balls, and I did not have any chops. I even forgot to turn on my loader, and shot on full auto.....no chops. I even noticed the gun was a little more efficient with co2. This could be due to the bolt not having a venturi. As you are shooting if you have a ball that does not load all the way, the bolt will collaps down. You just recock and go. No chops, No mess. I have not owned it long enough yet to comment on swelling, but so far so good. It fit very well in the marker, and the weight if the bolt reduced the kick. It's made out of Delrin so it will not scratch the inside of your gun, no o-rings to replace, and it is self-lubricating. All in all I am very happy with it.
I have not used any other Anti-chop bolts before. So I can't say this is better than any other, so I am giving it a 9. However, it did exactly what it was designed to do, and I was not disappointed in it's performance. If you are in the market for an Anti-chop bolt for your Spyder. I would recommend you take a look a what Kingman has to offer.
