Got to say the shipping n packaging was really simple but effective, however the product its self was a very poor replica of the G&P model as it had jagged seams, the "parts" it came with were either again poor quality or chipped/ broken.. therefore i cant really put the receiver on my m4 for the poor quality.. but i guess you get what you pay for.. and i was silly for believing you get what you pay for..
Expect to see a video Review of this product on my youtube channel: ThisISAIRSOFT1 around October
