HGN: Welcome to Practically Tactical! Our show is streaming to your eyes like a roundhouse kick to the face! If you want to listen to our 7 level blackbelt and DONT MESS WITH TEXAS style podcast, please search itunes for Practically Tactical.

HGN: Welcome to Practically Tactical Episode 15! This week’s show theme is Walker Texas Ranger, but only because Chuck Norris said so. This episode of Practically Tactical we are doing a topic specific show. We are talking AR15s with our special guest Nate Schultz, or better known as NSZ85 on the YouTube. Nate specializes in building AR15s, roundhouse kicks, handcuffing bad guys to the bed of his pickup truck, and is a writer for

HGN: This week’s show will be AR15 talk, along with some .300 blackout vs 5.56 ballistics, handguards from Unique ARs, Magazine Wraps, the CZ75 Shadow Target, and (insert NSZ’s gear).

WA: We are also joined by Brantley, aka OAF Tactical. When he isn’t shooting competitively or retiring from the Dallas Cowboys to pursue his career as a stunt double for Ranger Jimmy Trivette, he spends his free time collecting my little ponies and making sandwiches for his wife.

HGN: Lets start by introducing myself and then Matt. I run a YouTube channel and Facebook page, both called handgunnewbie. I also love wearing cowboy hats, driving dodge trucks, and running my bar called CD’s Bar and Grill while assisting the Texas Rangers! As usual, I am joined by my co-host Matt. Hows it going Matt?

WA: Hey Everyone I’m Matt from the WalkerArmory...I am your lovely co-host for this fine evening...I also run a gun youtube channel at the WalkerArmory as well as a facebook page. I enjoy long walks on the beach, shooting pistol competitions, and am working growing out my beard in hopes that it will give me even just a glimpse into the Chuck Norris awesomeness...



HGN’s Segment - Eyes of a Ranger

WA’s Segment 

Alright guys lets get into the part of the show everyone has been waiting for..the AR15 segment. Walker Texas Ranger’s round house kick is more deadly than a 30 caliber magazine clip that can fire in half a second...but for the rest of us mortals…we may need to keep one of those awful, black, deadly rifles around...and even more so, know how to build and operate one. For everyone listening and watching we’re going to break this segment up into three different sections with a Q&A break in between each segment to answer any questions that you may have. The sections we’re going to break this up into are acquiring parts and what to look for, building tips and tricks for assembling your rifle, and then last but not least...troubleshooting your gun if you have any problems with it.


Section 1: Acquiring parts

  • What to look for when buying parts
  • Planning out build
  • Upper
  • Barrel length
  • Barrel - Melonite, Stainless, or Chrome?
  • Gas System - DI or Piston - Length (pistol,carbine, rifle, dissipator)
  • Handguards - free float vs. standard
  • Lower
  • billet vs. forged
  • LPK - buffer selection and weights
  • drop in triggers
  • fixed stock vs. adjustable stock
  • other non-standard aftermarket (grips, safeties, BAD lever, optics, etc.)


HGN’s Segment: Live Audience Questions


Section 2: Building tips and tricks

  • Tools needed
  • Bare minimum
  • added niceties

Section 3: Troubleshooting

  • Nate’s Issue
  • Failure to feed
  • Failure to eject
  • Light primer strikes
  • gas system problems and tuning/buffer setups
  • Magazine issues


WA’s Segment: Rapid Fire

Alright guys it’s time to move on to our next segment, RAPID FIRE. The rules of this segment are simple: I will ask you a series of questions and you answer yes or no..there are no explanations allowed...simply a yes or no. Here we go.


  • Are Polymer Lowers any good for AR builds?
  • Are ARs are Better Than AKs?
  • Have you regained your man card after being DOMINATED in the shootout competition by Destinee?
  • Should everyone in the US be required to own an AR15?
  • Is chillable red by franzia the best wine ever made?
  • Is shooting steel case ammo ok in an AR?


  • Is .300 Blackout better than the 5.56?
  • Have You ever Stopped Loving Unicorns?
  • Are CZ pistols the best handgun ever made?
  • Does your wife like me?
  • Would you buy a Glock 42?
  • Is the Magpul AFG better than a vertical foregrip?




Brantley - UD1911 segment -

Alright it’s time to move on to our special co-host segment with OAF. Little know fact, but Chuck Norris is the only person to ever ride a unicorn...I can’t even imagine what he’d do to a UnicornDiva...anyways...the floor is yours Brantley...

Well guys, here recently, as part my my continued desire to build more ARs, I have decided to build an SBR chambered in 300 blackout. Someone asked me at some point why 300 blackout over a 556. Initially, my response was the same I give to explain most all my purchases, “Cause I don't have one yet.”


Regardless, the question spurred me to do a bit of research to see exactly what I would be getting by the switch.

 Besides the typical blog post about how “Bigger holes are better”, and how when suppressed, they “Are quieter than a james bond pistol”, I managed to come across some actual useful data.

Someone had actually taken the time to collect muzzle velocities with respect to barrel length, and compared 5.56 M193 to 110gr Barnes 300 blackout.

So, being the engineer I am, I started plugging the data he gave into a spreadsheet to make some pretty graphs.






