ScopedIn

ScopedIn is hosting an AR-15 build party for members of the Sunnyvale Rod & Gun Club. This is a great way to learn how to build up an AR-15 lower. Mike Zimmers from ScopedIn will furnish the necessary tools, the workspace and his (basic) knowledge in how to assemble an AR-15 lower receiver. This will also be an opportunity to view some of the premium AR-15 components available on the market.

You must supply:

1. a stripped lower receiver
2. a lower parts kit (known in the biz as an LPK)
3. a stock assembly
4. your favorite beverage and/or snack (optional)

Build Party FAQ:

Q: how hard is it to build up an AR-15 lower?
A: it’s not tough. It’s considerably easier, however, if you have a few specialty tools and the assistance of someone who’s done it a few times.

Q: how much will my lower cost?
A: figure on about $250 for a basic lower. You can spend a lot more, if you want to add a match-grade trigger, a fancy stock, or other frills.

Q: is this legal?
A: it is if you do it correctly. A legal AR-15 lower is simple to build, but the rules are somewhat complicated to explain.

• First, the lower receiver is the controlled component; you’ll have to buy this from an FFL and go through the 10-day waiting period to get this.
• You’ll also need to make sure that you DON’T buy a lower that’s on the Kasler list. This shouldn’t be a problem, as illegal lowers are generally tough to find anyway.
• Finally, you should plan to build a legal configuration. The easiest way to do this is with use of a Prince bullet button; you can buy one of these here.

  Update: the maker of the Bullet Button has agreed to furnish a small number of these to us at a discount. Let me know if you’d like me to order one for you.

  Another viable approach is to use the unique stock available from carifles.com. I have one of these stocks, and find it very comfortable and practical.

Q: whose lower, LPK and stock should I buy?
A: that’s really not for me to say. I will say that, in my limited experience with various manufacturers, I haven’t been able to detect significant differences in quality, either in stripped lowers or in LPKs. As far as stocks, personal preference reigns supreme, though there are some legal issues you’ll need to keep in mind (for example, if you get an adjustable stock, you forego the right to a detachable magazine).

Q: where can I get more information?
A: there’s plenty of information online. I recommend strongly that you get acquainted with Calguns.net if you haven’t yet done so. There is an absolute wealth of information there. In particular, if you want to learn more about California-specific criteria for illegal “assault weapons,” take a look at this chart.
