Worst part kit on the market! dont waste your money!!! - KE Arms Gi Lower Parts Kit

So I have put together enough AR's to know how to properly put one together... I ordered these because the CMMG parts kit was backordered at the time. That was a huge mistake. Yes this part kit included everything but they are not functional. First off i went to put the magazine lock/release mechanism in a it kept getting stuck so the mag would not lock without further assistance.... Thinking this was just a 1 off part i went forward putting the FCG in... Trigger/spring in okay... Disconnector/spring in okay... Hammer is where things starting going wrong... I got the pin in place and charged the hammer back and right off its stuck so i played with it a bit to try and figure it out finally figured that out and bypassed it in the mean time... Went to check safety/semi working and the FCG fired in both which is a HUGE no no for me... After that I thought maybe it was just a 1 off all around and scrapped that parts kit luckily i had 2 more... Every single one had the same issues... DO NOT BUY THIS JUNK. Stick with CMMG as 100% of theirs have worked flawlessly for me.
