they discontinued them early this year i think.
but basically they cost more than the already popular SFT shocker.
then they started putting the nerve ramping board in all shockers so nobody needed to buy a nerve for 1200 when they could get a shocker for 600. in all honesty it was a better deal to get a shocker and buy the upgrades that came on the nerve already. freak barrel and qlock
nerves are a great gun and were and still are under rated. i just bought one that was barely used with a blackheart board for $150. i had one earlier this year but traded it. very reliable markers
