Abstract

A barrel installation assembly is used for easily installing a barrel onto a receiver of a firearm with proper torque and alignment. The barrel installation assembly includes a barrel nut, barrel nut spacers, and a barrel installation tool. The barrel nut is configured to fasten the barrel to the receiver. The barrel nut spacers are configured to be interposed between the barrel nut and the receiver when the barrel is fastened thereto. The barrel installation tool includes a head portion configured to removably engage with the barrel nut, and a handle portion extending from the head portion.

First claim

What is claimed is:

1. A method of installing a barrel to a receiver of a firearm, the method comprising:
inserting the barrel into the receiver;
fastening the barrel to the receiver with a barrel nut;
engaging a barrel installation tool with the barrel nut so that the barrel installation tool is in a first tool position;
identifying one or more barrel nut spacers via one or more barrel nut spacer selection indicators of the barrel installation tool, wherein each barrel nut spacer selection indicator comprises a visual identifier that matches a visual identifier on at least one of the barrel nut spacers;
installing the identified one or more barrel nut spacers between the barrel and the barrel nut; and
tightening the barrel nut using the barrel installation tool until the barrel installation tool is in a second tool position in which a final position indicator of the barrel installation tool is aligned with a reference point of the receiver to provide a first amount of torque between the barrel nut and the receiver and to align the barrel nut with the receiver.

2. The method of claim 1 , further comprising determining that the barrel nut is in a first barrel nut position before tightening the barrel nut using the barrel installation tool until the barrel installation tool is in the second tool position.

3. The method of claim 2 , wherein, when the barrel nut is in the first barrel nut position, a pre-tensioned position indicator of the barrel installation tool is aligned with the reference point of the receiver as the barrel installation tool is in the first tool position.

4. The method of claim 1 ,
wherein the one or more barrel nut spacers are selected so that the barrel nut is in a first position when the barrel installation tool is engaged with the barrel nut in the first tool position after fastening the barrel to the receiver with the barrel nut.

5. The method of claim 1 , wherein identifying the one or more barrel nut spacers comprises identifying the one or more barrel nut spacer selection indicators being aligned with the reference point of the receiver when the barrel installation tool is in the first tool position.

6. The method of claim 1 , wherein installing the identified one or more barrel nut spacers comprises:
inserting the identified one or more barrel nut spacers over the barrel;
inserting the barrel nut over the barrel with the identified one or more barrel nut spacers interposed between the barrel nut and the receiver; and
screwing the barrel nut onto the receiver.

7. The method of claim 6 further comprising:
loosening the barrel nut from the receiver; and
removing the barrel nut from the receiver.

8. A method of installing a barrel to a receiver of a firearm, the method comprising:
inserting the barrel into the receiver;
fastening the barrel to the receiver with a barrel nut;
engaging a barrel installation tool with the barrel nut so that the barrel installation tool is in a first tool position;
identifying one or more barrel nut spacers via one or more barrel nut spacer selection indicators of the barrel installation tool by matching each barrel nut spacer selection indicator to a visual identifier on at least one of the barrel nut spacers via one or more corresponding instructions;
installing the identified one or more barrel nut spacers between the barrel and the barrel nut; and
tightening the barrel nut using the barrel installation tool until the barrel installation tool is in a second tool position in which a final position indicator of the barrel installation tool is aligned with a reference point of the receiver to provide a first amount of torque between the barrel nut and the receiver and to align the barrel nut to the receiver.

9. The method of claim 8 , further comprising determining that the barrel nut is in a first barrel nut position before tightening the barrel nut using the barrel installation tool until the barrel installation tool is in the second tool position.

10. The method of claim 9 , wherein, when the barrel nut is in the first barrel nut position, a pre-tensioned position indicator of the barrel installation tool is aligned with the reference point of the receiver as the barrel installation tool is in the first tool position.

11. The method of claim 8 , wherein the one or more barrel nut spacers are selected so that the barrel nut is in a first position when the barrel installation tool is engaged with the barrel nut in the first tool position after fastening the barrel to the receiver with the barrel nut.

12. The method of claim 8 , wherein identifying the one or more barrel nut spacers comprises identifying the one or more barrel nut spacer selection indicators being aligned with the reference point of the receiver when the barrel installation tool is in the first tool position.

13. The method of claim 8 , wherein installing the identified one or more barrel nut spacers comprises:
inserting the identified one or more barrel nut spacers over the barrel;
inserting the barrel nut over the barrel with the identified one or more barrel nut spacers interposed between the barrel nut and the receiver; and
screwing the barrel nut onto the receiver.

14. The method of claim 8 further comprising:
loosening the barrel nut from the receiver; and
removing the barrel nut from the receiver.
