I was amazed with the initial accuracy. I have a couple other 7.62x39 rifles, an M10X and a VZ 2008. The M10X has a variety of correctable issues and is 'almost 100%' in reliability, while the VZ 2008 has never failed at all. It may be the most reliable semi-automatic rifle I have ever owned, however, it has issues and requires various mounting scenarios for scopes or red dots. This would be a rifle to consider if you want reliability for combat using the provided basic iron sights or even a forward mounted red dot. It's a great home defense rifle with the folding stock and light weight as its greatest attribute. It, however requires proprietary magazines, but does have a last round bolt hold-open feature that no other AK or variant offers. It's probably the most compact 7.62x39 rifle available with a 16" barrel....that works every time!
So why build a 7.62x39? The thought of even better accuracy and I like the platform more than any other rifle. And it's just a thing I can do... LOL
