Full Auto Glock Switch & Drop in Auto Sear Keychain: What You Need to Know

Understanding Conversion Devices

The topic of Full Auto Glock Switch and Drop in Auto Sear Keychain devices generates significant discussion in firearms circles.

What is a Full Auto Glock Switch?

A Full Auto Glock Switch (also called a “Gun switch,” “auto sear,” or “giggle switch”) is a small device that converts semi-automatic Glock pistols into fully automatic machine pistols. It replaces the slide’s rear cover plate and manipulates the trigger bar to bypass the semi-automatic firing mechanism, enabling continuous fire with a single trigger pull. This results in a rate of fire exceeding 1,200 rounds per minute, emptying a standard magazine in seconds 146.

Full Auto Glock Switch Installation

1. Disassembly: Remove the Glock’s slide and factory backplate using a punch tool.
2. Replacement: Align the switch with the slide rails and insert it into the rear housing, replacing the original backplate.
3. Trigger Engagement: The switch’s internal arm interfaces with the trigger bar, altering its reset function.
4. Reassembly: Reattach the slide and cycle the action to test functionality.

Key Notes:

• Requires no permanent modification to the pistol.
• Installation takes <5 minutes with basic tools.
• May require filing for proper fitment on aftermarket slides.

AR Auto Sears: Drop-in Auto Sear (DIAS) & Swift Links

Types and Mechanisms

1. Drop in Auto Sear (DIAS):
   • A self-contained unit inserted into an AR-15’s fire control group (FCG). It interacts with the bolt carrier group to enable automatic firing without requiring a third pin hole. DIAS devices often require M-16-compatible components (e.g., hammer, bolt carrier).
2. Swift Links (Yankee Boogle):
   • A 3D-printed variant popularized by DIY firearm communities. Designed by Dugan Ashley in 2016, it mimics the function of traditional auto sears and works with mil-spec AR-15 bolt carriers. Unlike DIAS, it requires no milling but is fragile and incompatible with commercial lowers (e.g., Ruger, Colt).
3. Lightning Links:
   • A pre-1986 design for Colt AR-15s that converts the rifle to full-auto-only fire. It requires specific bolt carriers and receiver modifications, making it less practical for modern builds

AR Auto Sears Installation

Drop in Auto Sear (DIAS)

1. Lower Receiver Access: Remove the AR-15’s trigger group pins to access the fire control cavity.
2. Insertion: Place the DIAS into the trigger pocket, aligning it with the hammer and disconnector.
3. Modifications: Requires an M-16-style bolt carrier and often a drilled third pin hole (depending on design).
4. Testing: Cycle the action to ensure the sear engages the bolt carrier’s auto trip ledge.

Swift Links/Yankee Boogle

1. Disconnector Replacement: Remove the factory disconnector from the trigger group.
2. Installation: Insert the 3D-printed Swift Link into the disconnector spring channel.
3. Function Check: The link holds the hammer in a “bump fire” position during cycling.

Lightning Links

1. Bolt Compatibility: Install a full-auto bolt carrier with an auto sear trip notch.
2. Trigger Group: Replace the semi-auto hammer with an M-16 hammer.
3. Link Placement: Insert the lightning link into the trigger pocket, secured by the hammer pin.

Key Notes:

• DIAS/Swift Links require no permanent receiver modifications.
• Lightning Links demand milling for proper sear engagement.
