The A-R typw rifles use a Pivot Pin secured in the Lower Receiver by a spring-loaded detent to join the Upper and Lower Receiver assemblies. This Pivot Pin Detent Installation Tool is designed to make installation of the Pivot Pin, the Pivot Pin Detent and Detent Spring quick and easy.
HOW TO USE:
These instructions assume that the rifle has been disassembled according to the manufacturer’s instructions and any needed repairs and/or maintenance work has been performed. It is further assumed tha tthe rifle has been reassembled, following the manufacturer’s instructions, to the point where the next step is installation of the Pivot Pin Detent.
Secure the Lower Receiver in a padded vise in a vertical position so the opening at the end of the Pivot Pin Detent hole is pointing “up”.The LONG
arm of the Installation Tool, which has a small through-hole near its end, is inserted from the LEFT side of the receiver into the holes for the Pivot Pin.
Carefully position the Installation Tool so the through-hole is positioned directly over, and in line with , the Detent Spring hole in the right side of
Pass the Detent Spring through the Installation Tool into its seating hole. Next, place the small metal Detent on top of the Detent Spring. Approximately half of the Detent will project out of the hole in the Installation Tool. A 3⁄32" diameter or smaller pouch should be used to press the Detent down into the Detent Spring hole far enough to permit 90° rotation of the of the Installation Tool. Rotating the Installation Tool will hold the Detent securely in place.
Position the small end of the Pivot Pin against, and in perfect alignment with,the end ofthe “long”armofthe InstallationTool.Using both hands and being EXTREMELY CAREFUL,push the Pivot Pin into its hole in the Lower Receiver. At the SAME TIME, you will push the Installation Tool to the left and out of the Lower Receiver.This MUST be done smoothly and quickly to prevent loss of the spring-loaded Pivot Pin Detent. When the Pivot Pin is pushed approximately halfway into the Lower Receiver,it may be necessary to rotate it so the Detent seats into the milled slot in the side of the Pin.The Pivot Pin can now be fully pressed into place in the Lower Receiver. Further reassembly can proceed as required.
IMPORTANT NOTE: ALWAYS wear safety glasses or other appropriate eye protection when working with spring-loaded parts to prevent injury to your eyes.
Reassemble the firearm according to the manufacturer’s instructions. Check for proper functioning using ACTION PROVING DUMMIES. Make sure ALL SAFETY MECHANISMS are fully functional as designed and approved by the manufacturer. If these tests prove satisfactory, test-fire the firearm with live ammunition in a SAFE and APPROPRIATE manner. IMPORTANT! Start the live ammunition tests by first loading an ACTION PROVING DUMMY, then a live round, into the magazine. Only after several tests have been conducted in this manner should additional rounds be placed in the magazine and fired.
This tool is simple but very useful..
1. Simply push the pin in from the opposite side that the pivot pin goes in from.
2. Line up the hole in the pin with the hole in the receiver.
3. Place the pivot pin spring in the hole.
4. Place the detent in the hole.
5. Use a punch (or modified pin included) to push the pivot pin detent and spring down while you rotate the pin. (also included, modified pin for removal)
6. Use the pivot pin to push the 1/4" x 2" pin out. Doing this, the 1/4" pin will hold the detent down, so it will not go flying across the room.
I will email or include detailed illustrated instructions in the package if you don't have an email..
