Just completed a build last night. I lost 3 take down detent springs. hahaah. Such is life.
FOOT pounds. Not inch.
Just bought an AR, and did what any good operator of new mechanical doohickery would do — randomly twist things and experiment! Until something broke and my bolt wouldn't go into battery. Thankfully, this video showed me how to fix all of that and now it seems to be working again!
Always stake the castle nut.
couldn't the take down detent pin lodge into the hole in the take down pin and lock it up so you could not slid out the pin ?
The one design flaw of the AR, fucking stupid detent springs.
Good video.
Thank you for the making the video only 2 minutes long.
so what happens if I do not put the tiny take down spring? cause it will not stay when I put this on
Great video! very helpful
It's NEVER that easy
What is the detent spring for? Damn thing gets lost all the time
It needs to be torqued to 40 FOOT POUNDS not inch lbs.
40 INCH (not foot) Pounds…this is a much talked about subject and many broken parts have occurred due to misinformation on the internet…OR…Just use German engineering and snug it "gutentite", and either stake it or use a dab of blue loctite.
If you tight the buffer tube without a index support or pre-angled; most likely you will end up with a canted buffer tube.
40 ft-lbs, not in-lbs
How exactly can you measure 40 in/lbs with that wrench?
is it really only 40 inch pounds of torque at the end or foot pounds.
How did you keep the tube from spinning?
thanks sooo much!!!!
What about staking?
Where is that wrench from? I have a HUG Flight AR wrench that works good but is a bit fiddly, I sure do like the thickness and ease of the wrench used in this video.
this helped… thank you
thanks a lot! helped me out
thanks a lot! helped me out

Great video! Simple and the angle of the camera for each part was spot on.
Kalashnikov must have roared with laughter when he saw this.
This just saved me a lot of "WTF" I've been messing with for the last hour… thank you.
How do you tighten the castle nut without turning buffer tube? Having problems getting it straight.
what is the best mil spec buffer tube kit for the money.
I think i don't have the correct spring. Its to long. I can't mount like that
Now I have to wonder why it takes everybody else 15 min to do exactly the same thing.
does a ar-15 need a buffer retainer if so why
It's hard to tell what it is he's putting in the rifle. It's frustrating the detent looks just like a lot of similar parts. He needs to show each part up close before he installs it.
One of the worst parts of the AR15 design are all the tiny springs. When I put a collapsible stock on mine, Stag sent me takedown springs that were too long, but I did not realize until trying to press one onto the detent with the plate, which bent the end of the spring. This, in my mind, is not field acceptable. What if someone wants to use a fixed stock for long range but needs to go through all this rigamarole to do it?
You misunderstood my comment. I am not anti-gun. Mobieus7 made a comment that AR's are "friggin Lego guns", and I informed him that they are not.
Swimming pools kill more each year. Fatty foods and general obesity kill over 300K per year.
My AR15 has killed nothing but feral hogs and paper targets. I have burned lots of calories with it too.
The proper tool for the job is always best. In this case, it depends on if you want to keep your castle nut and buffer tube in good shape. The wrench will help to prevent mangling up the nut or the buffer tube threads with some other type of tool.
You really need that wrench? Any other way of getting that nut off? ….i have a Colt AR…
Get a KNS Precision Push Button TD pin. They're $16, and will not strip away any aluminum from the receiver, plus you never have to worry about the takedown spring ever again.
Good video very helpful
Actually building an AK is more difficult then building a AR. im finishing my AR as soon as the rest of my parts get in now they are more easier to find. An ak requires you to bend the flat as soon as its bent in any way it becomes a firearm, then you have to heat treat it spot weld the ejector rivet everything . i like ar becuse i used it alot and its very customizeable
Tried to find my spring which launched into the ceiling…searched for an hour in the garage…my wife walks in wearing socks and steps on the spring which got me back on track.
please help my take down detent spring got a bent on the end how ever i managed to get it all together.what does this spring do and what is it for any budy help please and ill sub to your channel
