I have not done my official Table Top and Shooting Reviews for the Gas Blowback Airsoft Cybergun Sig Sauer P226 but I really wanted to cut off the ugly orange painted barrel tip, it was kind of driving me crazy! keep in mind here in Canada we are not required to have orange tips on our Airsoft guns, most of the all metal or all black Airsoft guns imported these days fall into the "airgun uncontrolled firearms" category. If you live in the US or other parts of the world you could be breaking the law if you do this mod so be warned...
Your best best is to simply watch my Vimeo Video as I show you exactly how I removed the orange painted portion of the metal barrel using a hack saw, file, vice and some sand paper. All in all it was not too difficult and only took about 15 minutes to complete...
