- Hidden Consumables: Cutting fluid, sandpaper, and finishes (cerakote, bluing) are recurring costs.
- Mistake Premium: A ruined frame or incorrectly fitted slide results in full replacement costs, not just repair.
Budget an additional 30–50% above the frame’s sticker price for these associated expenses to avoid project delays.
Hidden Costs: Tools, Jigs, and Finishing Supplies
Navigating the budget for an 80% frame build requires more than just the receiver’s price tag. While the raw frame itself is affordable, the true cost emerges from the completion kit and tooling, which can easily double your initial outlay. A quality jig, drill press, and specialized router bits are non-negotiable investments that prevent costly errors. You must also factor in finishing expenses like cerakote or anodizing, plus compliance components such as a serialized fire control group. Always overestimate your budget by 30% to cover unexpected part tolerances or tool replacements. To keep costs lean:
- Source jigs and tooling from community resale groups.
- Opt for raw aluminum over pre-finished blanks.
- Skip high-end triggers on your first build.
A solid plan here turns a hobby project into a precision tool without financial regret.
