DIY: AR15 Lower assembly tool.. Watch and learn – It doesn't have to suck!!

For all these years, I've been doing it the hard way – with my left thumb nail and a razor blade. The nail to push the detent down, then the blade to hold it until I got the pivot pin in place. I never lost a detent, but your tool looks so much easier to use.

Might end up making one (or two) of these. Started on a lower yesterday and just used a box cutter blade to hold the detent down while I pushed the pin in. Was quick and easy, though not as "elegant" as either the Wheeler tool or this homebrew solution. Still a worthwhile video. Keep it up. 👍🏻

I just use a small snap on screwdriver that came free with the purchase of a toolbox and a pair of needle nose pliers wrapped in tape for my builds, everything else aside from the castle nut on a carbine buffer tube or the grip screw is a hands assembled operation

As a retired Harley mechanic , not a tech !! (16 years now) I made a bunch of "specialty tools" to get the job done correctly and efficiently. I guess I'm getting lazy any more because I was just about to coder this tool. I Built my first AR about a year ago and sure could have used it. Thanks for the Idea and I will be watching your pomputer TV shows and following ya on the face page (when the grand kids show me the buttons again). any how, grind it ta fit and paint it ta mach and for goodness sake keep the shinny side up.

1/4" clevis pin from local hardware store works too,,, that's what I used for 4 of my builds

Good lord that easy and have been fighting for years. I Like the Nylon part because it will not mar or scratch, Now give me easy way to install bolt release without out
dings and scratches and the reast is easy
peezy

i just use VA ID card or any other ID card to hold everything down slide that front pin in its not rocket science, but hey great video thank you

This is nuts, just go to Rural King and buy a bag of 1/4" pit pins.  They are used with cotter keys or push pins, mostly found on farm equipment.

$.69 Clevis pin from Home Depot works great

Good trick. We just used a 1/4 "  Clevis pin.  It worked great.  Thanks for the new trick.

good stuff there sir

I use a 1/4" clevis pin. $1.50 at ace hardware.

or just use a magnet lol you get one with every battle arms development ambi selector.
any small magnet works. they came up with a pretty nifty idea.

Do you believe in Bigfoot?

you sick genius yoy. cool

Thanks Mark……

Or you could just buy a 1/4 x 2 clevis pin for $1.13 and be done.

just but a 1/4 inch carriage bolt for a buck no drilling works fine

Gotta love that mall music.

I like cheap, nice job

I just use a razor blade it works fine.

I always screw up this part, but I tell myself the sticky roll pin adds character. You guys need to get back to shooting things and torture tests. The weather is nice!

i'll give yeah 3 dollars for it..lol

Hmmmm…Why didn't MacSalty think of that?

great idea mark!!

I made one out of a brass rod I had, wish I had thought of the plastic bolt!! great video!

1/4" clevis pin will do the same thing. Costs the same and you don't have to fool with drilling a hole.

1/4" Clevis pin is easy to find and perfect for this application

Totally worth it. I've had one for years.

i so love your CNC machine and Polish machine! i so have to get them both at Sears Hardware tomorrow. seriously great job on the video and the Tool to help us all out for cheep! keep them coming.

Interesting little DIY tool. May look into it. In all my previous builds I've just used a razor blade to compress the spring and detent while I insert the take down pin. Easy enough and haven't had a spring or detent fly.

Clevis pin from Menards for around a dollar or less and have someone hold up a trash bag and install the pin inside the bag. The trash bag has saved me a ton of times.

I bought the tool and a 8 inch wide magnet on a stick , when the pin goes flying just " sweep" the floor and you'll find it fast !

Also amazon had that tool on special for less the 10 bucks and free shipping.

I like the background music. It reminded me of old porn movies I used to watch.

As a gunsmith your answer is cheap and simple I would have used brass stock for the tool and blued steel for a grip handle I normally use brass and steel for tools as it helps to make special tool more visible in a tool box and on the bench. Also it help to control walking tools.

I just use a two-pack of Hillman 1/4" clevis pins (at Lowes?), for about $2. They are steel, and have a row of small holes drilled already drilled into them. Just make sure any clevis pins you buy are long enough to span the width of the AR lower..

I liked the touch of the DIY pivot tool porn music while sanding the shaft and checking the fitting…

I just bought my first stripped lower yesterday….destiny?
