MOD9V3 is a modular 9mm Luger semi-automatic 3D printed Pistol Caliber Carbine (PCC). Its defining differences from the MOD9V2 are the addition of an extractor to the bolt, ambi mag release, and ease of configuring and customizing the 3D printable files for the endusers build parts and choosen graphics, through the use of Openscad customizer. The MOD9V3 maintains the large compatibilty of build parts as the MOD9V2, except the bolt becaase of the more complex design. Supporting documentation for building the MOD9V3 is limited, but assembly is simlar to the MOD9V2, minus the portions relating to bolt assembly.

Congratulations on choosing the MOD9V3. We hope you enjoy it, and spread the joy of this hobby through this design.

It is not recomend to build the MOD9V3 firearm if you have no expereince building 3D printed firearms. The MOD9V3 requires more work to assemble because of the bolt with extractor, and if you choose to make the bolt yourself you will require additional tools and some knowledge, compared to the V2, to make the bolt to spec. Bolts, firing pins, and hardware parts kits are avilable from memebers in the WF&GCI online community, if you choose to go that route.

MOD9V3 is constructed using 3D printed components, easily-obtainable hardware store fasteners, as well as a few firearm components (G17, SW9VE, & RP9 barrels, Glock magazine, AK-47 recoil spring, and AR-15 FCG), or alternatively use none firearms components (ECM barrel, 3D printed Glock magazine, compression spring as a recoil spring, and 3D printed AR-15 FCG). Note that the bolt on the V3 has an extractor, and therefore the bolt is more rigourous by oneself if they do not have the appropriate tools and knolwdge. Their is a DIYable bolt in open beta, but no additional notes at the time of writing this on it. The MOD9V3 was developed to be the most advanced and capable 3D printed semi-automatic 9mm Luger Pistol Calber Carbine(PCC) at the time it was developed and released, in late 2020. The MOD9V3 is a modular platform and that comes with several different parts, such as multiple barrel retainers and handguards, braces, foregrips, grips, magwells, upper receivers, stocks, and logo and texture options.
