Anti reversing spring

[Double Tapper]

Well things were going good for awhile,my agm m14 was shooting spot on,
when I started hearing the spring unwind after firing a shot.I know I installed
the anti reversing latch spring correctly,has anyone else had a problem like
this.I have fired about two full high caps through it before this problem.

I tried editing,but it wouldn't work hence my second post.Are there
different strengths of springs for these anti reversing latches?.This
is the second time this has happened.

[Skladfin]

no there aren't any different strength springs.

sometimes the reversal latch spring could be too weak to push back the reversal latch before the gear unwinds. This has happened once on a Systema gearbox, they used steel reversal latch and that made it much heavier.

I replaced it with a normal TM one and it shot fine and happily ever after

[Double Tapper]

You are suggesting my my latch may be to heavy?,so I should
replace the latch and spring and this should solve my problem?.

[ThunderCactus]

Sounds to me like your spring broke.
And actually there ARE different strength of anti reversal latch springs, the stock springs are usually crap, I suggest a systema or prometheus anti reversal latch. It's a thicker spring so it's less likely to break AND it's stronger.

Or as a quick fix, you can try stretching the spring in the correct direction. I did that for an anti-reversal latch that was too strong and wouldn't let me get the mechbox closed without things popping out.

Well I finished opening my AGM to look at the spring,it is on the wrong side
again of the anti reversing latch.Are there different lengths to these springs?.
Though the bent part of the spring that hooks to the latch is straightened
out a bit.This is I think also the cause of my semi-auto problem,I observed
that when the gears didn't unwind,it would fire correctly,but when it did,the
lever was up half way and it would fire in auto.Either way,I need 2 new
springs.One for my TM M16 and one for my AGM M14,anyone have some
new springs they can sell me please?.

Get sets of gearbox springs from Airsoftparts.

[Kos-Mos]

Might be cheaper to simply but 2 new ARL.

[Double Tapper]

Spring sets ordered,I will update when I reassemble the guns.

i think my brothers kirenex has a problem like this. sometimes when you let go of the trigger it makes a whirr-ir-ir noise. thought the problem was the anti-reversal latch and opened everything up and checked it out and the spring on it was rather stiff so i dunno, the motors probly worn

and yea i hate that when youre trying to close a gearbox and everything wants to pop out. i dont have enough hands to hold down the anti-reversal latch, trigger mech, tappet plate between the gear and shims and bushing, and the spring pushing the cylinder up all while trying to close the gearbox

I've had this problem recently with two armalites I am working on. It drove me nuts because I was 99% sure I installed the anti-reversal latch properly. It turns out for some reason the latch wasn't engaging the gear properly. One way to test it out before you close everything up take out the cyclinder/spring/guide and turn the gears the other way while putting in a few screws to close the mechbox. Holding it closed with you hands doesn't work well enough. Just a few of the back ones should do it. My guess is that it will intermittently go in reverse. Try moving it back and forth. I also tried shimming the anti-reversal latch too. It seemed to help things a bit but make sure it doesn't interfere with the spur gear.

I should try this and let you guys know, I too have an AGM. At first I thought it might be a poorly made spring and I'm sure the ARL is installed properly. But as phalanx mention, it might not be aligned properly, especially with those helical gears in there. I noticed they are slightly thicker than standard gears.

Springs arrived Fri.I will install them this week.Will keep you up dated.
Thank Juggelz.

[Double Tapper]

Well the brand new springs is in both guns now.The AGM M14 is
now firing in both modes again,semi and auto,this seemed to fix
my problem and will be firing both for tests as soon as I reassemble
my M16.Thanks again jugglez.
