Ak-47 feeding issues
 

HiI have a modded Ak-47 with the original hop up. I bought some G&P mid-caps sometimes ago. I never noticed feeding problem until recently: on four shots, there is only one bb coming out. I tried my old Echo 1 hi-capa, results is better but still 50/50. Is it my mags or can it come from somewhere else? Thank you

Couple drops of silicon oil down the loading tube in your AK, dry fire a burst or two, then run BBs through it. Likely it's a plugging issue form lack of lube. This happens around 90% of the time when feeding issues are a problem, totally sticky hop up rubber problem. Other times is mas not feeding right, but if the problem happens among various types of mags, it's the hop up unit that is the cause. The rubber should be lubed every few thousand shots fired, unless in a very dusty/sandy area that you might play in, in which case every thousand or so as needed.

Thank you, I will try that right away! ^^
