Low quality - Spikes Tactical 7.62x39 Bolt Assembly

There is absolutely NO information anywhere on this 7.62x39 bolt , spikes has nothing on their site . The bolt itself has no markings , weak extractor spring tention and just had a cheap feel to it .

Im extremely disappointed with this bolt and its going back .
I guess spikes is big enough they dont need to care as much , people just buy there stuff (like I just did ) I personally wont ever purchase anything again from them there's just too many other manufacturers that no matter how big they get they keep the quality .
