Will break at the lugs where takedown pins go in! - American Tactical Imports AR-15 Stripped Poly Hybrid Upper Receiver

I have an AR15 pistol with this brand upper and lower that a buddy gave me. First the front lug got loose, with the aluminum internal that's inside the polymer started rattling. Make a long story short, my AR pistol broke on half when the upper broke off from the lower at the lugs as the entire bolt just slid out with the round it had chambered after it had already gone bang. As expected, ATI didn't want to give me the time of day and back their brand up because I was not the original purchaser. The lower is still intact, so im just transferring the barrel handguard and forward assist to a new billet upper & will run it with the still intact ATI lower on the AR. If the lower eventually breaks, at least it was free. But I wouldn't pay to buy their brand of polymer ARs, especially if they only wanna back up their product if you are the original buyer.

Zero stars if I could
