The Lower Receiver Assembly

  • The Receiver
  • Not much to be done to begin
  • The Lower Receiver Parts
  • start with the mag release
  • bolt catch is next in the install
  • protect your receiver when installing roll pins
  • Pivot pin is my next priority
  • I install my trigger before the safety selector
  • install the grip to retain the safety selector
  • the Takedown pin is held in place by a spring and detent, I usually install the Takedown pin last unless the spring is captured by the grip (which depends on which receiver you get)
  • install the hammer next followed by
  • Receiver Extension Tube
  • advance the castle nut up the tube as far as it will go
  • work the endplate as close to the castle nut as it will go
  • remove the Takedown pin detent spring
  • thread the tube into the receiver until just before the lip catches the buffer retainer
  • depress the buffer retainer and advance the tube enough to reveal the milled detent hole in the receiver
  • install the Takedown pin detent spring
  • rotate the tube back in line with the receiver
  • work the endplate as close to the receiver as possible without kinking the Takedown pin detent spring
  • tighten the castle nut to its final position
  • Buffer and Buffer Spring
  • work the spring and buffer into the receiver extension tube

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:

Mike:  Guys - Great show as usual. Thanks for revisiting the AR build. Really enjoyed this episode.  Really been thinking about a 264 LBC build, but not sure when it may happen. Any coverage of muzzle breaks and or suppressors would interest me for show topics. I know it's revisit for muzzle breaks.

jscanter:  I really think that you are going to like your Daniel Defense butt stock. I bought one for my build and think it's great.

Joe C:   Hey guys, always a great show. I have semi-finished my build up to the optics and can read all about them, but until I can see them in a store they'll have to wait. You always ask for a list of the build so here goes.

Mega Arms Maten billet upper/lower set w/ mkm extended rifle length (15") hand rail; Daniel defense buttstock; JP silent captured spring; AXTS raptor charging handle; Lord Arms BCG w/ CX6 finish; Geiselle SSA-E trigger; Magpul MOE+ grip; Noveske end plate w/QD attachment

BAD-CASS safety; Rainier Arms extended mag release; Diamond Head front and rear sights; Rainier Arms 18" barrel; Battle Comp BABC compensator; Odin Works handstop; and a Savvy Sniper Cobra QUAD X Sling

Tried very hard to make sure everything I bought was made in the USA. Thanks a lot guys, I'll send you some Instagram pics and let you know how it works.

Feedback:

Kyle:  I tried to zero out the AR this weekend. Apparently it shoots to the left as I had to adjust the rear sight to the right. Is this common? Should I try to adjust the front sight post or is it not worth the hassle? Currently using an f marked front  sight and A2 style rear detachable carry handle. I would appreciate any information you have available.

Shawn, St. Louis:  Hey guys, love listening to the ar15 podcast during my free time.  For me the best part of your show is having real industry speakers on your show vs guys that just like to shoot. It really helps me narrow down the best products for the ar15. You do an excellent job of asking a good informative questions when interviewing.  Keep up the good work.

DW Taylor:  A few weeks back I had asked about the 6.5 Grendel. Since then, I have discovered your search engine. Using that I found the old podcasts that went into detail on the 6.5 caliber. Thanks for being proactive and having those in the library for me to review. I am slowly working my way through the backlog of older podcasts. I would prefer to do this on Stitcher, but they don’t go back too far. I use my PC for the earlier ones.

My first AR15 is the S&W MP15 Sport. I let some friends give it a try as I was working on my handgun skills. They burned through 9, 30 round magazines in about 20 minutes. How hot will a barrel get after this much rapid fire? What will this do the barrel? Can the barrel handle this rate of fire, or will it wear, loose strength, accuracy, etc. It isn’t a match-grade barrel, so I am not as concerned with sub-MOA groupings, but just an overall understanding of what a black rifle can be expected to take.  After all, we own them so we can shoot them, right?

Hello feedback!!! My name is Evgeniya, to me of 25 years. I live in Russia.  I saw your your profile and you interested me very much!

I want to find the man of my dream.  I would like to get acquainted with the person who might appreciate my care, tenderness and love. I want, that you would be responsible, capable to give a hand of the help and to sympathize with me in any problems.  If you agree with me write to me, I shall be glad. I shall answer you soon. In my turn I shall try be the offer, loving, devoted, responsible woman.  If you decide to write to me, I wait for your answer very much !!!

