Brent W:  Reed, I just bought a fn15 from Bud's. I would like to swap the factory hand rail with a 12" carbon fiber quad rail. Any problems in my future with the a2 front sight of the gas block? Thanks

2k4ranger: Hello since you have been talking a lot about Appleseed a lot on the podcast i just wanted to leave my 2 cents on my Appleseed experience. Just so we're clear I'm a self taught shooter and mostly shoot bench rest and pistol.

I went to an Appleseed class in northern WI and was very disappointed, maybe I just had a bad instructor or I'm too stuck in my ways but I would personally not recommend the Appleseed project to anyone.I was extremely disappointed in the instruction, and found the techniques with the sling manipulation to be extremely unpractical in both hunting and range shooting, I wish I could have my 22lr back.

Anyways just my personal experience.  Thanks for the excellent podcast.  Always learn something new every time I listen.

Anthony F: Hi, I am a long time fan of the black rifle and was really excited when I found your podcast. I looked through the back catalog of podcasts and could not wait to start listening. I finished listening to the two latest episodes and liked the information they contained but I have found the audio quality makes it difficult to listen to. I tend to listen to podcasts when I am driving, exercising or reloading and it was frustrating to have to keep rewinding the audio stream to try and catch what I missed the first time. I use an Android phone with an app called Pocket Cast to stream the audio and either the bluetooth in my car or beats headphones to listen. I don't seem to have this problem with other audio feeds so I don't think it is my equipment. Is there any plans to upgrade the audio quality of the show or are there and audio streams that are better than others? Thank you.

Dave in New Mexico:  Reed,I just finished listening to podcast #87 and what a struggle it was to understand you and JW. The audio quality was poor and you both sound like you were talking in a tin can. Your words sounded run together and very muddy, not clear and crisp. Can you borrow Jake’s microphone that, that he can’t afford, and use it?? Please go back and listen to see if you are not hearing what I am, if you aren’t and it sounds fine to you then disregard this e-mail I listen to yours and other Firearm Radio Network Podcasts on iTunes.
