That BB Guy got this list to explain to you the five reasons that your gas blowback airsoft gun canno mag dump... "Does your gas-blowback replica have gas efficiency issues? We are going to look at 5 reasons that this might be the case. Although some airsoft guns are absolutely terrible with gas efficiency, there are things that you can do to help. If you have any of your own tips, go ahead and leave them in the comments to help others."

A quick video from Nonocat as gets rockin' and rollin' doing a mag dump of the MP5A5 and MP5K  Gas Blowbacks from VFC... "So many have asked/tell me that "the VFC MP5 GBBs aren't that good. Especially feeding and gas efficiency"... In one way or the other.

I personally would reserve this comment for the Stock Gen 1s or the declining QC that may be found in some Gen 2s.

If you have time and get pleasure from watching airsoft gas blowback rifles, here is something for you. I AM AIRSOFT got some friends to do mag dump of 10 gas blowback rifles and some are familiar faces here such as Stewbacca. As to what gas blowback featured here, these are the VFC HK416A5, VFC HK416D, VFC PSG-1, Tokyo Marui AKM, VFC BCM MCMR, VFC MP7, and the WE G36.

Enjoy watching!

USAirsoft gets behind 2 riot shields and try to survive a barrage of BBs as 20 airsofters magdump on him in this video... "20 Airsofter Magdump VS 2 Riot Shields. I really gotta thank Tactical Airsoft Arena in Manassas, Virginia for letting me do something like this and I gotta thank Michael Martinez for lending me his footage so I could get a second angle of this barrage.

It really smelled like smoke after this."
