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 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.
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.
Two friends from work and I all bought Spyders about the same time. My buddies had problems chopping, I had concerns over the amount of wear I had already encountered. To solve our collective problems, we all bought the ACS bolts. Two delrin, one aluminum. Immediately, we had chops. My first chop period. Their chops actually seemed to increase. Then I played mine this weekend and had a nasty chop during a game and had to call myself out because I couldn't clean my gun and loader. That was the only problem I had, but it makes me wonder how good this thing really is. Anyway, if you have $30-40 to spend on something you don't know if it will work or not, then get one. You may love it like everyone else. Personally, it has one more weekend for me before I send it back to Kingman.
Beats me, it's light and doesn't wear. But my friends and I seemed to chop more. Only time will tell.

Hpoefully more to come!!
Easy to install, no oil, no o-rings it does what is says it does.
A little expensive.
Works so good i'll need a new hopper to keep up!
I was a liitle woried about buying this bolt at first. There were many mixed reviews and i was torn between this one and the Supa fly. Thankfully the pb store that i went to, to buy the other bolt, sold it before i got there so i had to order the ACS. What a blessing! I went through 2 hoppers on full (fast) auto without one single chop. Before the new bolt i could never get past 3-5 balls without chopping. The gun shoots so much better and I dont have a single regret.
Save your balls! Buy the bolt, its worth it. Delrin ACS worked for me!
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.

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.

I've never used an anti-chop bolt. All I have used was the stock bolt.
I have an Imagine 04 with:
14" J&J Ceramic
ACS Delrin Bolt
MaxFlo tank and reg
made of delrin
I have actually chopped
I put this bolt in my gun because I had experienced an occasional chop. I bought a reloader at the time that i got the bolt. I have not tried it without my reloader. This bolt seems to do what it is designed for. I experienced a few chops with very crappy paint. This paint (honestly) has spots where it is totally flat. Some of them look like eggs, or sugar cubes (it must be really old). I haev played with this twice now and have been very satisfied. Not one bolt break since I have been using good paint with it.
After some use, my bolt began to cause serious blowback which caused almost all the paintballs to bust. I changed to the stock bolt and it works fine.
I would recommend this bolt to anyone that is having chopping problems. I would probably spend the money on a hopper first though. I give it a 9 because of the price and it won't stop a chop on extremely crappy paint.
Get the aluminum version instead, something to help with blowback.

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.

I love this bolt!! I have never had a problem with it and it does exactly what it says. I would shop around on some of the websites, I would not pay anything more then 40 for it. I have heard some people say they got there's for 25 so shop around!!!
It is a great upgrade and I highly recommend getting this bolt

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.
