Hey peeps been having some issues with Ultra Ac's that I'm hoping you have experienced as well so that I can link tech support and hopefully get it sorted.
So here's the issue I bought a Roughneck and put 2 ultra ac5's on it went into a match and fired once only and had both ultras jam simultaneously and then died as my srms were too far away to do any damage.
I've also had the same thing happen in my King crab that had 4 ultra 5's on I've had all 4 jam at once after just one shot.
This has happened both pre skill tree and with the mechs fully skilled as well.
all the ultras have done it to me so far but oddly not the two's yet.
So if this has happened to you please comment below also if you have video proof could you please post it as well.
Thanks for any replies and thanks for reading

Did you double tap em? Because they will do that!

[qS Sachiel]

Cannot comment as I don't use is uac enough, but have received second hand complaints from unit members that do: first tap jam. You could try to recreate in training grounds if you wanted to avoid frustration of it happen in deployment.

Despite this persistent meme of UACs jamming when they shouldn't, there's still zero credible evidence.

Every single time.

No just press the mousebutton once an insta jam so frustrating and it don't matter if it's a single uac or multiples

[9thDeathscream]

Ive had uac's do this. Its not very often though. Id say 1% of the time. But it does happen.

[Excalabur50]

It seems to happen to me about every 5-10 games sometime more depending, my third match with the Roughneck the damn things jammed 15 times in the game, not after just one shot though, but they seem to jam an awful lot for me and skill tree be damned

[El Bandito]

I have yet to see any evidence of UAC jamming before it shoots the first shell.

[Dee Eight]

It jams after the first projectile leaves the barrel, even when you just hit the fire group # on the keyboard ONCE. Its not a mouse bounce issue on the clicker.

[DrSaphron]

Something to look into is that the sensor in your mouse might be going out and "double tapping% when you don't want it to. Ultimately you might just have awful luck and need to work on your situational awareness

[kf envy]

thus is why I stopped using UACs an just AC or LBX nothings more fun then getting UAC jam on there 1st shot in chain fire as you holding down the fire group key.
FYI PGI fired the guy that programed weapons before he was done removing the bugs an getting them all set up. this may be an on going side effect from PGIs doing.

[Champion of Khorne Lord of Blood]

To be honest, jamming on the first shot isn't the only problem here, having multiple jam up at the exact same time as often as they do also seems to be a common problem.

Having something like 4 UACs all jam at once is an extremely low chance, but it happens rather often. Note that if all your UACs have a 15% chance of jamming, having all 4 jam at once is a 0.05% chance if we're going by mathematical probability.

There was one, actually


I can't remember who or where, but there was one
It showed UACs fired on recycle (button held down) jamming

[Jay Leon Hart]

There was a thread with rigorous testing. I believe the conclusion was a double tap due to latency issues - ammo is consumed for your first shot and the server thinks you double tapped and rolls for a jam.

It happens most with UAC2s due to the lower cooldown and more often when the mouse is held, as opposed to tapped.

I was unable to replicate the issue with only tapping, using UAC2s and UAC5s, but had the issue frequently when holding UAC2s and infrequently when holding UAC5s.

[Brain Cancer]

Also, people think the "random" number check for a jam is a timestamp- so if you fire multiple UAC's together, they're all checking the same seed number. If it comes up "jam", it locks everything up together as well.

[Jman5]

There was a bug once where the Night Gyr had this problem with its torso ballistic slots. It got ninja fixed eventually, but maybe this bug is back on other mechs.

Weird thing is that I could only replicate it on the Night gyr. The other mechs I tested jammed as expected.

Most people mistake simultaneous jam for one jamming before the other one unjams because you don't immediately notice the first one jamming up until the second one stops everyting. True simultaneous jam should be rare. If it's happening several times a game on a uac/5 or 10, there is probably something wonky going on.

To be honest, I wouldn't be surprised if there is some bug going on with jam chance. its random nature makes it tedious to test for and hard to notice.

Button held jamming is a different bug than what I am talking about. I am talking about alleged UACs jamming before firing the first shot.

And only you are talking about it, which the rest of us keep wondering about... since nobody in the thread said it jammed without firing the first shot. We've all (that have had this happen) said...it jams after the first button push...which means after the first projectile clears the barrel and then it jams up.

When the first brought in the skill tree to pts... the 15% extra anti-jam chance produced an opposite effect when paired to a mech like the dragon 5N with a 40% base anti-jam quirk. In multiple tests I got 28-30 double taps off consecutively without jamming even once. I reported that in the pts forum and that's likely what led PGI to reduce the % per node from the original 7.5% to a mere 2.5% by the time the patch went live.

i have no hard evidence of this myself, but i would say that uacs are really buggy if you use 2 of them on a single fire group and both are arm mounted. With 1 uac, ive had a few bad games (3-4 jams in a minute or so of sustained combat), but generally speaking its fairly reasonable in how often it jams. The instant i use dual uac-10 or uac-2 ive had some really derpy BS. Ive had games where i literally had 5 or so DOUBLE jams in a bloody row, the second i go off cooldown, fire once, then jam, multiple times in a row. I know it is RNG, but sometimes it makes me think there is something rigged with dual uacs (ive had a triple jam on a triple uac mount maybee once or twice in the entire time ive played the game, but never multiple jams in a row one after the other like with duals).

Anyways, i know its probably paranoia (and i have no hard evidence or recordings to back up my claims), but ive basically given up trying to run dual uac-10s (at least uac-2s have a super short jam time) since i get so many bad games with dual 10s (seems to be most prevalent if the uac-10s are arm mounted, mad2c-d is guaranteed 2-3 double jams per game with the occasional 10+, mad2c-a, hunch, ect is a little less screwy but still ive had enough derpage to reconsider the dual 10 build).

So yeah, no idea if this is just my luck (probably), but dual uac-10s are a no-no for me, 2 uac5+uac10 is reliable, single ballistics are reliable, any amount of uac-2 is at least very low jam duration so its not that punishing in sustained fight. Guess too many complained about quad 10 kodiak and that gun got nerfhammered so hard its barely useable outside of single mounts (even then if it does jam its got such a long unjam time its super risky).

I never said before, it fires one round then jams and both or all weapons at once so you are left with nothing but your back up weapons I almost never run without backups, it was happening to me so much I converted my King Crab to straight AC5's
