Finishing the Build

  1. Function and Safety Checks

    1. Let the bolt go forward.

    2. Insert a mag and lock it into the mag well.

    3. Pull back smartly on the charging handle. The bolt should lock to the rear. If it does not, check the orientation of the magazine springs. Unlike most pistol magazines, the spring in most AR-15 mil-spec mags is attached to the follower and is difficult to orient backward. But, if it is humanly possible…

    4. Push the charging handle forward into the locked position.

    5. Push the magazine release button. The magazine should fall free under its own weight. If it does not, it could be due to either a bent magazine tube OR the magazine release catch has been screwed too far into the mag well. If you have the same problem with all of your mags, try backing off the catch arm one full turn and repeat the test.

    6. Slap the bolt release. The bolt should fly forward sharply and lock up into the rear of the barrel.

    7. Point the muzzle in a safe direction and put the safety on “Safe”. Pull the trigger, hard. Nothing should happen.

    8. Put the safety on “Fire”. Press the trigger. You should have a normal trigger press and hammer fall. Keep the trigger depressed.

    9. Rack the charging handle.

    10. Let the trigger go forward slowly until you hear and feel the very loud disconnector reset.

    11. Press the trigger again.

    12. Attempt to put the safety on “Safe”. With the hammer down on an AR-15 and variants, the safety cannot be put on safe.

      4. Magazine pulls

 

 

  1. Hitting the range

    1. Zeroing the rifle

 

 

    1. Assessing accuracy

    2. Troubleshooting: Wing Tactical Link

      1. Failure to Feed / Chamber

        1. Magazine problems: Most common malfunction source stemming from improperly seated magazines, spring issues, & follower issues.

        2. Buffer spring problems: Spring problems or improper buffer weight issues.

        3. Defective rounds/ammunition borne malfunction: set back, stubbed rounds, bad primers, ammunition stuck.

      2. Brass Over Bolt (Bolt Override)

      3. Failure to Feed b/c Dirt, Debris, and Fouling: Short Stroke

      4. Failure to Fire: look to the firing pin

      5. Failure to Extract

        1. Short Recoil – see the section above on short stroke due to dirt, debris, and fouling.

        2. Fouled or Corroded Chamber – Inspect and clean, then determine if the chamber is damaged or safe to return to service. If it is damaged, the barrel will need to be replaced.

        3. Weak or Broken Extractor Spring – replace spring that is no longer serviceable.

      6. Failure to Eject - Most of the time this malfunction is caused by:

        1. Short stroking (we covered short recoil earlier); or

        2. Fouling or corrosion of the chamber which causes friction on extraction throwing off extraction and ejection functions.

The fine folks at Otis Technology have sent over a mountain of rifle maintenance tools and cleaning kits for the AR-15 and AR-10.  We’ve been tasked with giving them away.  Watch for the special posts on Facebook and Instagram to get a chance to win some of the awesome products made by Otis Technology.  We’ll give away a complete MSR Cleaning kit in either 5.56 or 7.62 in the middle of each  month up until Christmas, when we’ll give away a complete Otis Technology Elite Cleaning System to one lucky listener.  During the alternating weeks, we’ll be giving away a host of Otis tools and cleaning supplies.

Feedback:

Hugh P:  You guys should check it out the AXTS Talon safety selectors (same company that makes the Raptor charging handle). They are 45 degree and (unlike the Battle Arms ones) will work on any lower receiver. They also have the ability to be converted to standard 90 degree selectors in a few minutes (see the video on their website). I used to have the BAD sectors but have since switched over to the AXTS ones on all my AR's. Also, can you guys do a podcast on linear compensators and the current crop of muzzle device covers that mitigate side blast that accompanies compensators (FerFrans CRD, Kineti-Tech, Lantac BMD, Surefire Blast Diffuser/Warden, Griffin Armament Blast Shield, etc.)? Would be great to hear the pros and cons as well as how the covers change the effectiveness of the muzzle devices under them. Keep up the great work.

Bob L:  Reed, another common and inexpensive method is to  use a clevis pin to prevent launching the spring.

Dan V:  Thanks for the shoutout on your show this week...I was the guy that recommended adding the search function to your site to help other listeners find episodes, etc.  Wow...should something that helpful be recognized???  Gee you guys just mentioned ar cleaning kits piled to the sky at the secret headquarters.  Feel free to send one along to me to make more space for your quality programming…

@enzorifleworks:

@dylan.h.cave: Upgrade! Upgrade! Upgrade!  On the best day of the week too.  now it’s time for some range time.  Thanks for the excellent article on muzzle devices @guntruth.

@bigbiller: For some reason, I left laughing out loud by myself.  Connecting w/148 and 248 yd steel targets through iron sights w/rusty Tula .223 through the M&P consistently w/ease was apparently humorous.  Guess you had to be there . . . .

Listener Feedback:

Ray H:  First off love listening to you all while I drive up and down the state of California.  Well you guys and the rest of the Firearms Radio Network got me to build an AR15.  I thought was all corny when Reed would read in the beginning of the show how Jake would shot a detent into the carpet then on to the linoleum floor. Found out first hand the rear dent spring are tiny missile. Thank god my wife was at work I wouldn't have wanted her to see two 44 year old brothers face down on the kitchen floor looking for that spring.  Had order a replacement as that first one is gone somewhere in the darkness of the evil tile floor. Thanks   Ian Kay:  Hi Reed, JW and Anthony, Another great an informative episode, thank you! Thanks for the SCAR profile on a show about the Stoner platform, I'm not sure why it feels ok to do that, (as opposed to any other modern battle rifle), but it just does. Clearly its easy to understand, when compared to the M4 why the Mk16 was not adopted. But the Mk17, when you need to cover a half kilometer, it looks like one of the best .30 cal rifles today. I would be interested though to compare the SR25 and a Mk17 set up in the DMR role, which one has better accuracy. My guess would be the AR, having all that gas and piston hardware hanging off the end of the Mk17 barrel can’t be that good. I’ve always appreciated how with a free float rail the AR barrel is almost naked, with little to disturb the harmonics. I’ve always been interested in the SCAR because it was trying to be a replacement, and as great as it is, still not any real improvement over the AR. In my opinion the real problem is the cartridge, if you think adopting a new rifle is difficult, consider changing the NATO standard! I especially enjoyed JWs perspective and first hand knowledge of the platform, I don’t think that a lot of people (myself included) have had the chance to try one, so his experience and insight was really appreciated. Finally, I’ve heard that the next gen SCAR will look a bit like the FNAC, non recip charging handle and the front sight moved off the gas block. Pretty cool! Thanks again,
