It appears that either some parts in the trigger group were incorrectly made and/or the receiver is made wrong. The safety lever goes up fine, but there's nothing for it to catch on or block to prevent the gun from firing in the SAFE position.
Pros:
Shoots well, well balanced, handles great
Cons:
WILL STILL FIRE WITH THE SAFETY LEVER IN THE FULL UP (SAFE) POSITION, MAKING THIS A VERY UNSAFE FIREARM!
