For a semi-auto AR-15, there is no licencing requirement in the US. In other countries, it's quite different, and if you're in a country outside the US, chances are, you need to.

Yes. If it's an assembled rifle lower, you treat it the same as any other private sale of a rifle. If it's a stripped receiver, it's an assembled pistol receiver (or was sold to you as such), or it's an assembled receiver minus the buttstock assembly, you need to act in accordance with the laws of your state for selling a handgun.

Licence requirements are based on the laws WHERE YOU ARE. They vary greatly from one country to another, and one US State to another. And YOU did not tell us where your are. In most of the US, no, a license is not required to purchase a semi-auto AR15. Your spelling of 'licence" may indicate you are not in the US. In Australia, a licence is required to obtain ANY firearm. An AR15 is a Class D firearm, and cannot be owned by the average private citizen.

Yes, and you can own one in any state, although some states have certain restrictions. For example, New York, New Jersey, Massachusettes, Connecticut, and Cook County, Illinois have the 1994 Clinton ban written into their legislature, so AR rifles sold there may only have none or one of the features listed in the ban (flash suppressor, pronounced pistol grip, telescoping buttstock, etc.). In California, rifles not registered prior to the 2000 registration of so-called "assault rifles" must either be featureless (in addition to the features listed in the Clinton ban, California also includes forward grips in theirs), or else must have the "bullet button" installed, which makes it technically a fixed magazine rifle.

First do a full functional clear, eject the mag, rack the bolt/carrier to eject any casing.

Next fully clean the gun.

Check for broken or weak parts in bolt/carrier, gas system, and buffer system.

Use quality ammo.

If it still doesn't then take the gun to someone who knows how to work on ar15 rifles.
