With the release of the LCT Airsoft PP-19-01 AEG, or the Vityaz AEG, we now have a fully production model of the Vityaz for airsoft as compared to custom projects made by airsoft players before. But how different it is from the LCKS74UN (or AKS74U) apart from using 9mm magazines? LCT Airsoft made a video to show that:

1. The length of stock is the same as LCKS74UN AEG.
2. The shape hook of stock is similar to PP-19 AEG, and the function as real steel.
3. The receiver and top cover is different from LCKS74UN AEG.
4. The bolt carrier is different from LCKS74UN AEG.
