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.

No choped balls, no squeeging, just relax and play.
None i have found.
I bought this bolt for my spyder so i would have a decent back up. This bolt works great for me. I bought a elect frame and just shoot as fast as a spyder compact can keep up, and not one chop. dont need to recock or anything. I knew friends that have had E99's and their guns would always freeze up from shooting too fast because the broken ball wedged its self between the body and the bolt. My gun with this bolt has not had that problem at all. I would strongly recommend this product, it makes the game worry free from paint breaks and accuracy loss from them.
Good setup, you can basically leave the squegee at home. I give it a 10 because i have had no problems with it, does exactly what it was designed to do, its delrin..... and hell, i have a compact and i used the Imagine bolt, and still works flawless.

It works-everything you can ask for
still does chop on OCCASION
Me dad got this bolt for his Xtra because he has been complaining about mad chopping and both he and me are very glad he bought it. Being made out of delrin, you do not need to oil it (still reccomend it) which is a obvious plus to me and him. When we actually got to use it he was using a gravity feed hopper and very old brittle paint. I was shooting the same paint and I chopped approximately four times the amount that he did. When ever a ball should have been chopped, the bolt made a different noise then it usually does and the ball would fly out going about 30 feet. This bolt did everything it says it does and is well worth it.
Very godd product I recomend it to all spyder owners
At first I still chopped with this bolt even though it is anti-cop. I soon realized I was using horrible paintballs for this. Horrible for any gun. Once I got new paintballs it never chopped for me even on full auto for a whole hopper non-stop.
Twice it didn't shoot and I realized that was the anti-chop kickin in. The gun won't shoot and all you have to do is re-cock the bolt.
The only weakness is you need to have good enough paintballs for it but I should of thought of that at first.
I would buy this on your gun as an upgrade and if it comes stock you should prolly keep it.

Delrin - No Oiling Required
Anit-Chop System - works great
ACS Spring a little tight at first
Seems to cause high blowback
I got this bolt with the kingman e-trigger and a revolution 12 all at the same time. I knew I wanted a delrin bolt to save my marker body from scratches and this one was only 5 bucks more than the shocktech superfly so I figured why not. The E-Trigger is capable of outshooting the Revolution by a small margin, so I got a few opportunities to observe the ACS Bolt in it's glory. I was amazed at how ingeniously designed this thing is. My hat is off to kingman for this wonderful idea. It will simply not chop the ball, the ACS saves it every time. One thing I did notice was that there seems to be increased blowback up into the hopper from this bolt, not a big deal but it could be solved by polishing your striker and valve pin as described on Ottersccustoms.com.
I did get one chop with it. It was caused by the spring which is the main component of the ACS system being a little bit too "springy." I worked the spring vigorously to try to break it in and now it's working perfectly every time.
I give this bolt a 10, and I know that lots of products get a perfect 10 on this site and don't deserve it, but, this bolt is the most ingeniously designed thing I've ever seen. It is a perfect piece of engineering and IMO should come stock on every marker sold.
Spyder Rodeo, ESP LCD, Ricochet Apache, ACS bolt, 14 in' AA , 20 oz CO2
Dose what it says it will do. its derlin. No oiling
A little bit pricey, takes some range off if you use CO2
I went out yesterday with this bolt, and boy did it save my butt, I would have been choping balls left and right without this thing .I never poped one ball with this baby, and got some good bunkering. You can tell when its working, and its a MUST have for electro spyders. You might have to recock the bolt every now and then if your useing CO2, but with HP its clean living, and you get your range back. No chops with this thing. I recomend this bolt to all spyder users.
If your willing to pay 50 $$ for this bolt, go for it, its well worth it. You will want to get HP with this, but its not bad with out it. All and all a great and sturdy bolt.

14" J& J Ceramic
Olive Ricochet AK
ACS Delrin Bolt
20 oz. Pure Energy
Helps stop chopping most of the time.
I've still had chops with it.
I got this bolt at the same time I got my rico ak. i kinda wish i bought an eggy 2 instead of these two items. i still get chops when walking or raking. i've gotten 3 chops in a bag of zap chronics, which is a very nice paint. at first i thought it was just bad paint-barrel match, bu after cleaning it out, i realzed that the balls were breaking in the chamber, not the barrel. it's delrin though, so it doesn't need oiling.
If you want an anti chop bolt, then by all means pick this up. but i do recommend investing in a faster loader instead.

spyder imagine, acs bolt, dye stckys grips, cp flame drop forward, 14" teardrop, halo tsa, 12 oz co2
Doesnt chop at all!!
derlin doesnt scratch internals, the gun'll last longer
This is an awsome product!!
Just to test its capabilities i put my marker on full auto and put a gravity hopper, and geuse what NOT A SINGLE CHOP!!
Very good bolt, light, doesnt chop at all and barely any kick
nothing else to write and theres a 50 word minumum so just wasting space lol,
i think thats 50 words
I definetly recomend this product, very good and people who say kingman doesnt make good products, well, there wrong
should definitively be on your list of upgrades
phat 6 stage x chamber
14'' empire twister barrel
gravity fed hopper
delrin acs bolt
gravity fed hopper
Increases blowback= chopping
This bolt only caused me pain from the start....
Heres somebody elses story about this bolt, very similar to mine:
"It's an ACS bolt, but using a name the forum people have indicated to me, something known as the 'mystery chop,' the bolt will chop a paintball about every thirty rounds or so. No matter how quickly you fire the gun, your paintball will be broken. I stood outside and fired as slow as I possibly could for about thirty rounds before a paintball exploded inside the gun. This happened with quality paint and bad paint alike, it has absolutely nothing to do with the paintballs.
As far as I can tell, this is because the delrin does not confine completely to the paintball marker chamber. If you hold your mouth up to the firing end of the gun, with it unloaded and uncocked of course, you can blow air clean through this bolt and up into the feed neck of your gun. Using my stock aluminum bolt, I was unable to do this, thanks to the o-rings that aluminum bolts require. The extra space in the delrin acs bolt allows the air to go in crazy directions inside your gun, thus bursting a paintball regularly. This is probably the answer to the mystery chop people who use this gun get. I'm not the only one who gets this." ---- This is what DLITZ came up with, and i aggree 100% with him.
This is what happend to me... dont get this bolt... it has caused sooo many problems for me.
*Also this bolt caused so much blowback that it would launch paintballs back up into the hopper and make them implode inside the hopper, so i took my hopper off with a couple of paintballs in the feedneck, i fired and the other paintball left in the feedneck shot up about 5 feet into the air.....
Did not live up to its antichop name, for it induced chopping in my marker.
Go with the aluminum bolt, something with o-rings....
I do not know if my bolt was simply a manufactor defect or what, but it was horrible.
Dont get it, get anything but this bolt, you will only regret getting this.

Doesn't work with reloader b
Delrin cracked after one use
GARBAGE! For starters this bolt doesn't work with a force feed system it was double and triple feeding balls. and secondly it does TOO chop. The thing they don't tell you is that if you use a good loader it will become a milkshake machine. After the first game of speedball I played with it I took it out to have a look and the bloody delrin was cracked. (Yes it was installed properly) My advice is to just pick up a shocktech instead believe me you may still chop an occasional ball, but you will be able to use whatever loader you want.
Put your money into something of better quality, unless you play rec ball with a gravity fed non-elctro.
