I have decided I am sticking with my M4 S System and I am just going to pimp it up the wazoo and hopefully be able to transfer the parts to my next gun. So far this is what I have decided on: TMC PEQ-15 http://www.ebairsoft.com/anpeq15-battery-case-with-laser-sight-p-6014.html Aimpoint replica(decided on an Aimpoint style over an Eotech) http://www.shootercbgear.com/product_info.php?cPath=26_45&products_id=44 Element grip http://www.airsoftpark.com/product_info.php?products_id=10109 This crane stock http://www.ebairsoft.com/multi-purpose-buttstock-with-sling-swivel-p-4251.html Still stuck between this STANAG http://www.evike.com/product_info.php?cPath=23_56_439&products_id=28790 And this PMag http://shop.ehobbyasia.com/beta-project-pts-pmag-75rd-for-m4-aeg-black-abs.html Unless anyone has any suggestions of similarly priced pieces? Also what batteries can work with my JG? I have looked around but can't figure anything out. Would a larger battery work for me?
