Good kit for the small pieces but.... - Zaffiri Precision Glock 19 Gen 5 Upper Parts Kit

This is the cheapest way to get all the upper parts for a Glock 19 Gen 5 (minus the slide itself) but that being said the recoil spring is not to OEM standard. I shot less than 500 rounds and then the black end cap gave out and failed and then parts all over the place. I do recommend getting this kit then just getting an OEM recoil spring from the glock store because this one was well under par. 4 star for the rest of the pieces. 1 star for the recoil spring.
