Airsoft Gun Version 3 Mechbox Repairs

This week I have had many AK 47 repairs come across my bench for repairs and upgrades. After doing several I decided to grab up the camera and snap some photos for you. I was amazed at how well some of these came out and I posted them in a airsoft gun repair pictorial on the AGR website . Her is a nice close up of a version three airsoft gun mechbox.


I also have been adding alot of airsoft gun repair pictures to my Google web album. You will find more than 100 mechbox and airsoft gun repair photos here

Jing Gong M4 commando airsoft gun upgrades

Jing Gong or better known as JG has released several new designs of AEG metal gearbox models. These airsoft guns come out of the box shooting airsoft bb's 360 to 370 FPS. The hop up unit on these new aeg models is extremely functional. One downfall I have noticed with these is the plastic bushings that come stock, need to be changed out after about 3 months of moderate to heavy use and metal bushings put in. Do to a slightly undersized bore in the mechbox the holes must be slightly enlarged with a dremel bit so they will accommodate standard 6mm oily metal bushings. As of this date I have worked on 9 of these and they all seem to have the same issue. If you put in the metal bushings without doing this the friction will be to great and the gun will not fire. By just adding the bushings, re-shimming and lapping the gears my JG M733 now chronographs at 385 FPS.
