Polymer80 Jig Tool Set and Accessories
Modulus Arms has been a leader in 80 lower jig development and router-based tooling since 2014. The Polymer80 jig tool set is a pistol-frame accessory category separate from rifle 80 lower jig systems. Searchers often land on rifle jig content because both categories use "80" terminology.
Quick answer: Modulus sells a Polymer80 jig tool set with drill bits and a carbide burr, plus frame-specific Polymer80 jigs for PF940V2 and PF940C blanks. These products live in the pistol jig category—not the rifle /80-lower-jigs path. Match the jig SKU to your frame model before purchasing accessories.
Pistol Jigs vs Rifle 80 Lower Jigs
The first compatibility layer is product category:
| Category | Modulus path | Primary use |
|---|---|---|
| Rifle 80 lower jigs | /80-lower-jigs |
AR-15, AR-9, .308, and related rifle receiver fixtures |
| Pistol frame jigs | /80-pistol-jigs/ |
Polymer80 and other pistol frame blank fixtures |
Polymer80 products belong to the pistol jig category. Router Jig Extreme, Router Jig Pro, and Easy Jig families are rifle-path products. Do not assume tooling interchangeability across categories.
Polymer80 Jig Tool Set Overview
Modulus lists the Polymer 80 Jig Tool Set as an accessory product for Polymer80 frame workflows. Product-page component categories include:
| Component category | Role at buyer level |
|---|---|
| Drill bits | Frame pin and tooling hole categories referenced on product page |
| Carbide burr | Cutting accessory category for frame work |
The tool set is an accessory SKU—not a complete jig fixture. Buyers still need the frame-specific jig product matching their blank.
This guide describes product categories from live listings. It does not reproduce operational sequences from product tooling lists.
Frame-Specific Polymer80 Jigs
Modulus sells separate jig products aligned to Polymer80 frame families:
| Product | Frame alignment |
|---|---|
| Polymer80 Jig for PF940V2 | Full-size PF940V2 frame blanks |
| Polymer80 Jig for PF940C | Compact PF940C frame blanks |
Product pages describe these jigs as one-time-use thermoplastic fixtures with thick wall construction language. Treat one-time-use language as a product lifecycle category—plan accessory and jig purchases accordingly.
Frame model matching is the critical compatibility check. PF940V2 and PF940C jigs are not interchangeable without verifying product-page fit language.
How the Tool Set Relates to Frame Jigs
Think of the purchase in two layers:
- Frame-specific jig — fixture matched to PF940V2 or PF940C blank family
- Tool set accessory — drill bits and burr bundle listed as companion tooling
| Buyer question | Where to verify |
|---|---|
| Which jig fits my frame? | PF940V2 vs PF940C product pages |
| Do I need the tool set separately? | Tool set listing + jig listing component notes |
| Is this a router jig? | No — pistol frame category, not rifle router jig path |
For rifle router jig tooling paths, see 80 Lower Jig Tool Kits and SpeedMill Explained.
Other Products in the Pistol Jig Category
The /80-pistol-jigs/ category may also list non-Polymer80 pistol jig products such as multi-platform pistol jig starter kits from other manufacturers. When comparing listings:
- Read frame compatibility labels first
- Separate Polymer80 SKUs from other pistol jig families
- Do not assume rifle multi-platform jig rules apply to pistol frames
Replacement and Accessory Support
Polymer80 accessories appear in Modulus replacement documentation alongside rifle jig families. See 80 Lower Jig Replacement Parts Guide for the category map that includes Polymer80 accessory paths.
Replacement shopping rules:
| Rule | Why |
|---|---|
| Match frame model | PF940V2 and PF940C are distinct SKUs |
| Match product generation | Jig and accessory listings change over time |
| Verify live inventory | Category inventory shifts |
Verification Checklist
Before purchasing Polymer80 jig products:
- Confirm pistol jig category—not rifle
/80-lower-jigs - Identify frame model: PF940V2 full-size vs PF940C compact
- Select matching frame-specific jig SKU
- Add Polymer 80 Jig Tool Set if not bundled on jig page
- Read product-page compatibility and disclaimer blocks
- Contact support with frame SKU if listing language is unclear

FAQ
What is the Polymer80 jig tool set?
It is a Modulus accessory listing with drill bits and a carbide burr for Polymer80 frame workflows. It complements frame-specific Polymer80 jigs—it is not a standalone jig fixture.
Which Polymer80 jig fits my frame?
PF940V2 blanks align with the PF940V2 jig product. PF940C blanks align with the PF940C jig product. Verify on live product pages.
Can I use Polymer80 tooling with an AR-15 80 lower jig?
No. Polymer80 products are pistol frame category items. Rifle 80 lower jigs use separate fixture and tooling ecosystems.
Are Polymer80 jigs reusable?
Product pages describe one-time-use thermoplastic jig language. Treat that as a product lifecycle category when planning purchases.