  • Once i put the velocities into a graph, you can easily see that for any given barrel length, 556 is faster that 300 blackout.
  • However, what really stood out to me was how flat 300 blackout curve was. By that i mean, as you decrease barrel length you don't lose muzzle velocity as drastically with the 300 as you do with the 556.
  • But, Muzzle velocity does not tell the whole story. Remember, The 556 in question is only a 55 grain projectile, compared to the 110 grain barnes projectile.
  • If you calculated kinetic energy for all these data points, you see that even though muzzle Velocity is slower, for every barrel length the 300 has more energy.
  • What that means is that you can run a shorter barrel in the 300 and still have the same energy as a carbine length 556.
  • Specifically, when comparing these two ammunitions, you can run a 300 with 10 inch barrel and have about the same muzzle energy as a 16 inch 556.
  •  In essence, if you want to run an SBR, you can gain back quite a bit of energy ,i.e. stopping power, by switching over to the 300 blackout.
  •  Now, one thing I haven't done extensive research on is sub-sonic ammunition. But, what I did do is compare the muzzle velocities posted on a box of factory, Right to Bear, 75 grain Sub-sonic 223, to that of a 220 grain, 300 blackout subsonic. Turns out, the 300 has somewhere around 3 times the muzzle energy.
  •  So, there you go Scott. If you are listening to this, thats my answer. Plus, virtually the only thing I will have to change to run the 300 Is a 30 cal barrel.


Project goals were:

  • Create a reliable compact 30-cal solution for AR platform

  • Utilize existing inventory magazines while retaining their full capacity

  • Create the optimal platform for sound and flash suppressed fire

  • Create compatible supersonic ammo that matches 7.62×39mm ballistics

  • Provide the ability to penetrate barriers with high-mass projectiles

  • Provide all capabilities in a lightweight, durable, low recoiling package


After discussion:

John from AAC - 5.56 was designed for 20” barrel and 300BLK was designed for a 9” barrel discussion

WA’s Segment: The Final Showdown


Lets move on to our last segment called, The Final Showdown. This is the segment where we end our show admiring the incomprehensible awesomeness that is Walker, Texas Ranger.

NSZ85: I’m sure you’re staying busy keeping up with writing for the Arms Guide, but what else do you have going on over in your neck of the woods? Anything cool coming up?

 Brantley: Brantley you have just very recently started your YouTube channel, OAF Tactical, even though we keep calling you UnicornDiva1911. So, what are your plans with OAF Tactical and how can we keep up with what you’re going to have coming out?


Brantleys response: Well, for starters make sure you like us on facebook at OAF Tactical.  Also check us out at We actual just posted our first video this past weekend. We have plans to put out several more videos in the upcoming weeks. So far we plan to shoot a detailed review of the CZ-75 SP01 Shadow Target. We will also be talking about concealed carry option specifically the MIC holster. So make sure you're following us on Facebook and Youtube and let us know how we are doing because I’m a pretty pony.  Dont  be afraid to request reviews of any guns or gear you would like to see. Lastly, be sure to let HGN and Walker armory know how I did tonight. I hope you will see more of me in future episodes. I think that about covers it...Well, until next time...Unicorn Out!! <<Awesome Gesture>>

 WA: Well I know we’re planning on having a lot of great stuff coming out at the WalkerArmory. Recently I broke down and finally started a tweeter all you guys that may be interested in that can follow me on Twitter @WalkerArmory, and I’ve also got an Instagram account set up that I can share pictures too. Also make sure you’ve liked my page over at Facebook at and please make sure that you’re subscribed to my channel so that you can be sure and keep up to date with everything we have going on over here.


HGN What about you? What’s new over on your end?

HGN: My next big project will be a polymer torture on AK Magazines. So whenever this global warming of never -80 degrees in Wisconsin ends, I will get to work on that video. I also visited Forest City Tactical the other week, so I have some videos coming out from visiting them down there. Those guys are so cool down there, I actually have to go back down there because we spent too much time BSing. So be on the lookout for some product reviews from them too. I might be working on a taste test of CLPs since I went a little nuts in the after show last week….ANYWAYS...


WA: Last night I was on the Guns and Gear podcast which should be coming out this Friday. We talked about a bunch of gear...some good...some...let’s say not so good. We discussed Tactical Walls a bit which was really awesome...and then our discussion moved on to tree look-alike Sparta shields and Godzilla turkeys...yeah...things got weird. Anyways...make sure and go check out Episode 17 of Guns and Gear podcast at


HGN: Also, be sure to go check out as we have a little competition going on with them. Goto the site, read the rules, download a target, record or photograph your shots and upload them. There will be some serious bragging rights for the winner.

 WA: Yes, that is an open invite to everyone, go to and download that target and give it your best shot...I was apparently disqualified from the competition because they could simply not handle the amount of awesomenes that I submitted. There are leaderboards on the sight and you can go check out the video I submitted along with everyone else to see what you’re up go print the target and submit it for some serious bragging rights! Alright, back to the show, make sure and tune in to Practically Tactical live next wednesday at 7PM CST with Iron Hammer Armory and Kanaz Tactical Group as our special co-host.
