Prerequisites for Super Safety AR-15 Installation

Stock up on essentials:

  • Super Safety kit (CNC-machined D2 tool steel version recommended for durability)
  • AR-15 lower receiver
  • Mil-spec trigger (pre-cut or modified for Super Safety compatibility)
  • Lubricant (oil for steel components to avoid galling)
  • Gunsmithing tools (punches, soft mallet)

Critical Safety Reminder: If not already removed, disassemble the fire control group (FCG) and safety selector from the AR-15 lower to avoid mishaps.

Step 1: Reinstall the Fire Control Group with Super Safety Components

Assemble the FCG as in a standard AR-15, integrating the Super Safety elements:

  • Install the hammer, trigger, and springs.
  • Add the disconnector and its spring.
Expert Tip for Super Safety Upgrades: Dry-fit the cam and lever prior to full install. The cam should slide effortlessly in the lower’s safety detent hole, and the lever must pivot without resistance in the cam. This confirms no friction issues.

Step 2: Cock the Hammer for Cam Preparation

  • Pull the hammer back to the fully cocked position.

This readies the system for seamless Super Safety AR-15 integration.

Step 3: Insert the Cam from the Left Side

  • From the left of the lower receiver, gently slide in the cam.
  • Position and hold the lever inside the lower, directly above the cam’s insertion path.
  • Engage the cam’s dovetail groove with the lever’s dovetail—they’ll interlock.
  • Orient correctly: Point the cam’s rear crook toward the back of the receiver.
Pitfall to Dodge: Misaligned cam direction can cause failures—verify twice.

Step 4: Install the Detent and Spring

  • Secure the cam while dropping in the detent and spring.
  • Under spring tension, the detent will hold the assembly firm.
Pro Maintenance Advice: Lubricate steel cams with gun oil pre-install to prevent trigger pin galling and extend service life.

Function Testing: Validate Super Safety Before Upper Attachment

Essential for any AR-15 safety upgrade—test without the upper to catch issues early:

  1. Cock the hammer, then advance the lever forward.
  2. Pull the trigger; control the hammer’s drop with your hand or padding.
  3. Maintain trigger pull while recocking the hammer—it engages the disconnector.
  4. With trigger held, retract the lever (mimicking BCG cycle). Trigger resets, freeing the hammer from the disconnector.
  5. Lever fully back: Trigger pull should lock out.
  6. Hold and pull trigger while returning lever forward. Cam release allows trigger to fire—catch the hammer.

Reinspect if tests fail.

Final Assembly and Verification for AR-15 Super Safety

Post-dry test success:

  • Mount the upper receiver.
  • Retest: Fire trigger, cycle BCG rearward. Reset occurs on rear travel; unlock on forward battery.

Range Ready: Clear all dry fires, then live-test with controlled shots.

Common Super Safety AR-15 Installation Fixes

  • No Reset: Inspect disconnector tension or cam seating.
  • Binding Hammer: Re-lube and confirm dovetails.
  • Detent Slip: Ensure spring compression.
