which one had 45 angle 13-gas port and which 90 angle?

This is an AKM, not an AK-47, the receiver cover is ribbed like the AKM, while the 47 is smooth

As far as I understand, the compensator is from AKM?

It is in fact wrong in many ways. Firstly the bolt carrier moves separately from the bolt in the first 15 mm of run camming the bolt out of battery and then moving back as a whole unit with the bolt. The disconnector isn't shown working, plus you woldn't be able to release the trigger with such speed, also it's a solid part, it isn't pivoting at its extremity. Upon extraction the casing stays attached to the bolt by the rim, until it hits the ejector and is then ejected from the gun. And it's called a sight, rear and front sight not site. Go look up Matt Rittman's video on YouTube if you want an accurate depiction.

You cant releas the trigger so fast (before the Bolt(6) travel). To hold the hammer(5) back you have the disconnector(4). The hammer are pushe down from the boltcarryer and the disconnector snaps over. Than you releas the trigger the back claw release the hammer an the front claw catch it. after another trigger pull the front claw let it go an the weapon fires
