Your Questions Answered
What tools do I need to complete these 80% frames?
You will need a hand drill or drill press, a vise to secure the jig, a hammer or mallet, and basic hand tools like files or sandpaper for finishing. The included jigs and drill bits guide the process. Router setups are not required for these polymer frames.
Does this include all parts to build a complete firearm?
No. This is a bundle of two 80% lower receivers (frames) with their completion jigs. You must separately source all other required components: an AR-15 parts kit, buffer system, upper receiver, barrel, etc., for the RL556V3, and a Glock 19 parts kit (LPK & UPK) and slide for the PF940Cv1.
Is the PF940Cv1 compatible with aftermarket Glock slides and magazines?
Yes. The PF940Cv1 is designed for compatibility with standard Glock 19 Gen 1-3 slides, barrels, and internal parts kits. It also accepts all standard Glock 19 magazines and many aftermarket magazines.
