I have a Vector AK-47 Underfolder. The rifle is excellent and shoots nicely.
Observations/Facts on mine:
1. It was purchased about 3 years ago.
2. It DOES have a chrome-lined bore.
3. It was buit from a Polish parts kit, but the bore looked pristine.
4. The rifle is parkerized.
5. Parked rifles WILL rust if you let them. However, Park is a great base for Duracoat. I will be duracoating that sucker eventually.
6. The Vector rifles DO NOT have a side-mount optics rail.
7. Vector Rifles have a 5 year warranty.
8. My Vector uses a Tapco G2 Single hook trigger group that breaks clean and crisp.
Hope that helps.
