so I have AxisofOil and Ryuuken to thank for helping me build a badass M4.
I spent over 9 hours today surfing and finding best prices/items and discussing it with those two guys and in the end, this is what i settled on
http://www.airsoftpost.com/product_info ... s_id=31055 - Silencer
http://www.airsoftpost.com/product_info ... s_id=31599 - Spacer
http://www.airsoftpost.com/product_info ... s_id=25958 - Bucking
http://www.airsoftpost.com/product_info ... s_id=25869 - Cylinder
http://www.airsoftpost.com/product_info ... s_id=31457 - Spring
http://www.airsoftpost.com/product_info ... s_id=32183 - 455mm 6.03 tightbore
hopefully, it'll perform well. altogether i've spent about $110 on upgrading my $150. does anyone have a chrony that i can test it with to make sure i'm still TAC legal?
