AKU-94 Parts IdentificationPISTOL GRIP FITTING

The tang at the rear of the pistol grip will fit into the slot at the bottom of the trunnion. This tang is purposely oversized. Due to different manufacturing tolerances/materials on nearly every type of AK tested, this tang will have to be fitted to your particular rifle.

Test fit by inserting this tang into slot at base of trunnion, sliding hand guard retainer onto front of pistol grip and closing retainer locking lever. If you have a tight fit, set the pistol grip aside and proceed to the next assembly step. If tang will not fit into slot or the locking lever will not close, proceed to the next assembly step. If the tang will not fit into slot or the locking lever will not close, proceed to step A below.

STEP A: With sandpaper or a flat file CAREFULLY REMOVE some material from top of tang. CHECK FIT. CAUTION: Be careful not to remove too much material as this will result in a loose fit.

STEP B: Repeat step A until you have a TIGHT FIT. Detach pistol grip, set aside and proceed to the next assembly step.

HAMMER RELEASE/TRIGGER WIRE ASSEMBLY

Important: The trigger wire is specifically formed to ensure proper operation. DO NOT ALTER ITS SHAPE.

  1. From above receiver: slide the trigger wire (with wire against right wall of receiver) past magazine well through slot below trunnion block.
  2. Insert the conversion kit�s disconnector with original disconnector spring into position on hammer release, ensuring that the spring end is seated in the recessed hole at rear of hammer release.
  3. Insert hammer release/disconnector into position formerly occupied by the trigger.
  4. Holding new hammer release/disconnect in place, push trigger pivot pin from left side through to right.

HAMMER ASSEMBLY

  1. Duplicating its orientation on the original hammer, install the original coil hammer spring onto conversion kit�s hammer.
  2. Place this assembly into position, ensuring that the coil spring tails are in proper position pressing down on trailing arms of hammer release.
  3. Ensuring that the trigger wire is against right receiver wall and in place, push hammer pivot pin from left side through to right.
  4. Through the magazine well, reinsert the original hammer/trigger pin retaining spring back into its original position, ensuring that it engages the retaining grooves on both the hammer and trigger pins.

FRONT SIGHT INSTALLATION

  1. Insert cylindrical plug into rifle�s sight hood with hole vertical.
  2. Seat the conversion kit�s front sight block onto top of sight hood.
  3. Insert sight bolt through top of sight block and loosely screw down with a �" Allen wrench. If necessary adjust front sight slide until sight block is absolutely vertical viewed from front. Tighten down sight bolt.
  4. Using a 1/16" Allen wrench tighten set screw to lock sight bolt.
  5. Insert original front sight post into threaded recess of front sight bolt and tighten down, setting sight post height to your preference.

REAR SIGHT INSTALLATION

  1. Tap the hole originally covered by the rear sight leaf at top of rear sight block with an 8-32 threading tap.
  2. Press new rear sight into position, align holes and drive roll pin through to secure front end of sight.
  3. Insert locking screw into vertical hole at back of sight and tighten with 3/32 Allen wrench into hole tapped in step one.

TRIGGER/PISTOL GRIP INSTALLATION

At this point the loose end of the trigger wire should be protruding under the barrel from the slot at the bottom of the trunnion.

  1. Slide loose end of trigger wire fully through slot at rear right of the pistol grip.
  2. Allow pistol grip to hang from trigger wire and secure hooked end of trigger wire through hole at rear top of trigger.
  3. Drop trigger into its recess in pistol grip.
  4. Slide tang of pistol grip into trunnion slot and push back until seated.
  5. Capture other end of pistol grip with lower hand guard retainer and secure by locking back the small retainer lever.
  6. Line up holes in trigger and pistol grip and insert trigger pivot pin from right side.

TESTING FIRE CONTROL GROUP INSTALLATION

  1. With thumb, cock back hammer to ready position. Squeeze trigger.
  2. Repeat step 1 several times, until satisfied that the firearm is operating properly.

The trigger should snap back to its ready position each time it is pulled. If this is not the case review your assembly steps, paying particular attention to possible binding of the trigger wire.

GAS TUBE ASSEMBLY

  1. Remove wooden gas tube cover by rotating until it disengages from tube. (Note: some wooden covers are very tight. You may have to clamp the block end of the tube securely in a vise to apply enough torque to rotate the wooden part loose.)
  2. Rotate your new gas tube cover onto gas tube.

FINAL ASSEMBLY AND TEST

  1. Install GAS TUBE and lock down lever. Install BOLT/CARRIER and RECOIL SPRING assemblies. Install CHEEKPIECE/TOP COVER and STOCK. Screw down stock screw.
  2. Position halves of FOREGRIP around barrel/gas block and tighten screws securely. (Do not over-tighten.)
  3. Pull back charging handle. Engage safety. Test safety by squeezing trigger. Disengage safety. Squeeze trigger. Repeat until satisfied.
