Complete AR15 Owners Guide:
With the method we use you’ll need a vice, towel, and a 3/4″ wrench. Some muzzle devices will use shims instead of a crush washer. Make sure you’re getting the correct device for your specific threads. As always, do some good research before you get too crazy. Torque specs vary by device and manufacturer, however with most, if not all, the spec ranges from 15-30 ftlbs for 1/2×28 threads.

Great vid. Very helpful for my ruger pc carbine muzzle break install.
I was hoping I could get a little help brother – I recently got a Tikka T3X UPR , and then an AR-STONER Precision Muzzle Brake (it was only $20, figured it was worth a try…) – it's my first muzzle device. I thought I could remove them and install them just whenever I wanted, screwing it on and off etc. Obviously not. I guess I will be "installing" it semi-permanently – one of my questions is, how are you determining the torque you want/need to use, and then how are you measuring it? It looks like you're using a standard wrench and I can probably replicate the process, just not sure when I know I'm good enough or not good enough or waaaaaay too much etc. Thanks very much, it was helpful to watch definitely.
No matter what .. do a close up of your washer position since u are trying to demonstrate to an audience. VR mike. Master Armor
that "lube " on the threads will be carbonized by the intense heat of the barrel. Pretty sure i threads should be clean and dry,
I have the same Comp. I can't remember the name of it and there is no markings. Do you remember it? PS: I found it. It's a Spikes Tactical Comp.
Can you do it without the vice grip
Yes. No. Good. Bad. Do. Don't. Right . Wrong. You know what? I'm taking mine to a professional gunsmith, spend a little money and have it done RIGHT!!!
this helped! thank you
2 blocks of wood with a v notch cut and set in the vise are the best to use!
Man you really don't need to torque down so much on a crush washer, Its truly not even a washer snug it and index it your done, all that tightening backing off is not necessary, if your using a crush washer
If 20 pounds feet is required then bear in mind that that isn't that tight really. As an example the 'average' lug nut on a car is normally tightened to around 80 to 90 lb.ft.
That'll give yo an idea of how tight you should 'torque' it up to,..not that much really!
Who makes that comp
Guy sounds like a coke head with all the sniffling. lol
Doesn’t backing it off make the crush washer useless?
you do not tighten and back it off with a crush washer….thats why they are a one and replace
What part of japan were you in?
Nearly 170,000 views on this…SMH….LOL
Great video dude, one trick you might like to start using is instead of using a towel to wrap around the firearm in the vice, simply take your shirt off and wrap it around, then you can do a quality job on your firearm while getting some hot chicks at the same time.
got crush washers cheap under 3$ shipped https://www.ebay.com/itm/253880705562
HEY NUMB NUTS, EVER HERD OF SOFT JAWS
Thanks Gents!
That's exactly how you don't use a crush washer. You don't back it off and re tighten. That works on your barrel nut but not a crush washer. Why do you think they tell you they are a one and done deal? You can easily get 360 degree rotation on the nut to tighten and time it correctly. Maybe not if you're using a towel to hold in the vise though.
Tight and then back off? Way to teach us how to ruin a crush washer
You know for like 25 bucks you can get a really nifty tool that allows you to do this correctly. Instead of clipping your gun in a vice with a towel.

I like the sticker on the tool box #okinawa
+Highjak86 Thanks for the demo guys. I'm getting rid of my birdcages and going with something a little more "flashy"… no pun intended. I have no objections to the towel, despite my fellow gunners below questioning it. It works.
All these guys going off about the towel , you are probably fine.. that being said if you have any kind of shop drill a hole through a block slightly smaller than your barrel and cut the block in half down the middle of the hole. Not fancy but it is def spreads out the force over the surface of the barrel instead of crushing it potentially.
I just used a vise grip and a impact wrench.
I used a belt sander on my crush washer Just sanded it a Little at a time till it timed out perfect. Easy. I bought the shins and even bought silicon o rings. Couldn't wait I waisted money. Belt sander is too easy.
