SirGilligan:  Thank you very much for mentioning my app Gun Log SPC! As mentioned, Gun Log SPC does not use iCloud and your data is only on your device. The app does not (nor ever will) take any of your data and send it somewhere else. The Gun Log apps are first and foremost range logs. You have to have your inventory of firearms and ammunition to make a good range log, so the app is also an excellent inventory app. The app tracks failures, firing sets, maintenance, and all more. I also wrote a G1 ballistics calculator to help you get on paper. I wrote all the code, there are no third party libraries, in the app at all. With that said, that is the reason there is no bar code scanner, I did not want to use a third party software tool to read bar codes without knowing that the bar code scanner library isn't harvesting data. You can read about the app here:

I would love to give the give Mr. Hardy some free downloads of Gun Log SPC that could be shared with your audience. If he will contact me, the contact info is in the app, I will hook him up so he can hook you up.

There is only me, one programmer, no one else. I do this on the side.

Have 10 FRN listeners contacted you "guys" about Shot Show yet?


Hey guys, finally getting caught up on podcasts (ARP 097) and thought I would send a picture of this monstrosity I saw at the 2014 Chicago gun show... It's like playing Where's Waldo trying to find the muzzle from the front. Still lovin the podcast and it's really great how the show has progressed in quality and content.

I'd love to hear what Patriot Ordnance Firearms (POF) has going on if you guys see them at Shot Show, don't recall you guys ever mentioning them, really a very solid gun. I've owned one for a while, mine is the 18" version, fluted barrel, button rifled, piston gun with a really nice POF trigger. Very accurate, low muzzle rise and allows faster follow up shots than any other AR I have shot. Only downside of the rifle is weight, pretty noticeable, especially after a full day of shooting and lugging around from stage to stage.

Your show inspired me to build an AR on my own and am really glad I did. Decided to do a lightweight version unlike the POF. I went with a Rock River 2 stage based on a friends advice...not my cup tea, feels more like excess creep more than anything else and don't really like the longer reset. I don't get the fascination with those. Anyway I will end up replacing with the POF single stage, again, a big fan, very crisp.

Keep up the great podcast!

Mike R, Skagit Shooting Range:

Reed, Anthony, JR - What a great show as always, you all bring a great element to the podcast.

First of all - Why the heck don't Rick and his "team" of survivors use the suppressors all the time? It really frustrates me on so many levels - First those walkers are attracted to sound. Second  your hearing? I'm thinking it's really important to have great hearing in the zombie Apocalypse. I'd love to see a 300 Blackout SBR suppressed - those 220 SMK must do wonders on the walking dead!

Alright - I must admit, after hearing you guys talking about getting to the range - well I get to the range several times a week, but I don't get to shoot as much as I'd like to - because I work there. Crazy as it may seem. I have to force myself to get out there to shoot - and I have 50+ guns in the rental counter if I don't want to shoot and clean mine.

I heard about some of the topics coming up - can't wait.

Can you talk about head space again - and your experience with head spacing your new build ARs. I've not head spaced any of mine yet.

I'm always interested in hearing technical info about the AR - springs, triggers, where to lube etc. Perhaps a maintenance performance tip of the week segment?

Shot show meet up, I'm in - Tue/Wed/Thur are all open


To all the Hosts at The AR 15 Podcast,

I wanted to take a chance to write and thank you for your show.  Growing up and living most of my life in Pennsylvania, I never had an interest in the AR platform until recently, since they are not legal for hunting.

I became more curious about AR in recent years and found your show early this year through a link on's Daily Bulletin.  I started listening to the podcast from the first episode and working forward until I caught up.

I had to learn everything from your shows.  The technical feedback from Bob and others was fascinating.  The more you taught me, the more interested I became.  I decided it might be fun to learn about these new fangled space guns by putting one together.

I talked it over with my wife, Cathy, and decided to raise money for the project by collecting aluminum cans on my jogs.  I was slowly saving money until a co-worker took off several months for medical reasons and I had to work many more hours while he was out.  At first I was rather bummed because I was spending so much time at work, I did not have time to collect cans, but I talked it over with Cathy, and she agreed I could put $5 from every hour I worked overtime toward the gun.  That certainly helped my savings increase faster.

Trying to decide what to build took some thought.  As I have no experience with these fancy auto-loading rifles, I decided to start closer to the beginning, so I ordered an imported  M16A1 parts kit advertised on  After searching the web, I wasn't quite sure which parts I had to get rid of before buying a receiver, so to make sure I got rid of the M16A1 trigger, disconnect, hammer, sear, and safety selector.  Does anyone besides me find it strange that it is alright to import the fully automatic fire control group with these old guns, but not the barrel?

I wanted to keep the gun as authentic as I could, so I bought a 20 inch barrel with a 1 in 12 inch twist in the M16A1 profile, a M16A1 profile lower receiver, and a standard fire control group.  I used original parts wherever I could.

After putting the gun together and breaking in the barrel, I completely disassembled it and took it back to my parents house over Thanksgiving.  My Dad and I put it back together and fired hundreds of rounds with no failures.

It guns shoots great, but boy is it ever a rattle trap, especially with earmuffs contacting the stock amplifying the sounds of the action spring flailing around.  The ergonomics are all wacky for me as well.  The A1 stock is very short, placing my eyes real close to the rear sight, causing me to blink every time the gun recoils.  The grip is so close to the trigger, that my second knuckle sticks past the trigger, my finger is bent at an uncomfortable angle to get the ball of my finger on the trigger.

The gun is a nice toy, but I can't see it every replacing my Marlin 30-30 as a go-to rifle.

My Dad borrowed the gun for some classes he is giving to people from his church using flintlocks, Garands, M1 Carbines, and other historical military firearms.

In the future I would be interested in trying to build an AR10 platform with a 24 inch 7mm-08 barrel, but after seeing how the barrel is held on, I don't know if the  aluminum receiver would be strong enough for a barrel that long.  A longer barrel would likely mess up the gas system dwell time as well and cause problems, or at least cycle the bolt before the bullet has left the barrel, making the extra length worthless.

I will attach a picture of my Dad, Jim, with the AR15.  We tell people he is clowning around, but in reality, he likes to discourage any potential suitors for his 5 granddaughters (and at least one more on the way).

Thanks again for the show.
