SIP/JL Exhaust spring M210

Hi guys,

Further to my previous post does anyone know what is the best position for drilling a hole in a Malossi 210 Barrel to accomodate the forward spring when attaching a SIP pipe?

I’m slighly concerned the spring will ‚chatter‘ in the aluminium and wear the hole into a slot!

Thanks,

Jim
