I purchased this type 96 zero trigger jan 10th. It showed up at my door jan 15, not bad. Let me jut say this trigger assembly is outstanding. Its strong, durable, and it dropped right in my utg mk96 other wise know as the shadow ops sniper with no modifications at all. Man the trigger on this is really light and it feels strong. Defiantly worth the money. If you have the money defiantly buy this part. Im an experienced airsoft sniper and tech and this part is a great add on to my list of upgrades.
*No modifications needed to install.(took me about 4 minutes)
*Really smooth trigger.
*No safety switch, because when you install it, it doesn't come with one, but its freaking awesome and i could care less weather it has a safety or not.
* No others at all.
