Listener Feedback…

Tyler Wiese -  Thoughts on 6.8SPC and Grendel. Things from range, huntability, bullet selection, reloading, and trusted barrel/bolt makers. Would also love a whole wildcats show, with as many calibers and info as you can get. Also thoughts on the AR10 platform’s 45 RAPTOR

Jason Kruse - I would like to hear your guys opinion and take on the NRA and how people are becoming so disappointed in that organization. Also are there any good alternatives. Also would like your take on the 7.62 X 39 round in the AR platform.

Joe Oliveira - Proper cleaning times and methods. When to or not use a borebrush.

Craig Valentine - I have a 14.5" BCM carbine length barrel. What weight buffer should I be running to help compensate for the barrel length? I also have a rifle length BCM that feels much different. I also Know it's a longer gas system. I'm just wondering if changing my buffer weight(currently a 4.3)would help. I am running a JP Enterprises carbine length polished silent spring with it (not the silent capture)Thanks guys!!
Robert Mate - I have a old(1945) browning A-5 12 gauge shotgun that is in rough condition but still functions fine it just looks bad. No pitting but definitely needs redone.It was kinda handed down to me from my wife's uncle who isn't with us anymore. I am wondering if I should have it cerakoted or just keep shooting it and keep it from getting worse or try to contact browning to see about a reblue and service

Brandon Dhondt - I'm in the parts buying phase of my first build, a .308 composed mostly of Aero Precision components. I'm looking for a good reliable adjustable gas block, more particularly in Stainless vs black. I'm leaning towards the JP adjustable block but am concerned if the adjustability while the handguard is on since the adjustment screw is on the side of the block.
Any input would be great as far as other companies to look into or experiences with the JP block.

Connor R. Hebdon - Same idea as Robert below. What are some good 80% lowers and/or jig sets. I have a 5D tactical jig and I made some Bear creek arsenal lowers (worked really well actually) and always looking for more options

Alex Stephenson - I'd love to hear you guys talk about M16-A1 and M16-A2 clones.

Robert Mate - 80% lowers worth the hassle or not?

Justin Hope - Adjustable gas blocks. Hydraulic buffers. Opinions?

Jason - Got a question for the old man... or anyone else out there. Looking for some good but inexpensive iron sights for the AR-15 and 10 platforms. Thanks all.

               AR-15 Market Right Now

               Shirts for the Show - Ideas for a logo?   

Jeff  - Hey guys! Looking to get a BCG for my build and was thinking of going melonite. Could you recommend what you would consider is the best on the market? Cost is not a factor.

Seth - Thanks guys. First time using the Otis cleaning tools. Won the bone tool last year. Love it. Looking forward to another great year of content. Keep up the good work guys.

Tyler - Looking at building an AR for my older brother, he wants something other than 5.56 but still something similar and easy to find. Thinking a 7.62x39 due to cheap ammo and it's an all around decent cartridge. Besides prebuilt ones that are ridiculously expensive, do you have any build suggestions? I'm hoping to stay with a plane Jane lower that can take any normal AR upper so if I wanna get him a present in the future I can build him an upper. Anyways like I said, I've heard there's some reliability issues in feeding and seen some forums where the guys all ground down their feed ramps and bored out a slightly larger gas port and they worked fine.  Any advice helps

Tyler Dice PSA barrels are made by FN. But are PSA barrels made to PSA spec, or FN spec?

AR-15 Podcast 170 - New Frontier Armory Giveaway

 

Feedback:

DW Taylor:  A few months back I had asked about your thoughts on the 6.5 Grendel. I had listened to past episodes that had touched on it, but episode 162 went into great details on the topic. Thanks for the very informative episode. Looks like that will be my next build.

Just to let you know, it isn't cheap to listen to your show. Since listening to the various topics, I've now milled 7 80% lowers, built an AR15 chambered for the 7.62x39, built an AK47, bought a night vision scope, made sure all my builds have iron sights, and now you guys keep talking about the AR 15 in 9mm...

So, should I stop listening or just buy another gun safe?

