After a lot of test fires on my Recon, it started making weird low whistling noises whenever I prime it. Am I stressing the blaster out? Apart from this, it's completely fine and did not reduce the overall performace at all. But I'm just curious, are these sounds normal? (PS, I have a Realiator so please do not tell me to buy one.)
