i was also wondering about this as i have about 20 hybrid mods. my thoughts are someone should offer a replacement (brass?) 510 that could be installed by drilling it out and replaced or perhaps like helicoil?) in a worn 510. i'll be interested to see any replies here.Anyone know where I can find a replacement hybrid disk for my favorite mod. i dropped it causing my mterk to strip the threads out of the copper. Attempted to repair by using a 7mm x .5 chasing tap, but failed.
Please help!