Keith S:  Long time listener (my review was read on episode 11... proof I've been around awhile).  I've been thinking of a competition between the show hosts. Each one builds a rifle from scratch... within a given budget.  Say you have $900 to spend or $1000... each week the host share what part they bought and cost and why... my assumption is that say week 1 - it's lower receivers... week 2 - lower parts kit ... week 3.. stocks.. etc. so that everyone is talking about the same part.  In the end each gun is submitted to a neutral party (I'll gladly fly out to Reed's house for a weekend of shooting). The winner gets bragging rights and the 3 rifles are awarded as prizes in a drawing... first place gets the rifle that the neutral party feels is best.. 2nd gets the 2nd best and 3rd gets the last one.... or maybe the winner keeps his rifle and the others are awarded in a drawing.

The rules... no parts that you already have.... must be purchased and costs kept track of so we can. Any tools that would be required to be purchased don't count towards the cost (just assume you borrowed them from a friend). I have a few twists/tricks that could throw the game around but it would be fun for you guys (and if I got to be the neutral party fun for me... but fun for me just to listen to as well).  I assume some will put money for the build aside for a scope, Reed wouldn't and would iron sights on.. etc... would be fun.  Everyone would have their own strategy on the build.  Anyway, it's something I've been kicking around for awhile and hopefully you can get Jake or a sponsor to kick in the money for it.  Enjoying the show for more than 3 years, keep up the good work... and get more range time when you can.

Semper Fi, Keith

Giveaway: New Frontier Armory 9mm Carbine

Main Topic: 6.5 Grendel

History

  • The 6.5 projectile has a long history in Europe
  • Common examples include 6.5x52mm Carcano, 6.5x54mm Mannlicher-Schoenauer, 6.5-284 Norma, and 6.5x57mm Mauser
  • Developed by Bill Alexander, Arne Brennan, and Janne Pohjoispää
  • The cartridge’s development begins with the Soviet 7.62x39
  • The cartridge was next modified for european competition by necking down the cartridge to the 220 Russian
  • The next evolution saw the shoulder of the case blown out to create the 22 PPC and the 6mm PPC
  • The designers started with the 6mm PPC and moved into 6.5mm projectiles
  • The final changes included expanding internal capacity by shifting the shoulder forward and the wall thickness in the neck and shoulder was increased
  • First unveiled in May of 2003, it was introduced in January 2004 at the SHOT Show

Commercially available AR’s Chambered for 6.5 Grendel

  • Alexander Arms
  • CORE Rifle Systems

Building your own 6.5 Grendel AR

  • Requires a nonstandard bolt and barrel
  • 26 rnd capacity in standard 30 round magazines
  • You are required to compromise on the matter of barrel length. Your rifle needs a heavier bullet in order to shorten the barrel, but due to the platform’s dimensions, you are limited to lighter bullets.
  • Barrels - Brownells, Shilen, AR-Stoner
  • JP Rifle bolt.

Ammunition: Manufactured and Reloaded

  • Alexander Arms trademarked the 6.5 Grendel.  It wasn’t until they released the trademark that the cartridge was allowed to become SAAMI standardized.
  • Before AA released the trademark, other companies chambered the round and re-labeled their chambers (i.e. the 264 LBC and 6.5 BPC).
  • Prvi Partizan, Wolf and Hornady produce 6.5 mm Grendel factory ammunition
  • 6.5mm bullets can generally range from 90-160 grains, the Grendel seems to stretch no further than 144 grain projectiles
  • Reloading Dies:  Redding, Lee, Hornady, Forster
  • Brass: Norma, Lapua, Hornady

Why do I want the 6.5 Grendel?

  • With its higher BC, it is still supersonic at 1200 yards
  • Superior external ballistics compared to the 7.62 NATO
  • Reliability in the platform
  • Superior ext’l and terminal ballistics compared to the state of the art
  • Pinnacle chambering for the platform
  • Perfect match as opposed to series of compromises
  • Flat shooting round
  • Half the felt recoil of a 7.62 Nato M80 ball
  • Very active online community - http://www.65grendel.com/forum/

Feedback:

John Marston:  Good afternoon AR15 Podcast. Long time listener, very infrequent poster. Just a small correction and the info posted on episode 161. In regards to the assault weapons ban one of the hosts listed Hawaii as one of those states. I live here and the AR15, SCAR, or AK47 are not banned. We can even own standard capacity magazines. However, we must register all our firearms, so not so free. Keep up the good work.

