This is the fifth video of a series following me building an AR-308 on a budget and shows me install a Ballistic Advantage barrel and a UTG handguard.
Here is the link of my video showing how I dimpled the barrel:
The AR is DPMS format and the series follows me building it part by part from the stripped receivers to the completed project. In this video, I show how to install the barrel, handguard, gas tube and gas block. I hope you enjoy!

I never understood the idea of tourqing and loosening the barrel nut 3 times. As an aircraft mechanic, we only tourque fasteners once. Tourque specs already factor in fastener stretch.
Good Video..Your only the 2nd person Ive watched that had enough snap/knowledge to put the wrench on torque wrench correctly. Thumbs Up Brother.
I’m looking at building something similar with 16” barrel, I’m going to add a suppressor eventually. Would you recommend a rifle length gas tube? Or getting an adjustable gas block? This is my first build and trying to avoid common mistakes. Thanks!
should you not be putting dimple, after you have installed gas tube, handgaurd, barrel nut, so that you know where exactly the dimple is needed?
Lap your upper receiver, and you won't need the barrel nut shims.
A trick to make installing a free floating handguard a little easier is to heat the end that is slipping over the mounting ring with a hair dryer for about a minute or so, The metal will expend just a bit and it will make it easier to go on.
Did the UTG handguard match precisely with the M5 upper tang?
These videos have been a tremendous help to me…thank you!
You lost me on that fucking barrel.
There was a sale for an AR10 lower and upper set for $99 at my local turners store last week. Would have been great to start a low budget and now I'm encouraged to do one.
What size drive is the torque wrench. I could have sworn I heard you say what size it was but I can't find it in your vid lol. Ordered my 15inch rail. Can't wait to get it.
You thought you were slick with the threaded rail nut editing it after the glass block huh lol plus you forgot to mention the different rails out there specifically 308 have low or high profile. This rifle is a dpms build high profile. An AR10 would be arlamalite low profile.
Don't you feel it is necessary to drill a taper pin into the gas block and secure it to the barrel?
What length gas tube did you use? I'm looking at a DPMS gas tube on midwayusa.com but i don't know what length to get. New to building AR's so sorry if its a newb question lol.
What type of vice block did you use that is compatible with the aero upper?
Stupid question, im having a really hard time ordering my handguard. I have the same upper as you, I wanted to go with an Aero handguard but would I choose Aero/DPMS or Armalite? Im going with a DPMS SASS barrel if that helps…
Torquing down the barrel, is there a plus or minus on the torque? Or just 35 lbft. Wondering how much stretching is allowed or figured in to the torque. You had said torque 3 times total. I have been assembling aircraft components most of my working life, there is usually a range. Later in the video you had mention the possibility of torquing slightly higher for alignment if needed. In cases where we used a castellated nut with a washer and a tab you bent over, you would start with the lower end of the range so if there was adjustment needed you could tighten higher without over torquing.
Did the gunsmith have to do anything with the headspace?
Did you have to headspace your bolt?
is there any way you could leave a link to the handguard you used?
Would have loved to see how to dimple the barrel
What's ur barrel length
Awesome videos man! Good angles and lighting. You spoke clearly and there wasn't a time where I was confused with the whole series. I will definitely be watching your videos over when I build my AR-10! Subscribed.
