Well it would have to be tuned down from 30fpe but the P12 is closeto what you describe and if you can get it on sale or used theTaipan mutant is perfect just a tad over budget.You can also find used crickets for under $1000.Though I wish someone would make a bullpup similar to Hatsanbut not more than 7lbs for the rifle alone.
Is this too much to ask for?A lightweight, short carbine or bullpup that is quiet and accurate, multishot, gets about 20FPE over 60 shots per fill that doesn't cost $1000+
I just PMed motorhead But I am still intrigued by something like this as well that I found back in the archive: http://www.gatewaytoairguns.org/GTA/index.php?topic=94536.msg884822#msg884822Its got the power and the shot count.
This one ticked all the boxes:80+ shots at 20 fpe, really quiet, light, front cocking, free floating BSA barrel, 10 shot magazine. Bought a used Gamo Dynamax for 200 eur, added some misc. parts + lots of sweat and curses and turned it in to a bullpup for around 300 eur total. I'm actually going to use that stock and rail system for another bullpup build shortly. What you could do is to buy a used Gamo Dynamax or BSA Scorpion and then buy a bullpup kit for that from guntuning. Total cost should be around 600-800$.
