Not sure what to make of it - FailZero AR15 Bolt Carrier Group (BCG), No Hammer

I got the cool looking black one.. Looks very nice on her surface packaged well exterior coating looks very nice.. it wasn’t until I started looking more closely that I found things that I’d say I wouldn’t expect. Staking is there but it almost looks like the material pushed toward the bolt is bound to break off as it is separated on one side of the staking from the original material being pushed see. Also closer look of the firing pins shows some unusual markings I assume tooling. I can’t post pictures I have plenty pictures speak a thousand words. Hopefully she runs well I haven’t been able to get out and fire this thing yet but first impressions no so impressed. 3 stars for now we will see after I shoot it if she keeps all three.
