MOD9V2 is a modular 9mm Luger semi-automatic 3D printed and DIYable Pistol Caliber Carbine (PCC). Its defining differences from the MOD9V1 are the several internal improvements to the design and additional accesories in the months following the MOD9V1's release. MOD9V2 supports much more various parts to build with than the V1. MOD9V2 also has the most thorough supporting documentation of the firearms released by WF&GCI, and has its own dedicated assembly video series.

Congratulations on choosing the MOD9V2. We hope you enjoy it, and spread the joy of this hobby through this design.

The MOD9V2 is the 3D printable and DIYable firearm we recommend to build if you starting out with building 3D printed firearms and/or have not built a 3D printed firearm before, because the MOD9V3 requires more work to assemble on your because of the bolt with extractor. Bolts, firing pins, and hardware parts kits are avilable from memebers in the WF&GCI online community, if you choose to go that route.

The MOD9V2 is constructed using 3D printed components, easily-obtainable hardware store fasteners, a DIY-style steel bolt, 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). The MOD9V2 was developed to be the most advanced and capable 3D printed and DIYable semi-automatic 9mm Luger Pistol Calber Carbine(PCC) at the time it was developed and released, in Mid 2020. The MOD9V2 is a modular platform that comes with several different parts, such as multiple barrel retainers and handguards, braces, foregrips, grips, magwells, upper receivers, stocks, and most importantly has a dedicated community continually designing more parts, upgrades, and accessories.
