Ar 15 barrel nut

Does any one have a ar15 clamp I could borrow for a couple of hours. I have a barrel nut that I need to remove. And I am trying not to pay the $65 that the gunsmith want. I am in the Plano area. I have the wrench. Just need the clamp. I will pay to borrow it.

Dang 65 is high. I do handguards for 20.

If all you need is the nut removed I will do it free if you are in the Rowlett area this week.
