Watch as Larry Potterfield, Founder and CEO of MidwayUSA, presents “The Hammer and Trigger Assembly" in the How to Series, Gunsmithing the AR-15. For this and other MidwayUSA videos visit the MidwayUSA Video Library: www.midwayusa....
99% of the people watching this didn't learn anything... You need to show how the hammer spring legs get bent backwards almost 180° and sit on the trigger pin while you fight the hammer in.
@@TripAMD I agree it could of been explained more but the video is still good and so far yeah because I did it all last night and even had a different lower kit. Other than the lower being out of spec or the trigger being to fall was my only problem
@@travenstevens6001. Did you get it all together in the end? Sometimes you gotta lightly file down the burs around the flat side of the safety selector. It also goes in before the pistol grip or it won't fit. What brand lower are you using? Andersons can be a little funny sometimes, thats why im asking.
Not really a install video but a great assembly video. Made sure my hammer, trigger and trigger spring were facing the right direction just like demonstrated in the video. I used common sense for the installation and was able to take apart and install two triggers for my rifles 💯 thanks for the vid
Thank you. I took apart a trigger assembly and paid attention to the layout and detail, the standard of triage or troubleshooting. It became excruciatingly clear that Eugene Stoner had a mind like a steel trap and that I would be putting back together something so deceptively simple. After wards, I felt as if I understood my weapon in a complete level of detail that would allow me to advance my learning and begin purchasing the unnecessary yet highly advantageous tools where I could call myself an armorer of said system. That little pin, gosh darn that makes it so much easier.
Let's make sure our fingers obscure any useful views of the only challenging part of a lower build! Yeah - and maybe we can hurry through it to really keep our audience guessing! Lol. I feel like I've been Brownelled.
Every time I I build a lower regardless of how many times I've done it I always look at these videos. Thank you, Mr. Potter. It truly is a wonderful life, Geo. Bailey!
Should we show how the springs assemble? Midway: nah, let's just make it as confusing as possible and show almost nothing. Oh and if boss man can keep his hands covering the important stuff, that'll make it even better.
Thank you for this video it really helps to be able to understand how to install the trigger and everything in to the lower I received the whole AR 9 build kit from SDI the AR 9 build kit is made by panther arms and the way the trigger goes Into the lower in this video is exactly how the trigger goes in my AR 9 lower.
This was my first lower receiver build. I have replaced several triggers with single stage modules. I have watched several other videos on the lower receiver to see trigger install. I did have to watch the part of installing the hammer three times to catch spring positioning. Any improvements suggestions would be to stop and include a good look inside housing showing spring placement. Thank you
Thanks was a big help to me . Some of the camera angles could have shown more like the legs on the spring. you did say they rested on the pin that was good enough for me.
Fat end up on disconnect spring. The spring gets bound up with fat end down. It will still pivot but you can feel it catching with your finger. Also.. look closely, the "toe" on the sear won't ride inside skinny end as it should. Only fits fat end.
The hammer and trigger pins are the same. 3 grooves. Two end grooves for hammer spring legs to lay in and keep trigger in from walking out. Center groove for hammer, little spring leg inside the hammer hole, keeps hammer pin from walking out. Safety/selector goes in first where it interacts with the trigger and disconnector assembly. Can not install safety after trigger. Safety, trigger, hammer, in that order.
nah, that's getting the trigger pin through the sides, then through the hole in Sear. You have to line up a hole under spring pressure on part that is fighting different spring forces. Without a drift pin guide, it can be were those missile detent on the Pivot Pin , which you should do inside clear bag, so if they try to go flying they are caught in the bag. Making easy to find. Getting the hammer spring on backwards is very common and easy to mistake but easily fixed
As a gunsmith student I just wreck my brain until I notice something you can’t install FCG without installing safety switch it’s a big part of helping align the roll pins for trigger and disconnector.
You are correct.I waited to install the safety until after I put the trigger and hammer in on a AR 10 build.After a brief moment of panic I thought I was going to have to take the hammer and trigger back out.(I had a hell of a time getting the trigger pin in and I sure didn't want to take it back out)but I tried cocking the hammer back and the safety selector went right in.Whew!@@cgibsoniii1
Just wanted to say that when he says/shows placing the disconnector into the channel of the trigger, that is the WRONG thing/way to do this. MUCH easier to put the springed trigger down into the lower and THEN after placing the slave pin in from one side and the cross pin in from the other side (leaving just enough open space - width of the disconnector - between the slave pin and the cross pin) to then place the hole of the disconnector down into the trigger channel right into the small open space between the ends of the slave pin and the cross pin and then all you have to do is push the cross pin thru with your finger (note, no hammer or anything else needed) and that cross pin will slide across the small opening and thru to the other side of the lower receiver just as slick as a whistle !!!
