No breaks. Period.
No breaks... ever.
Too stiff at first, need to break-in
I originally got this bolt because I play a lot of scenario games, and when switching between my cocker and Ego, I sometimes would short stroke when trying to shoot 9 or 10 bps. And in large scenario games, if you chop, it's going to ruin your entire day... especially with a cocker.
So I ordered one off of madcocker.com, and it got to my house in a timely manner with no problem. Iíve heard some people online complain about Jamm enterprises screwing them, or the bolts never being in stock, but I checked before hand, it was in stock, so there was no problem delivering for me.
When it got here, there were no instructions with it. Iíve heard from various sources online that you need to break these things in at first, since theyíre really stiff right out of the package. And true, when I fired her up the first time, I stuck my finger down the feedneck and it hurtÖ that thing was stiff. Nowhere as hard as the stock bolt, but the spring was really really stiffÖ stiff enough to wear it still broke paint. So, I dry-fired my cocker a bunch of times with a stick-squeegeeÖ still too stiff.
So I unscrewed the endcap of the bolt (you can disassemble the entire thing pretty much), and cut the main spring myself. Now, itís really nice and doesnít break paint. I actually tested it out with a paintball dangled half way down into my cockerís chamber. No break, sweet!
That was in June and now itís December, and I havenít had one single chop in my cocker. And I play a lotÖ especially scenario games. I played all of skirmish d-day, went through a couple of cases, and it preformed great the entire time.
Some things that I have noticed, is that now that the spring is really light, the bolt is really loose when the marker is cocking back and forth. This means that itís not as fast as super fast bolts on the marketÖ no concern to me however since I only really need to go 8 or 9 bps at max on my mech cocker.
My main problem with my looser spring is that the bolt pull pin is much more loose in the bolt, and every once in a while when Iím shooting fast on my cocker, the pull pin flies out. This is not good. However, itís only happened twice in the past 6 months and Iíve found it both times. I do however, carry an extra pull pin with me at all times.
Try as I may, I canít make this thing break paint. Iíve seen it double and triple fire like in the online videos, this thing works greatÖ exactly as they say it will. Not one chop in 6 months, thatís incredible.
However, it is a heavier bolt, and isnít super, super fast. If you are playing more speedball with your mech cocker, and donít really ever chop, then this is a waste for you. However, if you have any problems at all chopping, and speed isnít your number one concern with a bolt, then this bolt wins hands down. I gawk about price, but Iíd easily buy it again if given the choice again.
Spring needs to be broken in, not as air efficient as the stock bolt.
There might be a few people that would not justify a $300.00 E-blade upgrade on an Autococker as whatever version it maybe not being the most affordable one even to it's very basic platform. Depending maybe on your usage of the marker, it would be just great to have an electric trigger with anti-chop eyes and the ability to shoot all the paintballs to your hearts desire but as of course with every great upgrade comes a great price. Lo and behold, maybe not, enter this little sweet piece of mechanical ingenuity from Jam Enterprises. Amazing, just absolutely amazing. Took out all the frustration out of short stroking and "Autochopping". Case and a half of some Draxxus field paint and not one break. The usual short stroking that happens to even the most experienced cocker players are just completely solved. It may not offer air efficiency as compared to the stock bolt but compensates for the actual game satisfaction rather than cleaning your marker half of the time. Squeegees worst enemy I should say, not once I have to use it with this Jam bolt.
The best $55.00 dollars you would ever spend on an Autococker upgrade. It's not anything that's for cosmetics but might just be able to make You and your marker up it's value in comes to just actually enjoying the game. Go to Madcocker.com for pricing and more reviews.

None really, the new delrin ones are light as hell!
Anyone who says these are heavy is high, because not onnly are they light as hell but now you can up your cocking pressure to make it faster that will more than compensate for any measly 10 gram difference in weight! these guys were so cool, they couldn't ship immediately so they shipped express at no extra charge! and they were super helpful! the best part for cockers ever made with awsome customer service for a super reasonable prices! what else could you ask for
