I have to agree with APOC, even in the real world one of the reasons you'd want to use a semi DMR is for the ability to take quick follow up shots. To me the 1 second delay is too long to make that useful (I know upgraded springers are harder to cock, but on a real bolt action [or a gas bolt airsoft, I guess] -- accuracy aside -- I can cycle somewhere around that speed). And airsoft guns like the PSG-1 aren't crippled like that.
Where I'd see the most usefulness would be limiting both semi and auto to "semi" and using the mosfet to safely allow a higher voltage pack in order to reduce trigger lag. And while pre-cocking may not be possible, maybe a system of half or 3/4 cocking, to reduce how far the piston needs to travel when the trigger is pulled?
But yeah otherwise I think someone would be better off using a real BA.
