Seeking Advice on Building a 2011 Frame 80 Percent

I’ve recently dived into the world of DIY firearms and I’m particularly interested in building a 2011 frame from an 80 percent lower receiver. However, I’m hitting a few roadblocks in the process and could really use some advice from those who have gone through this before.

What I Have So Far

I’ve purchased an 80 percent lower and have all the necessary tools, including a drill press and end mill. I’ve watched a ton of videos online, but I still feel a bit overwhelmed. Here are the main areas where I’m seeking guidance:

  • Machining Process: I know the basics but would love to hear more about the common pitfalls to avoid when machining the frame. Any specific tips?
  • Tools Recommendations: Are there any additional tools or jigs that you would recommend for accuracy and ease of building?
  • Regulations and Compliance: I want to make sure I’m following all laws regarding building my own firearm. What resources or steps do you recommend to ensure I’m compliant?

My Concerns

I’m also concerned about the finish. I want my build to not only function well but also look great. Do you have suggestions for the best finishes to use? Also, if you’ve painted or cerakoted your builds, what products have you used?

Hey everyone! I’m working on a 2011 frame 80% build and wondering about the current laws regarding 80 percent lowers. Are there any state-specific regulations I should be aware of?

Great question! Laws can vary widely by state. For example, California has specific restrictions that others don’t. Make sure to check your state legislation!

4

In most places, as long as you’re not selling the firearm, you’re usually in the clear. Still, double-check your local laws, especially since federal guidelines can change too.

5

Exactly! That’s one of the key points. Just remember, the moment you transfer it, you might trigger different legal requirements. So build wisely!

I’ve had a few friends get into hot water because they didn’t check their local laws. Some states are stricter than others, so it’s crucial to know before you build!

7

Definitely! It’s always good to err on the side of caution. Does anyone have resources on where to find reliable legal information about this?

8

You can try the ATF’s website for federal guidelines, but also state gun rights groups. They often have updated info on state-specific laws.

The best advice is to keep your build and use it for personal purposes only. It’s amazing how much the laws differ state to state!

Exactly! A friend in New York had issues with what we consider a non-issue here in Texas. It’s wild to think about!

What about storage laws for these lowers? Do state laws cover how they’re stored once completed?

That’s a good point! Generally, secure storage is recommended, especially if you live in a state with strict firearm laws. Better safe than sorry!

13

So much to keep track of! I feel like I need a law degree just to build my own gun. Anyone else feel that way? Maybe just keep it simple.

14

Right?! Sometimes I think the laws are designed to confuse us. Maybe we need a law-friendly app to make things clear!

15

Just remember, on top of all these laws, building and customizing your own firearm can be really rewarding once you get past the legal mumbo jumbo!

I’m really excited to start my 2011 build too! One thing I’ve read is that proper tools make a huge difference. Invest in a good torque wrench and a punch set! What tools do you already have?

17

Absolutely! A solid vice and some good clamps can help with assembly significantly. I also recommend getting a dedicated lower receiver vise block—it makes a world of difference when installing parts.

18

Has anyone found certain brands of parts that work particularly well with 80 percent lowers? I’m leaning toward some higher-end components for better precision.

19

For uppers, I’ve had great luck with Aero Precision and Palmetto State Armory. Their parts are often compatible and pretty reliable!

I second what Kathleen mentioned! Also, don’t forget to check for compatibility with your lower part kits. Some kits can be overly specific.
