Trifecta Airsoft crew gives a quick review on M4 PDWs that they got from Evike.com. We know you'll notice immediately the trigger discpline... "Reviewing the three M4's from the last box of awesomeness by Evike. The Tanker, PDW, and Commando. The Commando runs a higher fps (370) than the Tanker and PDW (330) and would be fine to use on most fields. The T & P use a downgraded spring perfect for CQB fields. Thanks for watching."
