Selling a Rare/Unique SD6 MP5 . This gun was imported and is from 2004 from japan directly to toys 4 war inc has all of the orginal import documents for customs. Originally Branded gun. Reason it's unique is because the trademarks were "removed" from the factory before importing (see pictures). I've never seen another one like this, although there are a couple forum stories about it online from 2004. Usually, they just tape the markings off like you will see on Glock style pistols.
