Another video for those diving into their AEGs to take them apart and change the parts for better performance. In this case, it is changing the battery connector, especially replacing the Tamiya Connector as shown by Reaper Airsoft... "Today we go over how to replace the small tamiya battery connector on your airsoft gun."
For those who are just about to do their maintenance or repair of their AEG gearbox, here is a video from Reaper Airsoft how to do it. Watch and learn... "Today we take a look at the normal walk through on an Airsoft AEG Repair. AEG Bearing Failure and Stripped Gear set."
Reaper Airsoft reviews the Elite Force Beretta M92A1 CO2 Blowback Pistol. Made of full metal, this has an initial muzzle velocity of 350-380fps and in this Chrono, this goes to 274fps on 0.30g BBs, and powered with 12g CO2 cartridge stored in the magazine. This can from semi-auto and full-auto so this can be a beast in CQB games.
