Brownells Gun Tech™ Caleb Savant shows us step-by-step how to install a Midwest Industries G4 M-LOK® AR-15 handguard. Good news: it’s an easy process. The G4 typically comes out of the box with the barrel nut, spacer, and screws installed. You’ll have to remove them before you put it on the rifle. Is the barrel nut stuck in the handguard? Watch Caleb’s simple trick for extricating it. Now, install the barrel into the upper receiver. Don’t forget the lube! (Caleb’s using Brownells Action Lube Plus®.) A little lube on the barrel nut threads AND on the face of the barrel extension then… Screw on the barrel nut and hand tighten it. Put the included barrel nut wrench on your adjustable torque driver and tighten it up to a little more than 35 ft.-lbs. (Recommended range for an AR-15 barrel nut is 35 to 85 ft.-lbs.) Install your gas block / gas tube assembly. For a test fit, slide on the handguard, lining up the anti-rotation tabs with the upper receiver. Then remove to install the spacer. The spacer goes in only one way, AND Caleb has a tip for checking to be totally sure it’s in correctly. Slide the handguard on for good, and torque down the screws to secure it. Install your muzzle device and bolt / carrier group…. And you’re ready to mount accessories on your new Midwest Industries G4 M-LOK® handguard!

Brownells Wrenchman handguard in FDE when?!?!
Curiosity. What is the barrel? Looks like a lightweight at least, maybe described as even a pencil.
How do you know the gas block is properly aligned with the gas port?
I am curious as to why not set the gas block screws to a specific torque setting or use a low/easy set break lock tight?
Shouldn't your torque wrench be at 90 degrees of your barrel wrench?
Thanks

Just curious: I noticed that you did not Torque and then remove the barrel nut multiple times, is it not necessary to season the threads on the barrel nut?
Already been said but this why I like this channel, and you know here in south Louisiana we measure jobs by beers 🍻 that a let one start to get warm or 2 quick cold ones 👍💪🇺🇸🇺🇸🇺🇸🇺🇸
I noticed you did not tighten barrel nut and then loossen two to three times and then torque to 35 to 80 lbs. Is this not necessary.
Excellent video … short and to the point.
Question. Does the alignment of the torque wrench to the barrel nut wrench have any effect on the amount of torque delivered (ie inline vs 90 degree)? I have been told the torque wrench should be at a 90 degree angle to the barrel wrench. Another myth?
I have no idea what length I need for a 16" barrel, and the web site doesn't help. (They are out of stock anyway.)
Good stuff. Always learn something!
I got a new pistol length gas tube and its for a 300blk supersonic 16" barrel can I change the gas tube for a longer one?
does that lube change torque values or is 'wet torque' implied here?
this is why i like this channel.
a simple, direct demonstration. no editorializing, no excessive babble
meant to make the host look like some super guru. just the tutorial.
the smyth busters segments and these tutorials are the gold standard
of learning about armaments on youtube. let's hope they're left alone
by the fickle lords of woke at google/youtube corporate.
Midwest has good stuff, no?
Thank you sir!
I have the Midwest Industries 15in combat Mlok rail. Very sturdy and durable.
Hm so if I have a slip ring that holds my handguard in place, it looks like this handguard is totally incompatible with my setup. How would I know if a handguard is compatible with the slip ring and corresponding ring of plastic toward the front of my barrel? I can easily take my handguard itself off for cleaning using the Delta Ring Tool. But if I want to upgrade my handguard entirely does the slip ring need to be adjusted or swapped out? Is there an AR-15 standard spec for this?
Always perfect videos thank you
Outstanding tutorial Caleb, oh and your hair looks really good today!!!
Midwest makes good products, especially for the price.
Dapper Dan at it again.
