Genuine Glock® 19 Upper Parts Kit OEM Gen 3 from Marine Gun Builder. Never gamble with your safety - choose authenticity, choose reliability, choose Glock OEM parts that have 40 years of proven excellence in dependability, performance, and safety!

Don't get swindled on Ebay by sellers who swap out parts to poorly made clones and pass them off as Authentic OEM Glock® factory parts. Ebay is flooded with listings for OEM kits that contain counterfeit firing pins, fake extractors, and poorly made springs. These fraudulent parts are unbranded and unsafe. OEM Glock parts are required to pass rigorous manufacturer Quality Controls with extensive test firing and proper safety protocols. The failure rate in our build community using imitation parts is staggering. Read my full Blog post "Glock OEM vs. Knockoffs" to ensure you are buying genuine factory Glock® OEM parts. Don't get duped!!
