What are the best pins for a polymer rifle stock?
Roll Pins ($13): I bought a monster pack since I’m always losing them in AR builds. This one will definitely have several 1/8″ roll pins. Epoxy ($6): I went with a plastic bonding epoxy since you want it to stay to the polymer rifle stock. I’ll be pinning my Bravo B5 stock ($60) but this should translate to any adjustable polymer stock.
What is ACR in azure?
Azure Container Registry (ACR) allows us to store Docker Container images for Docker Swarm, Docker and Kubernetes access them from anywhere using a secure password or Azure AD credentials. ACR comes in three pricing plans based on storage and security features.
What can I do with ACR?
I can also use ACR to pull \ download my images to my machine or a container host from any machine that has an internet connection.
Can you pin a collapsible stock to the assault weapons ban?
Learn how to easily pin a collapsible stock to satisfy the Assault Weapons Ban (AWB) criteria with a drill, roll pin, and epoxy. Note the disclaimer that this is for educational purposes only and that you should double-check all laws surrounding this.

Tools Needed
Drill & Bits: Hopefully you have something at home or can borrow someones since you’ll only need it for a second. I went with a 1/8″ drill bit but as long as you can match up the bit to the roll pin, you’re fine.
Pinning a Collapsible Stock
I’ll be pinning my Bravo B5 stock ($60) but this should translate to any adjustable polymer stock. I like the B5 since it’s really light and has that angle that gives me a really good cheekweld.
Alternatives to Pinning Your Stock
Something new has come along…the Stock Lok ($35). It swaps out the adjusting pin in your stock so that it becomes fixed. Perfect if you don’t want to pin after reading this tutorial.
