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 barrel installation assembly for installing a barrel onto a receiver of a firearm, the barrel installation assembly comprising:
a barrel nut configured to fasten the barrel to the receiver;
barrel nut spacers configured to be interposed between the barrel nut and the receiver; and
a barrel installation tool for tightening the barrel nut onto the barrel and the receiver, the barrel installation tool comprising:
a head portion configured to removably engage with the barrel nut; and
a barrel nut spacer selection portion including one or more barrel nut spacer selection indicators positioned on the head portion to identify one or more of the barrel nut spacers having a thickness to properly space the barrel nut from the receiver, 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.

2. The assembly of claim 1 , wherein the barrel nut spacer selection portion includes a first barrel nut spacer selection indicator for indicating that a first set of barrel nut spacers is required to be interposed between the barrel nut and the receiver, and
wherein the first set of barrel nut spacers is interposed between the barrel nut and the receiver if the first barrel nut spacer indicator is aligned to a reference point of the receiver when the head portion of the barrel installation tool is engaged with the barrel nut in such a manner that the barrel installation tool is arranged in a first tool position.

3. The assembly of claim 2 , wherein the barrel nut spacer selection portion includes a second barrel nut spacer selection indicator for indicating that a second set of barrel nut spacers is required to be interposed between the barrel nut and the receiver, and
wherein the second set of barrel nut spacers is interposed between the barrel nut and the receiver if the second barrel nut spacer indicator is aligned to the reference point of the receiver while the head portion of the barrel installation tool is engaged with the barrel nut in such a manner that the barrel installation tool is arranged in the first tool position.

4. The assembly of claim 1 , wherein the barrel nut spacer selection portion is circumferentially arranged on the head portion.

5. The assembly of claim 1 , wherein the barrel installation tool includes a barrel nut position indicating portion arranged on the head portion, wherein the barrel nut position indicating portion indicates an amount of rotation of the barrel nut required to properly align the barrel nut with the receiver.

6. The assembly of claim 5 , wherein the barrel nut position indicating portion includes a final position indicator configured to indicate the reference point of the receiver when the barrel nut is properly aligned with the receiver.

7. The assembly of claim 6 , wherein the barrel nut position indicating portion includes a pre-tensioned position indicator configured to indicate the reference point of the receiver when the barrel nut is engaged with the receiver in a first barrel nut position.

8. The assembly of claim 7 , wherein, when the barrel nut is engaged with the receiver in the first barrel nut position, the barrel nut is tightened to the receiver using the tool until the final position indicator is arranged to indicate the reference point of the receiver.

9. The assembly of claim 1 , wherein the barrel nut spacer selection portion comprises more than one barrel nut spacer selection indicator.

10. The assembly of claim 9 , wherein the barrel nut spacers include a first set of barrel nut spacers and a second set of barrel nut spacers, and the barrel nut spacer selection indicators include a first indicator and a second indicator, wherein the first indicator identifies the first set of barrel nut spacers and the second indicator identifies the second set of barrel nut spacers.

11. The assembly of claim 1 , wherein the barrel installation tool further comprises a handle portion extending from the head portion.

12. A barrel installation assembly kit for installing a barrel onto a receiver of a firearm comprising:
a barrel nut configured to fasten the barrel to the receiver;
barrel nut spacers configured to be interposed between the barrel nut and the receiver;
a barrel installation tool for tightening the barrel nut onto the barrel and the receiver, the barrel installation tool comprising:
a head portion configured to removably engage with the barrel nut; and
a barrel nut spacer selection portion including one or more barrel nut spacer selection indicators positioned on the head portion to identify one or more of the barrel nut spacers having a thickness to properly space the barrel nut from the receive, wherein each barrel nut spacer comprises a visual identifier; and

instructions for matching each barrel nut spacer selection indicator to one or more barrel nut spacers having a selected visual identifier.

13. The kit of claim 12 , wherein the barrel installation tool further comprises a handle portion extending from the head portion.

14. The kit of claim 12 , wherein the barrel nut spacer selection portion includes a first barrel nut spacer selection indicator for indicating that a first set of barrel nut spacers is required to be interposed between the barrel nut and the receiver, and
wherein the first set of barrel nut spacers is interposed between the barrel nut and the receiver if the first barrel nut spacer indicator is aligned to a reference point of the receiver when the head portion of the barrel installation tool is engaged with the barrel nut in such a manner that the barrel installation tool is arranged in a first tool position.

15. The kit of claim 14 , wherein the barrel nut spacer selection portion includes a second barrel nut spacer selection indicator for indicating that a second set of barrel nut spacers is required to be interposed between the barrel nut and the receiver, and
wherein the second set of barrel nut spacers is interposed between the barrel nut and the receiver if the second barrel nut spacer indicator is aligned to the reference point of the receiver while the head portion of the barrel installation tool is engaged with the barrel nut in such a manner that the barrel installation tool is arranged in the first tool position.

16. The kit of claim 12 , wherein the barrel nut spacer selection portion is circumferentially arranged on the head portion.

17. The kit of claim 12 , wherein the barrel installation tool includes a barrel nut position indicating portion arranged on the head portion, wherein the barrel nut position indicating portion indicates an amount of rotation of the barrel nut required to properly align the barrel nut with the receiver.

18. The kit of claim 17 , wherein the barrel nut position indicating portion includes a final position indicator configured to indicate the reference point of the receiver when the barrel nut is properly aligned with the receiver.

19. The kit of claim 18 , wherein the barrel nut position indicating portion includes a pre-tensioned position indicator configured to indicate the reference point of the receiver when the barrel nut is engaged with the receiver in a first barrel nut position.

20. The kit of claim 19 wherein, when the barrel nut is engaged with the receiver in the first barrel nut position, the barrel nut is tightened to the receiver using the tool until the final position indicator is arranged to indicate the reference point of the receiver.
