Everyone asks where I find AR-15 stuff in stock or where I order from, so here you are:

In this video I show you how I install a muzzle device – a flash hider in this case – onto an AR-15 barrel. The tool I am using to install it is the Hammer Head Tool.

  1. WARNING: anyone doing this, you MUST lock your barrel from turning while doing this. otherwise you can end up turning your barrel, breaking the pin holding it place and knocking your barrel out of alignment which will almost certainly end in a catastrophic failure. Not fun when your bcg releases at 60,000 PSI. You won't have a good time.

  2. I use nickel antiseize compound because AerosSell SUCKS! Valvoline's top tier Palladium car grease is better than AeroShell 33. AerosHell would melt in an E-Z Bake Oven, but nickel antiseize will not melt until your barrel has warped. It's fail temp is north o f2100 degrees F.

  3. My crush washer seemed to flatten wider than the muzzle brake which I haven't seen before. I don't know why it did that. Also it seems to not be centered, it's more to the right than left as well.
    Do you know why it did that?

  4. Over-tightened my VG6 Epsilon a hair and discovered the hard way that this affects targeting. Want to back off a bit, but am now concerned that this will free up the tension on the crush washer too much.

  5. Does the crush washer become swagged to the barrel or can it be removed and replaced for another muzzle device. I have a muzzle brake that appears to need to rotate almost a full turn. Will a crush washer crush that much?

  7. +nsz85 Thank you for posting this. It's easier than I thought, but it's always nice to see someone else do it first. I bought some DPMS flash hiders, just for the aesthetics. Perhaps I'll add a comp-device one day. Much appreciated, and I am a subscriber. Your videos are super!

  8. So glad I found this video,,, I mounted mine 3 times with the crush washer Bass Akwards,,, the other 3 was test fitting a borrowed can to see how it lines up.
    I Also use Blue Loc Tight for that Little extra security

  9. hey bud sorry about a rude comment I made in another one of your videos. I was having under gassing problems with a hand cut 18 inch carbon fiber barrel and a  seekings adj. gas block . and I don't have any real gunsmiths for hours from my location . and you commented their called gunsmiths . I know bud I usually do all the work myself. I just drilled out the port 1/64 inch bigger. seems to be fixed . sorry for that comment . and I do like most of your vids
