weird trigger behavior on SAR1

I've got approximately 500 rnds through my SAR1 now. Just recently, the trigger does something funny about once every 15 shots. After firing, it doesn't come all the way forward and I'm left with a hair trigger scenario. Breathing on it will make it go off again. I'm wondering if I won't end up with a multiple shot burst rifle pretty soon.
Although that might be cool, I rather keep it in semi-auto.
Any suggestions on what needs adjusting?
This is shooting wolf or barnaul ammo.
 
clean and oil the trigger group and see if it still happens, it sounds like fouling is not letting the sear reset fully.
 
I had something simular happen to mine. After nearly every shot I had to nudge the trigger forward to engage the sear. (I think I have my terminology correct! :))

The problem I discovered was where the trigger comes through the receiver. The rear of the trigger was catching on the rear cut of the receiver. A small metal file did the trick and now I don't have to push the trigger forward to engage the sear anymore.

BTW, this problem showed up after about 500 rounds as well.
