This guide will show you how to convert, step-by-step, a Tokyo Marui G36C airsoft electric gun (AEG) into an SL-9 rifle.
It is also possible to convert a Classic Army G36C AEG, but apparently the parts are more difficult to fit and extra work may be required. This guide is only designed for the Tokyo Marui AEG so your mileage with other guns may vary.
Intelligence I can't help you with. The G36C can be purchased from almost all dedicated airsoft retailers. To save money I would advise importing from overseas retailers (Hong Kong retailers such as RedWolf Airsoft or WGC Shop.
You should be able to buy the SL-9 conversion kit and the battery from these retailers also.
If importing scares you, then you can purchase the items from UK retailers such as Airsoft Armoury or ZeroOne Airsoft. Incidentally, ZeroOne Airsoft sell various pre-built SL-9 models so if you don't fancy getting your hands dirty that is another option.
The hex keys and screwdrivers can be found at any hardware store, as can the glue.
Weak lemon drink can be purchased from most supermarkets, but for further advice on this you may wish to contact Simon Quinlag.
How long is a piece of string? I was given an estimate of three hours by some of the good folk over at Arnie's Airsoft but in reality it took me closer to four and a half hours. I would have been quicker, but I was writing down the steps taken and taking photographs so that I could produce this guide.
It is also very much dependent on your experience with disassembling AEGs. Before undertaking this project, I had never taken apart any AEG before.
It was easy, but even so problems can occur. That's where the intelligence comes in, it is handy for being able to work out what's gone wrong.
I can't take any responsibility for anything that does go wrong. If you do notice any mistakes in the guide then please do get in touch so that I can investigate and correct if required.
