Every Patriot who chooses MGB for their Freedom parts will receive a code shipped with their purchase for a Free Self-Paced Frame Assembly Course at Freedom Crew University.
 
If you decide not to choose the MGB store, verify your parts from other sellers - Genuine G20 Firing Pins will have 3 hash marks and be stamped 4557. Additionally, it is imperative to use the correct extractor with the right bearing. G20 (10mm) extractor is marked 1909. and will use the Olive LCI bearing 3442. Finally, please prioritize safety and do not attempt PF45 builds with the Taiwan junk parts on Ebay. 
 
Whether you choose the MGB store to be your Freedom Parts provider or not - we are here to help with any questions.
 
The internet is flooded with 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.
 
MGB Guarantee:
I individually inspect each package for first time quality. When you buy from MGB, you are buying Authentic Genuine Glock® OEM products.
*Note: I will assemble the extractor depressor plunger with Loaded Chamber Indicator Bearing (Olive) for you. Additionally, I will assemble the firing pin components ready for you to drop in.
