After the handguard is eliminated, if relevant, you might must take away any entrance handguard retention rings. These rings safe the handguard to the barrel nut or different parts.
Loosening the Barrel Nut
The barrel nut is a crucial part that holds the barrel in place. Find it on the higher receiver and use your armorer’s wrench to loosen it. Place the wrench on the barrel nut, making certain it engages correctly. Apply regular, managed strain. You would possibly want a big quantity of power to interrupt the nut free, particularly if it has been torqued correctly through the earlier meeting. For those who discover the nut is extraordinarily troublesome to take away, you would possibly want to use penetrating oil and let it sit for some time.
Extracting the Barrel
As soon as the barrel nut is totally eliminated, you possibly can take away the barrel from the higher receiver. Pay attention to any indexing marks, as they might be wanted for reassembly. Rigorously pull the barrel ahead from the higher receiver. It could require a little bit of a wiggle, nevertheless it ought to slide out comparatively simply.
Working with the Fuel Tube and Fuel Block
For those who’re changing the barrel, you’ll seemingly must take away the fuel tube and fuel block. The fuel block sits on the barrel and directs fuel again into the fuel system to cycle the motion. Loosen the set screws or take away the retaining pins that safe the fuel block to the barrel. Slide the fuel block off the barrel.
Then, gently take away the fuel tube. Watch out to not bend or harm it throughout elimination.
Dealing with the Bolt Service Group
The bolt provider group (BCG) is the center of the AR-15’s working system. Earlier than disassembling additional, take away the charging deal with. Then, rigorously pull the charging deal with again and take away it from the receiver.

Tightening the Barrel Nut
Subsequent, substitute the barrel nut. Place the barrel nut over the barrel. Use the armorer’s wrench to tighten the barrel nut. Consult with the producer’s specs or the final tips for torque values.
Correctly torque the barrel nut. The barrel nut must be torqued accurately to make sure barrel stability and accuracy. Utilizing a torque wrench, tighten the barrel nut to the desired torque setting.
Fuel Tube Alignment
For those who eliminated the fuel block, be sure you realign the fuel tube accurately. While you reattach the fuel tube, guarantee it’s correctly aligned with the fuel block and the fuel port on the barrel. Safe the fuel block with the set screws or retaining pins.
Remaining Checks
After reassembly is full, carry out a closing security test. Double-check to make sure there are not any obstructions within the barrel and that the rifle capabilities accurately.
Troubleshooting Frequent Points
Barrel Nut Issues
Even with essentially the most cautious method, issues can come up. Listed below are among the frequent points you would possibly encounter.
If the barrel nut is extraordinarily troublesome to take away, apply penetrating oil and permit it to take a seat for some time.
