Aero Precision M4E1 Upper and Build Kit [Review]

Did you build your own evil, video-demonitizing rifle – or buy it straight off the shelf? Post up! 😎

I love you guys website and channel extremely informative!!

Keep your hand off the magazine when firing….

Is the gas block pinned or does it use set screws?

The money you guys have is amazing. How can you sustain buying so many guns?

2:40 – Yep…gotta have that whisk for my early morning omelette before my build LOL.

I have built a few ARs from Aero precision on 80% lower. I break mine in wet. And then fire a couple hundred rounds through it dry simulating a Grab into action situation. All their parts fit extremely well with high precision. 2 out of 5 Chambers are a little tighter than others. And will not allow the installation of a 22 long rifle conversion kits. From the 8 and 1/2 inch barrel pistol to the 20 in Barrel rifle they are all extremely reliable an above-average in accuracy

WET! and run it like a 50 cent whore!

I just built a new Aero M4E1 pistol and it only took me 45 minutes to assemble!!! Those allen set screws on the bolt release and rear take down pin are MONEY!!! Such a time saver and no pins to concern with on the trigger guard. Can’t beat it!

When I got my first AR I babied it for a while before I started to learn about the AR and it's capabilities. So when I got my PSA 10.5" AR pistol, the first range session was 600 rounds and I first did a couple mag dumps, then I sighted my irons and red dot in. Then I ran her hard until I ran out of ammo. I also only apply a little oil to the trigger assembly and a touch of grease within the bcg and left the rest dry…after my range session I managed to blow 2 of the gas rings on the bolt….replaced then with a JP enterprise 1 piece gas ring set and since then over another 500 rounds with no issue. Haven't lubed or cleaned the bcg since, if anything I just run a bore snake down the barrel and do a quick wipe down with an old sock on the bcg to remove the metal flakes from the primers and such. I also always do a function test with at least 5 rounds when I'm done to ensure proper function since I use my AR pistol as my home defense weapon.

Love the M4E1 sets. I sat on mine for months waiting for the ATLAS R-one.
Break in?
Not with a nitride or chrome lined barrel.

I have to run my rifles wet because I hate the feel of a dry rifle. But I do just sling the rounds right down range. No babying here. 3 shots to zero and then I shoot until I'm tired

I'm not a fan of breaking in any rifle. What I do with a new build after a function check I will load a mag with one round to make sure it locks open. Then two rounds and then three to check for proper function. After that I will start loading mags and having fun. I usually run mine pretty wet with a healthy dose of CLP.

I love my Aero build. They make one of the best charging handles

I'm in the process of building a Aero Precision M4E1 inhanced upper and lower 14.5 rifle. But when I break in a new rifle or barrel I run it wet and after 1 30 round mag I'll run a bore brush through the barrel a couple of times, then I will shoot another mag and clean the barrel one last time. Then I shoot the crap out if it.

What does chromoly lined mean?

I like em wet

Aero makes good stuff!
😍
Wish they would bring their camo dipped receivers/handguard kits back on Brownells!

I love the way their handguards line up with their upper receivers. Nice and straight!

My first build was with an Aero Precision upper and bcg with a Spikes Unicorn lower. I call it my Unicorn AR. It's truly mystical with pinks and blues and a 5.56 1/8 twist stainless fluted barrel with a Troy Medieval muzzle break. It's definitely a rifle made for conversation and fun at the range.

I say lather up and let er' rip tater chip!

First, I recommend adding a BCM Mod 3 vertical grip. As for how I run my ARs, I just shove anything down the pipe with minimal amount of lube and virtually no deep cleaning until hundreds of rounds have been sent down range. Bear Creek Arsenal and Anderson Manufacturing for the win!

I run my AR wet, and break it in slowly.

New Ar15? Just lube it and abuse it.

Hey Johnny, is that egg beater metric or standard?

I've built 15 ar's. First run oiled and 500+ round. Need to put 2000 round b4 ur ready

Two thumbs up 👍👍 on doing an initial thorough cleaning. I usually do a modest (light coat) of lube following cleaning. Keep in mind that I typically have NiB BCG, M4 ramps and chamber. My planned regiment (although it's subject to changes) is escalating. First time is 30 rounds with a rough sighting followed by cleaning, thorough inspecting, and modest relubrication. Next is 60 rounds with repeating the aforementioned with a little more attention to sighting then 90 rounds repeating the aforementioned. Next comes the big day of 120 rounds with really fine tuning the sights followed by the aforementioned. At this point my plan is to step back the thorough cleaning and inspection to every 600 rounds but do a light cleaning, quick inspection, and modest lubrication following every outing, regardless of the number of rounds fired (I don't have an ammo provider or reload so it usually won't be more than 120). Each trip to the range begins with sighting confirmation. Unless it radically shifts then I don't concern myself with it but keep a note of what happened. I really recommend keeping a log book on each gun you own and what it is doing as well as what you have done to it. It seems like a lot of effort but it can pay off for you in the long run.

Looks great….. the FDE is growing on me……

feed it and run….

BTW: Perfecto mundo means perfect world.

How does one convert acorn squash to the more standard banana ????

Slick it up with CLP, check the bore, then mag dump to my hearts content

LOVE me some Aero Precision! I just built a Aero lower and bought a Palmetto upper based on your recommendation! Great shooter!

I've owed an Aero for over a decade, can't speak highly enough about their rifles

I'm planning a 300 Blackout pistol build- after watching this, I think I'll start with an M4E1 lower.

Wooooo!!
