How to Install an AR-15 Hammer & Trigger Assembly Presented by Larry Potterfield of MidwayUSA

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!

8.5 lbs lol. Woot

Thanks for the waste of time

Fr dude wtf

trash video

The Brownells video is easier to follow with less fingers in the way

You can hold the hammer with your palm and dry fire allowing the hammer to come back easy.

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.

Dang! I've been doing wrong. I've never used my receiver block, and I've always put my pins in from the right without a slave pin.😅

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.

What are we supposed to look at? Lmao what a waste

It would be nice if the video actually showed something besides his hands.....

Terrible viedo

Just stop giving money to the NRA, they are anti gun.

Thank you Mr Porterfield. This was a big help.

I assume the safety selector is not needed😂😂😂

Excellent and informative video! Thank you!

if you cant follow along to this you shouldn't be building a sandwich let alone a firearm

This video sucks. Slow down and show more.

Thank you for this video. I didn't have temporary slave pins, or a vice, but not difficult at all to reassemble it all with the help of this video.

Fingers ......

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.

waste of a video, didnt show the hammer spring

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.

This video lacks all the important details people use these videos for lol

She was shot by one of her own 99% of all cop shootings is from their own partner

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.

Thanks for blocking what could be useful views.

Can't see anything... which direction do the trigger pins go in?

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.

really poor instructions on the hammer assembly. Legs of the spring on the pin? thats it? how about some video on it?

Does anyone have an extra pair of these they are willing to gave away

Voo this video

You can’t see half the install this is booty

What a useless video

Here’s a view of my hand while I work behind it

This is a really bad video

Absolute worst video ever. Basically not helpful at all. No shot of the trigger spring in an installed position. No shot of the hammer spring at all. The images that were shown that you might be able to infer about looked like a person with Parkinson’s holding the parts. I got mine working b/c I had done it before just needed a refresher but a newbie can forget about learning anything from this video.

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

Let’s also not tell people that you need to install the safety first or you have to take everything out and do it all over

thank you,

I’m pretty sure this is the worst install video I’ve ever seen in my life

Useless

Move your grubby paws couldn't see anything.

Where or how do I make a slave pin? My build didn’t come with one.

Can't see what you doing with the hammer