Tim:  Hello, Love the podcast! I've been an avid shooter since I could safely handle a rifle and a collector since I started working. My passion has always been military bolt guns and competing with them in "service rifle" type matches. I'm a machinist by trade and have been at it since I was a 17 year old apprentice (I'll be 48 in March).
I presently run the machine shop for an optical instrument company. Several companies you've interviewed are customers of ours.  I recently completed my first AR build and I'm kicking myself for not doing it sooner.  I'm a convert to the black rifle now, and have several other rifles in various stages of completion.
Now onto the clamp on gas blocks. I think you are selling that method a bit short, in fact it's a much better way of securing them than a dimpled set screw.  Think of how the fork tubes are secured to the front of a motorcycle, particularly a high flying motocross bike.  They're clamped. When properly machined the surface contact of a clamp on gas block is far superior than the set screw method. The set screw pushes on just two points, the set screw itself and the opposite side of the barrel.
Technically, the area of surface contact could be as little as 3-4 percent with set screws and as much as 95 percent with a clamp on block. For longer ranges those two pressure points would tend to mess with the mystical "barrel harmonics" much more than a block squeezing equally almost all the way around the barrel.
I know optics have been know to slip in a set of rings, but properly lapped and torqued scope rings are the strongest point in that situation, where as any "slippage" should be coming from where the rings contact the rail. Also. securing a clamp on gas block over a 3/4" barrel with a side wall thickness of over 1/4" lends itself to much greater torque than the thin walled aluminum tube of scope.
I know opinions are like "backsides". Everyone has one and they all stink :-)
But I'm taking 30 years of machining/engineering knowledge and putting it out there for anyone who may listen.
Thanks again guys, I love this podcast and have learned a lot from you all.

Tom G: Damn you guys are great enablers. I broke down and bought LWRC compact stock system for my SBR.  I will post updated pics when I have a chance. Thomas Gonzalez

Zane:  Gentlemen, Great show. One thing that I think worth bringing up is the purpose of the rifle can greatly change where to save money. I think a home defence gun, cops duty gun, a long range toy and a plinking toy should absolutely not save money in the same places. For example my HD gun has high quality buis and red dot. My hog/plinking gun doesn't even have buis and If the cheap optic goes down, oh well pack it up and head home. Keep up the good work.  Just a thought.

Nick: Hello gentlemen, I would like to extend a huge thank you for the amazing content you guys provide. Like many I started by buying off the shelf but as my black rifle disease continued to spread I began building my own. With help from many past episodes I've become more familiar with the platform. As I start my next build I would appreciate if you go in depth in the ar pistol world while maintaining a budget. Keep up the great work.

Charles:  Great podcast guys. I started listening back in Dec. And haven't stopped. In podcast 160 you mentioned iTunes problems. About three weeks ago the podcast stopped downloading on my Android player. Just figured you all took some time off. Yesterday I found a new link for your podcast in player FM. Maybe it's not just an apple issue. Keep the informative podcast and thanks!

Joseph T:  I have recently built a 6.5 grendel after previously building a .223 and a 6.8. I am a frequent deer, hog and exotic hunter here in TX and wanted to build the best all around hunting MSR I could without jumping up to .308. I had taken deer and hogs with both the .223 and 6.8 but wanted the range and knockdown power of the 6.5. My suggestion is in regards to a show about tuning with muzzle breaks, buffer springs and buffers to achieve the lowest recoil/ best action/ejection possible when stepping up to rounds such as the 6.5. I recently learned that there is a whole new world regarding these items that I had never even thought about.
Recently got the bug for black rifles again after a short hiatus. I have
been listening for about a year and love the show.
