Stock Marui MP5 SD5 AEG The Marui MP5 SD5 is a good gun for medium range games. But I wanted THE perfect SD5, hence the mods.
Functional Mods
EG700 Motor
Systema HI-Speed upgrade
Match Inner barrel
Form Mods
Mosquito Molds MP5 aluminum frame
The Mosquite Molds metal receiver is warped. The front and back end does not close. I went and got a couple of clamps and clamped the two ends close. I then stuck the receiver in my car and on sunny days it warm up the receiver . This seem to worked, the warpage is less severe and I can acturally close the two halves together with screws.
KM aluminum suppressor
Initial Tests:
Braving the bitter wind I went to my backyard and chrono'ed the SD5. The gun shoots around 244FPS plus-minus 3FPS. I tried to do a ROF test but at 5 feet the bbs went through the cardboard box I was using as a BB trip, hidding the wall behind it and bouncing back at me. I'll try it again later with a better set-up.
Range Time (Pre-Mod):

Chrono Reading:
244fps with .25g bb
Rate Of Fire:
The rate of fire is determined by loading 50 bbs in the magazine and time it takes to empty the magazine is then recorded. The data is then plugged into the formula:
50bbs/5second=Xbbs/60second where X is the ROF.
@ 600 bbs per minute
note; Hi cap Mags shoots around 23 bbs per wind
