Burst FRT?

I was wondering if anyone knew of a 3 round burst FRT that’s either in development or that I’ve never heard of? I don’t even know if it’s possible but I think it would be very nice to have. Would be fun to shoot but have more control. And specifically I’d like it for my AR-15 but if there’s one out there for any gun I’d like to know to see how it works. Thanks in advance!