@dylan.h.cave: Wishing my range wasn’t closed on Mondays.

@dylan.h.cave: One fierce hatchet.

@msr300blk: My 6.8 SPC build, waiting on the Silencerco Trifecta muzzle break to button up my Odin Works handguard.  Running an ALG Combat Trigger, 16” Wilson Combat 1:11 twist SS barrel.  Waiting my pre-ordered 1-6 Vortex Strike Eagle to be shipped but in the mean time will go with some Magpul Mbus I have laying around.

@lambo415: Very happy with my Vortex Optics StrikeFire2 and magnifier.

@jtkustomizer: 25yd semi indoor shooting range @eagledefense.net  Pretty awesome place just wish it was closer to the house than it was.

Listener Feedback:

Robert: Jake Great to hear about ar-15 podcast just bought my first this year and love it. Also just finished gun store and range show and would like to recommend Dabbs gun and pawn on horn lake,ms great people and great place to buy guns as far as gun ranges I belong to Desoto Rifle & Pistol club in como,ms outdoor range that is great.Thanks for great podcast!

Kiki:  Dude like the new show, but you guys failed in the most popular ar rounds side....at least in my neck of the woods besides 223/556....308 nato, 9mm and 22 lr rule.....not to many people go to wild cat rounds like grendal, 6.8spc or 300 aac around here.....alot of 308s and 9mm carbines.....anyway keep it up...

Josh Wood - Dallas, TX:  Jake, You read my email on air about Targetmaster in Garland. Is there anything that can be done to increase my chances of winning? :) I got a wonderful deal on a mostly milspec AR for $500 from a friend that was desperate for some cash. Did a little work on a Glock I sold him for the price. Anyhow, I love the rifle, but while  the charging handle looks black and matches in low lighting, it is actually purple! I don't know if he cannibalized this from his wife's rifle or what, but man would I love that sweet charging handle. Anyhow, mostly joking. I did give you a five star review on iTunes and didn't even have an account with them, set it up just for you :). Love all that you do and will review your AR 15 podcast soon. Also five stars. Wonderful stuff. Thanks for everything including reading my email. Good luck with the new podcast. Seems to be going well so far.

Bob:  About time! A excellent first episode. How often ?

Max: Hey Jake, I just wanted to say great show! I found your podcast last week and have found it to be very informative. I am experienced with the m4/ar15 platform from serving in the Marine Corps. Currently I am serving with 3rd Force Reconnaissance Co. 4th Marine Division. I have shared your podcast with my fellow marines and now we all look forward to your show every week. Due to financial restraints I still do not own a personal AR15, but hope to one day. Thanks for the great show.

Frank:  Have either of you used an ATI polymer AR lower? Also I would really like to see a truly barebones, rock bottom priced, but upgradable AR build Bryan Bolivar:  A point from your last AR-15 show.  The sproing is your rifles way of talking to you. A sproing means all is well, "shoot me again".  When you don't hear a sproing you know something is up. You either need to change to a fresh mag or complete an immediate action drill to get that rifle working again.  Embrace the sproing, don't try to silence it. This is advice I got from a retired Canadian Forces Warrant Officer. I've proven it to be true to myself in competition over the last couple of years.

Yancy:  Hey guys I mean zack and Steve. I could use a show on optics. How much, is it one of those thing that "you get what you pay for,  I too am in the process of building an ar. I a cheating a little by using a in good shape older A2 as the donor  now working on the different optics I can add. Think about running an small fixed power scope on the handle and then a red dot on the side.  Thanks for all you help and the check is in the mail! Paul:  I just finished listening to the first AR-15 podcast tonight.It was great!  Really informative, and the combo of guests you had really made for a great show.  A lot of what you guys are going over actually can apply to your most awesome listeners.........(Canucks) Larry:  Is there a way to download the ar-15 podcast to my ipod? I want to listen to it at work instead of over my computer. Also if you didn't talk about it in the first episode could you talk about converting the ar-15 over to the 300 blackout and what that is? I have only heard about doing it but know nothing of it. Thanks
