Luth ar upper parts kit - Luth-AR A3 Upper Receiver Parts Kit

The kit is good quality and had all of the parts. The port door feels sturdy. Some port doors feel like they’ll bend if you push them too hard. I also ended up losing the roll pin but that was my own fault. I realize it is an extra cost but maybe including an extra pin for people like me would be a nice touch. PSA includes extra detente with their lower kits for that reason. I would definitely buy this kit again.
