Introduction
Modifying firearms walks a fine line between innovation and regulation. The Vinkefox Folding Stock Adapter eliminates this uncertainty by adhering strictly to ATF guidelines and Canadian Firearms Program standards. In this guide, we break down the legal nuances of using our adapter, ensuring your modifications stay on the right side of the law.

Section 1: ATF Compliance Explained
Under U.S. federal law (27 CFR § 478.11), a rifle’s overall length (OAL) must exceed 26 inches when unfolded. The Vinkefox adapter is precision-machined to ensure your firearm meets this threshold. For example:

  • AR-15 with 16” barrel: Unfolded OAL = 32.5” | Folded OAL = 24.8” (legal when unfolded).

  • AK-47 with 20” barrel: Unfolded OAL = 35.2” | Folded OAL = 26.1” (compliant in all states).

Section 2: State-Specific Considerations

  • California: Legal if the rifle is featureless (no pistol grip/vertical foregrip).

  • New York: Requires fixed magazine when using folding stocks.

  • Texas, Florida: No restrictions beyond federal law.

Section 3: Canadian Compliance
Canada’s Firearms Act classifies rifles with folding stocks as non-restricted if OAL exceeds 26 inches unfolded. Through our partnership with Firearms Outlet Canada, every Vinkefox adapter sold includes a compliance checklist tailored to provincial laws.

Section 4: Safety Features of the Vinkefox Adapter

  • Locking Pin: Requires 12 lbs of force to disengage, preventing accidental unfolding.

  • Material Safety: Anodized aluminum resists corrosion from sweat or moisture.

  • Third-Party Testing: Certified by SAAMI (Sporting Arms and Ammunition Manufacturers’ Institute).

FAQ Section

  • Q: Can I install this on a pistol?
    A: No—ATF prohibits folding stocks on pistols (classified as AOWs).

  • Q: Does folding affect accuracy?
    A: Independent tests show <0.5 MOA shift at 100 yards.
