I was wondering when exactly roller delayed blowback designs went by the wayside? HK still makes the MP5 and some companies make clones of HK designs (such as PTR). But I cannot think of any newish rifles or light machineguns that have used roller delay.
Aside from the Sig 510 and CETME, I can't think of any rifles other than the HK 90 series to use roller delayed blow back action. Was it just a flash in the pan for European military arms back in the day?