Good video except for the trigger/hammer assembly section. All we can see is fingers and the part is being moved around so fast it's hard to see what's going on. Suggest holding the part up for a few seconds to show what things should look like after each step on the next one.
I'm no pro but listen closely to the verbal instruction. Think about what part is under spring tension and then replicate that. It would help to see it, yes, but he explains what the camera angles don't. When it came apart I thought it would be a bitch to reassemble, but it's not as bad as removing an A2 gas block. Also I dry fire a lower all the time, oops.
Too fast, too few a views of the assemblies and the installation of the fire control components into the lower. The tutorial should have been around 8 -10 minutes and not rushed at < 4 minutes! Graded as a D+ only.
@@vintageguitarz1 Why do you want any of that? It's 2 springs and a couple of parts held in with pins; just make sure the sure the springs are the right way round and slam it together. There are dozens if not hundreds of other videos showing the same procedure, go watch them instead of wasting time yapping at people in the comments. I don't know why you're not giving that feedback to Midway, instead addressing it to me when I clearly disagree with your assertions anyway.
Pins from the left to the right, un-grooved ends first... I'm always worried about putting the pins in correctly. The grooves are shifted on the pins, I think I get what he's saying...
I don't know what everyone is complaining about, even with the fingers in the way he showed enough to figure it out. Maybe you shouldn't be building a rifle if you can't figure it out from this video?
Probably newbies or people that won't take the time to learn and will take it to a gunsmith for a cleaning or detail strip that can be done at home. If you do it enough times, you will know by memory what each part is and where it goes.
in regard to the trigger and hammer pins..does it really make any difference which end goes in first?..or from which side/direction?..i am going to do my first build.
Professional I believe at one time I may have mattered. I myself looked at the assembly and do not see any reason it can’t go either way. Only reason you start with smooth part first is less friction when driving it in.
It doesn't. The hammer pin has a groove in the middle and on the trigger pin it's at the end. The hammer has an internal spring that sits in the channel of the hammer pin and one of the two hammer spring legs on either side will seat in the channel of the trigger pin, to keep them from walking out. If both pins are the same, with cuts at the ends and middle, it makes even less of a difference.
Getting very frustrated at the moment because I do not have a slave pin so I can’t get the trigger and the spring to hold itself while I put it in the lowet
Let's not bother with describing the parts so you will know what we are talking about. Which way is the front on the doohickey so I can put the open side of the watchimicallit facing the front.
Im almost 100% he oriented the disconnecter spring the wrong way… I’ve “built” my fair share of lowers and unless I’m doing it wrong… the wide end of the spring goes facing up not down. And if I am wrong… years later no malfunction to speak of. The spring should naturally fit, if you put the wide end down first, there’s some resistance… because it doesn’t fit at all. This video isn’t for starters and a “slave” pin isn’t necessary (neither is a vice block) but makes life easier. If it’s your first time… ignore this video.
Make sure you don't include any useful images to show orientation of the springs and make sure you have your fingers in the way and use a useless angle to illustrate the assembled parts.
ive built about 10 ARs to this video, Without a vice just a hammer and punch set. It helps to know how to put the spring on the trigger. This video doesn't help with that.
After more than a minute of watching…..I knew this was not a replacement video. Totally mis labeled and not even a how to on trigger replacement.

*Midway AMMO PRICE GOUGING USA!* Right now Midway USA is price gouging all ammunition when Americans are scared due to the corona virus and police saying they will NOT respond to theft or burglary calls. Midway USA is selling 30-30 WIN for $3 per round and 5.56MM at $2.89 per round. Capitalize on Americans' FEAR? Should you STAY in business??? Let's ask the rest of the Gun Community.
These AR Stoner trigger assemblies SUCK!!!! Mine will fire if the hammer only goes down one click - bottom notch engaging - but if it goes all the way down, which it will do EVERY time you cock it with the upper on, then the hook on the disengage hooks over the lower hook of the hammer and WILL NOT FIRE!!! Ihave to take a small drift pin to push down on the back of the disengage to get it to go back to the first position. And, YES, EVERYTHING IS INSTALLED CORRECTLY. I found another video that shows how to do it in detail right here on RU-vid.
Yeah, bad video, half the content is missing. Extremely fast, no clear explanation. Causes more confusion than anything. I’ve built over 20 and this video was a test and it failed. Miserably.
..............................yeah, not very good for newbies. need more eyes on inside view., please show what you are talking about.................................................
Been buying from midway since they sent out post cards many years ago. have built probably 10 ar 15s for myself, friends and family, probably 1 year apart. This video beyond terrible. trying to orient the trigger spring correctly. video a disaster. funny, bought my parts from optic planet. video needs pulled from youtube .
