Sp33dy's Review of Stern Defense SD Mod4 M-Lok 9mm Complete Upper Receiver

Great upper receiver couldn’t pass on a deal when it went on sale. Watched videos and reviews how well Stern Defense 9mm holds up and I was very impressed how sustainable the barrel is. After receiving my upper, I test it at the range and I was at awe. The quality, the smoothness, and precision was worth it.
