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.

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.

Chops When cold
This will be the best anti chop bolt ever if you do not plan to play when it is winter. Its awesome no oring to worry about the looks make it very nice adds alot to your whole gun retail value. But the largest problem is that it does chop! Maybe not when its over 70 degrees but it will chop on you any more below that! Also you cant get alot of speed with this bolt because if you have it turned up to high it will again chop paint! But when the weather is warmer you can get an amazing speed through this bolt because it is again Delrin and being light as it is you will get a massive rate of fire though this bolt!
I will recommend this bolt for people who live in warm states all year round like texas or California.
Im giving it an 8 because you can get amazing amount of speed with this bolt, and it does not chop in the summer time
Good bolt for warm temperature do not use in colder play will chop put your stock bolt back in your gun.

Kingman ACS Bolt (Delrin)
Delrin, Close Fit, Quiets the gun a bit, Anti-Chop, NO VENTURI!
Feels like Cheap Plastic, Expensive ($40)
Wow, I was first skeptical about this bolt. After paying $40 for it at my local pb store I took this sucker outside and went full-auto/fast walking with a Vl200 Hopper hoping to induce a chop and to my surprise the bolt didn't chop (Made a weird noise when ACS activated). The bolts tight fitting with the body quiets the gun a bit and creates a nice effective flow of air.
I give this bolt a 10 because its a upgrade every person would want on his or her's Spyder. It will defiantly save you time in the field when your hopper cant keep up with your gun.

Ok, I know a bunch of you will dispute this, but this is my story on this bolt.
"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.
1 Out of 10 just because it chops more then a stock bolt. This thing chops on purpose... Buy it if you want to chop, and be busy field stripping to clean out a lake of paint inside of your chamber, buy it.

Mongoose 2 LCD, Crossfire HPA red 92/ 4500, VL Evo 2 hopper
Doesn't work at all, chops more then stock bolt
Okay, let’s just say I was an idiot for buying this junk.
My mongoose 2 LCD (spyder clone) didn't chop any balls during a day of play (with stock bolt) and about 2500 balls shot through it in different modes, semi, full auto (18bps), 3 rnd burst, 5 rnd turbo burst, etc.
I purchased this to try and insure great performance on my marker for long time to come. I was very disappointed in it though.
I paid I think $36.00 for it
Got it installed it shot about 4 balls through it and "BAM" chopped a ball. I cleaned everything up and thought I had a hopper issue (wasn't turning). So I cleaned out the hopper good took it apart and checked the eyes. Then it was working again???
So this Sunday I went to the field loaded her up and went to chrono. 3rd ball chopped so bad it blew paint up into the hopper (not allowing any more balls to fall).
SIDE NOTE: I also noticed I could not get my velocity above 250 fps with this bolt. I cleaned it about 4 more times and shot about 12-17 balls through between breaks trying to get the velocity up above 250. Haven't check since going back to stock but last week with stock I was at 280-290 fps?
Long story short this went on for the next 4 games, I tried CO2, my HPA tank, regular hopper, my friend’s halo, my Evo2. Still same results every 3 or 4 balls it chopped.
I finally cleaned everything and changed over to my stock bolt. Magic.... Suddenly I could shot semi, burst, etc. 10-200 balls with no chops. Actually I think I only busted one ball the rest of the day (using cheapest paint).
So I will have the good ole kingman ACS bolt on ebay if anyone wants it Cheap... hahaha....
Stock bolts on Mongoose 2's work 100 times better then this junk.
Don't waste your money if you have a Mongoose 2, it is useless.

spyder e99, smart parts 14" all american barrel, check it powerstation regulator, macro line kit, twist clamp feed neck, check it trigger, 25 gram switch, valve kit, acs aluminum bolt, 48/3000 pure energy tank, and black evolution 2 with z board
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.

O4 Imagine, J & J Ceramic, Dye Sticky Grips, Shocktech Bolt, Empire Reloader, CP Flame Drop Forward, 68/4500 Nitro Tank
Made of Derlin
Mine was DEFECTIVE
I bought my Imagine used with a few nice upgrades. The previous owner did not use it with the ACS bolt and it was still in its original package. I was anxious to install it and get out there to play. The next day was Frustrating I kept breaking balls in the gun and hopper. I had so much blow back the balls would go 20 feet up in the air with the hopper removed for testing. I put the original bolt back in and everything was fine.
I talked to Kingman and they told me that they had a bad original design and to return it for an replacement.
I have recently bought a Shocktech bolt that works GREAT.
I will update this review when I try out the replacement.
What I thought would be an upgrade turned into a downgrade. I can't recommend this bolt unless its replacement blows me away. Save any headaches and just get a Shocktech to begin with.

Chops, Chops, Chops!!!
I had a horrible time with this bolt in my flash! Put it in and choped after 2 balls. After that it was, chop chop chop chop... cleaned the barrel out and tried it again... and it happened again. I took it into my local paintball store and they messed with it. Took it home and fired about 8 shots before it choped choped choped choped. I gave up after that but i was told that on some of the bolts you have to compress the spring for a few nights before it is broken in. But still... wasnt worth the time and money. I returned it for a full refund. I was hoping that would end the chopping problem for spyders... didnt happen so i finally gave up and i am now a proud autococker owner. I wouldnt go back if you paid me!
Didnt work for me... hopefully other people had better luck than i did. I give it a 2 since its all delrin.
spyder Xtra, vl revolution w/ x board, 14" quiet riot, kingman acs bolt, 20 oz. c02
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
Spyder Electra acs 05
20 oz Co2
nothing special yet
No O rings
Doesnt stop all chops
Have to cock it when it detects a chop
Im not too happy with this bolt
it does not do good at all with my spyder electra 05. It comes with the gun already in it, but WHY would they put this in the Spyder electra 05 if it cant keep up with it.
I say it cant keep up with my gun because its too fast and its just not that good overall.
And when it actually does detect a chop, you have to pull it back because it wont re-cock.
That can hurt u in the middle of the game. Its also very annoying.
Get this only if u cant afford or dont want eyes.
It helps.. it will do its job if u have the right kind of gun.
Just dont expect much from it.. its just a bolt with a spring.
