I use this one Bluntforce for those insane pins. But their are so many tools out their now to be counted to install. Damn back when I had guns ARs I bought xtra pins and springs cause they flew.

But that is a good one thank you.

I just do it inside a gallon ziplock bag with my trusty Old Timer pocketknife.

I hope I get over the compulsion to assemble any more.

For $10 this one is hard to beat.

I just built a lower yesterday. One of my springs took flight, but since I had a relatively clear workbench and aimed at the wall I had very little trouble finding it.

Built two a couple weeks ago, first front pin went smooth. Due to low light I didn’t see the roll pin for the mag catch was in the channel of the front pin and had a spring/detent launch like it was planned at Cape Canaveral. Also managed to lose one out the back due to a retarded approach to buffer tube attachment (hint: screw the fucker in then worry about the rear pin spring installation).

Took it to a local builder from whom I had to buy two pin springs, one pin spring detent and a buffer retainer detent and spring. Had to stake my own castle nuts because there’s an epidemic of disbelief in the necessity of staking the fuckers. I’ve had one back off. Fuck that shit thank you very much.

Don’t need to buy special tools for a build every two years or two builds a year... but I might anyway.

That commie queer Karl Kasarda and that lardass Russell Phagen are completely FOS advising people to eliminate the buffer retainer.

I'm going to help my "brother's"( from another mother) son build his AR soon. He's 21 and a good guy, just no gunsmithing experience.

I use a 6" SS metal ruler & a towel on the workbench to install that spring & pin. It works for all the pins on the AR lower. Haven't lost one with this method.

Front pin is the only difficult one. Needle nose pliers and a razor blade make it easy as pie.

BlackBelt · 10-20-2021, 02:24 PM

Like Travish, I just use a razor blade to hold the detent pin in while I push the pivot pin through.
Pretty easy and very cheap to do

Yup.

I use a drillbit to hold the detent pin in,slide the pin in behind it then rotate pin until it clicks in place.Easy as heck.Ive done it this way for the past 40 years.HTH eta use the end of the bit that is smooth and goes into the drill chuck.

That's pretty much my way, also.

Has anyone ever used a chronograph to test the speed of a flying detent pin once it busts loose from your AR? I am wild guessing at about 950 F.P.S.?
I had one hit the frig. bounce off a wall hit something metal then my cat screamed. Be damned it hit the poor guy in the head and went in his food bowl. Cat was o.k. and I got the pin before he could eat it.
But if someone could run their pin through a chrono could be interesting to get some speeds.
