Listener Feedback…

Samuel B: Hi guys. Love the show!  When I build my next AR I am considering putting a scope and offset iron sights on it. My question is, with options ranging in price from $20 to $200.  Are there any offset irons that you guys can suggest based on positive personal experience? Thank you.

Curt H: Guys, I've been having a discussion with a friend about the 300 blackout he wants. He claims that a piston system works better with a silencer than DI. Do you know if this is true and if so why?

kiki kiki: Hello Reed and JD..... I have one AR-15 Lower and multiple uppers... all my uppers have an assortment of different 2 chamber muzzle brakes... from Surefire procomp to Wheaton arms 2 chamber brake! what these brakes all have in common is carbon build up on barrel crown face! No matter how many times I clean them, few 100 rounds later build up back! Cleaning becomes a pain, since you have to remove muzzle brake and reinstall and time with a new Crush Washer! Is this something I should worry about or just ignore...thanks kiki

Don: Glad to hear you back after a few weeks away. My question is about acceptable weight range for an AR-15. I just finished my first AR-15, built from sourced upper and lowers as opposed to building completely from scratch. Unloaded and with optic and BUIS it comes in at 8 lbs even. I know weight is subjective and depends on intended use but what do you think a normal weight range should be for a defensive rifle?

Dan C: Hey guys, I love the show, I've listened for years. Just like on all of Reed's rifles my iron sights are always up. I was wondering if you guys were ever planning on doing a show about the Fostech and Franklin Armory binary triggers, these are amazing developments and honestly seem better than an actual full auto. Though of course I'd like the Hughes Amendment to go away just as much as anyone. Love the show and Reed is for sure my favorite host, nothing against the other guys at all lol.

Zachary D: I know you've done several shows about acquiring NFA items, but don't think you've ever done one about what the rules are after you get your items. I envision this being similar to what a lawyer would provide to his client after drafting up a trust and the do's and don'ts for staying out of trouble.

Suggested topics include:

1. Traveling with your items;

2. federal laws, vs. state;

3. Do you really need to get permission from the ATF to transport across state lines?

4. How far ahead do you need to start planning if you do need ATF approval?

5. Does federal law trump state law when it comes to NFA items?
6. Loaning your items out - Is it ok to hand to the guy next to you at the range to let him try your silencer / SBR?

7. What about letting your wife or child use the item if they're not on your trust?

Shawn E: I live in Minnesota, which like a lot of states has regional separation during deer hunting for the legal means to take deer. I happen to reside in the shotgun zone, but we have several guys who hunt with rifle-caliber pistols.

Thinking of possible range, recoil, and repeat shots, I thought I would build an AR pistol in .300 AAC Blackout. One of the reasons I like it over a traditional pistol platform is that three points of contact, rather than one or two can be made with a traditional handgun. The fore end, grip, and the cheek weld on the buffer tube help to steady it a bit more than a traditional revolver or single-shot rifle-caliber pistol. With its weight, combined with its semi-auto bolt, it soaks up the recoil of the round pretty well.

So, flatter shooting, longer range, better stability, easy-to-mount optics, less upward recoil all make the AR pistol attractive to deer hunting where I am.

Thanks for a great podcast.  I actually like when you guys eat food on the air – it gives the show an “earthy” quality of sitting around the table in a hunting shack, a feed store, or somewhere else where folks are comfortable, normal, and real.

Main Topic:

Hard anodizing is typically applied to heavy wear industrial parts intended for use in aggressive or highly corrosive applications. These coatings are typically far thicker and harder than decorative ones, and usually lend the parts a durability approaching that of hard faced or case hardened steel.

Hardcoated items usually have a dark gray to a black finish. This can vary depending on the aluminum alloy.

One of the main purposes of hard anodizing is to make the aluminum more resistant to corrosion. The thicker oxidized layer protects the finished part from being exposed to moisture, oxygen, and other factors. Sealed items are even more corrosion resistant.

The outer coating is also extremely hard, typically much harder than the original metal. In many cases, a thick hard anodized coating can be as hard as tool steel.

The oxide layer is part of the metal, it won't peel off and the surface finish will increase.

Hard anodized metals are usually very well insulated they don't conduct heat or electricity well.

This is especially useful for applications that require the part be used at high temperatures.

From AR15.com

Forged is typically a piece of material that is smashed into a shape while it is red hot (when referring to a shaped object for rough or final product). The grain structure of the metal material will follow the shape of the unit being produced. (ETA: forged material can also have no particular shape to make forged blank material to be machined into smaller pieces but retaining the strength of the initial forge)

Billet is a more general term used to describe a piece machined from a chunk of material/metal.

The original piece is most likely some sort of casting or drawn out, formed piece of metal.

In simple terms forged is probably going to be stronger.

Billet strength is dependent on the original slug of metal it was machined from.

Billet uppers or lowers can be more pleasing to the eye however due to more machining operations to achieve the final product. A forged or cast piece will usually be a rough resemblance of the final product and some areas may not need a finished surfaced machining/milling.

To add to the confusion you can have a piece that is forged and billet at the same time if the parent material stock was forged.

On another note: Take for instance a crank shaft for an engine that is forged into it's final shape then machined. The shaped forged crankshaft would be stronger than a crank that was machined from a forged piece of billet material due to the grain structure following the shape of the forging.

Feedback:

Ryan H: I just had a quick question. Getting ready to do my first build and wondered what your opinion is on the Reliabolt from SRC. From what little I have seen/heard it seems like a nice option, however I have seen a couple of YouTube videos saying they were junk and have broken. I don't know many AR guys so I thought it would be a good way to pick several brains at once. Thanks and love the show.

Keith S: In the event of an EMP, first people won't know what happened... but if your watch is out along with the power, laptops, cars, etc... you can guess what happened fairly quickly.

You'll need info on the area you've traveled to for business, I imagine Reed on a trip, business suit, briefcase, etc. First thing I'd do is secure shoes and any clothing needed for the long haul home (rain gear). (before you go on the trip know where sporting good stores are in your area, you won't be able to google them afterwards)

Second, hit the grocery store and stock up on something like Ramen Noodles, lightweight and easy to carry (wise to know where they are in your travel area as well).  Third, you talk about trying to trade for a car? ever car on the highway died in place and no one is clearing the roads... get a bicycle, you can always carry it around blockages etc.

A few years ago here in the PNW, we lost power for a week... some areas for longer. Gas stations that had power to pump gas had lines backed up for miles..stores weren't being resupplied and shelves were bare. My take from that experience was, I was prepared enough to get by for a week so I didn't need to go out and get stuff... but after a week, it was mostly gone and too late to go get and I realized that in the event of something really major happening that you needed to react first and fast or else it would be too late. So get your boots, raincoat, bike and some food to get you going and go quickly.

Love the podcast, it's like being part of a conversation of good friends that I would love to join in the discussion... but talking back to my car stereo never gets a response from you guys ha ha.

As for Reed's obsession with iron sights, I was in the Corps a few years before he was.. and I totally get it... as he ages, he'll want optics so he can focus better... it's just a matter of time.

Keep up the good work and I hope you all are enjoying making the podcast as I am enjoying listening to them.
