The Delrin Punch, from LuthAR is a basic plastic punch, which allows you to remove your pins that hold the upper and lower receiver of an AR-15 style rifle together. Delrin is a plastic compound, much like Nylon. I am sure there are other applications as well, but this punch is simple and gets the job done. We use this in our shop at Charlie's Custom Clones, so perhaps you might benefit as well. Many of us have used a screwdriver or similar metal object to knock the pins loose, later to see the scratch marks left.
Charlie's is not your ACE hardware store for gunsmithing tools, but when we see something that works, we bring it to you. LuthAR is a long-trusted name in AR world, and we have no doubt you will be happy with this small purchase.
If you are making a purchase with us, why not add this to your list! At this price, I would not advise this to be your only purchase, otherwise, you will pay more for shipping that this basic tool. Make sure you add more to your cart, and remember, we have a low minimum purchase for reduced or free shipping.
