Not satisfied - Zaffiri Precision Glock 19 Gen 3 ZPS.3 RMR Cut Complete Upper Threaded

Aesthetically, the product looks great and fit my lower receiver as advertised. When unboxing, the items front sight post was loose. The spring is not a strong quality. The barrel also has excessive play when sitting in the slide. The upper assembly would continuously jam while chambering a round into the barrel. Overall, a great looking product but not functional or reliable.
