ACK!!!! Get rid of that CP reg and put some AKA goodness on there! It will make a huge difference, especially once you get the MQ2 on there. The belsales EVO ram and QEV's is THE best ram setup you can own (the eclipse and Belsales rams are identical except for the eclipse logo). Yeah, definetly new feedneck and take the drop off. A good replacement would be the eclipse SL rail&ASA combo. CP's are ok as well. So basiacally you should get....
-Belsales EVO ram w/belsales or eclipse QEV's
-AKA Sidewinder or 2 Liter + inline reg
-New ASA & Rail, Eclipse and CP are good choices
Other than that once you get all the parts on, including the MQ2, you will have to change your pants every time you shoot it
Seriously, bring extra pairs.
