For anyone doing this for the first time, here’s my advice: buy at least one extra Aero parts/“Fix-It” kits. Once that front detent goes flying you aren’t getting it back.

Great video, clear step by step, many thanks! 2 suggestions: I managed to lose BOTH of my takeout detent pins as they went flying off to... wherever. Managed to get replacements pretty quickly and decided not to be stupid again, so got a large box, lined it with a towel, pointed the detent and spring INTO the box as I put it in. Caught the first one before I finally managed to get it in place. Also used the credit card trick one of your other viewers mentioned below. Other suggestion: YT is gonna nab you for "how to assemble a rifle" vids. Strongly suggest you duplicate over on that competitive channel.

5:34 I use a 1/4" clevis pin. It looks just like a takedown pin but it has holes in it. You feed your spring and detent through the hole, press it in with your Allen wrench and turn it until it's locked. Set the takedown pin flush against the clevis pin and push it through. Super easy.

@Tilt_TM 7 күн бұрын

Just a PSA, Aero actually recommends cutting the takedown pin's detent spring down a bit because the set screw takes up some of the space inside the channel that would've otherwise been occupied by the spring.

Patience is key. I lost my first detent. I found a 1/4 drill bit works perfectly, similarly to what he used the screw driver for(the chuck end of the bit not the drill tip). Transferring from the drill bit, that holds down the detent, to the takedown pin was super easy.

At 9:42, if you have trouble pushing out the rear takedown after install, Aero Precision instructs to cut a few coils off the spring with a cable cutter. Leave it full length if you don't have a 4-40 set screw and this gets captured by the buffer lock plate

Nother tip, I used a spark plug gap tool on detent, similar to the credit card tip below - used the .025 fin to hold the detent down with one hand while pushing the pin through with the other, then just slide out the gap fin (receiver upside down in vise made it a lot easier though)

1/4 x 2” clevis pin - about $2 at Tractor Supply. Get the one that has holes all the way down the pin. Push the clevis pin into the pivot pin hole from the left side of the lower. Align the hole in the end of the clevis pin with the pivot pin spring/detent hole. Drop your spring and detent pin through the clevis pin & into the hole in the lower. Push the detent pin in with a punch/hex key & rotate the clevis pin 90 degrees. This will hold the detent in place. Now you can perform the “switch-a-roo” maneuver as described in the video.

Should I just buy the PSA kit with the upper and just buy the screws separately and have some extra parts from PSA? Also does that screw by the bolt catch come already installed on the reciever or did that come with the parts kit and you installed it before the vid?
