No their not. They use QPQ which is basically a melonite corrosion resistant process. It is superior to chrome lining against wear and corrosion. It seems much of the AR and AK industry is headed this way. More on it here. https://en.m.wikipedia.org/wiki/Quench_polish_quench
Yup, I really like the new Melonite/QPQ stuff.
First AR was an Adams Arms AA15 with the Melonited 1:7 VooDoo barrel. I love that barrel with a passion.
I would go melonite over chroming nowadays, but all my chrome barrels have been on of other platforms.
I don’t truly know the hardness/wear resistance between them both, however.
I just placed an order with you guys to finish a lower receiver parts kit, thanks for the discount.
Thank you for the info.
Looks like we’re going to get it done. Just give me a while to get some rounds through it for a decent report of the performance 
First: Welcome SOLGW!
Second:
Awesome to hear! Will be watching for it to come through on my subscriber feed.
When Hannibal approves, you know you’ve done good.
Looks like a legit review coming for a legit manufacturer. I’m looking forward to it. I’ll be sure to keep solgw in mind for upcoming builds, sounds like you guys are serious. I like that.
coupon code doesn’t seem to be working
Just renewed the M4C discount code.
Didn’t realize it reset at the end of the month.
Thanks,
Mike

Just ordered a couple of Springco buffer springs from you guys.
Well, the M4-SML as arrived for the review. First impressions are that all the “little details” are perfect; the fit is as good as any I’ve seen.
Snapped some quick pics but it’ll on the range this weekend for the beginning of the real evaluation.
Is the castle nut staked? My cousin bought one a few months ago and was showing it to me and that’s the first thing I noticed. I didn’t look at the carrier staking but yours looks good.
I’ll let MrGunsandGear confirm this…but aggressive staking on the castle nut and gas key is critical and one of things beaten in to our armorers.
Every rifle that leaves here will be staked, so I’ll assume this one is too.
It’s actually staked in 2x places.
Next time I see him I’ll look at the bcg to see if it’s staked. I just didn’t want to start “taking it apart” because he is the type that would freak out.
Maybe he changed the castle nut and end plate for some reason.
His is a basic version with a fsb and fde magpul furniture. I do not remember what end plate it had or if it was a QD. It did just have a basic charging handle.
Then, that’s not a factory gun.
Everyone of our armorers must work as an intern for a few months before we ever turn them loose…and we have several redundancy points of inspection before a gun leaves. Staking is actually one of the ways we identify our rifles as being a factory gun. When I say it’s beaten into our guys, I’m being serious. It’s one of things that separates a good company from trash peddlers.
Same with barrel dimpling, thread treatments etc…
Running well so far!
Still going strong. Shot a bunch of different rounds through it yesterday for 5 shot groups. All, even range ammo, were sub 2’’ and most much better.
Cool! Looking forward to your video review. Out of curiosity, what is your typical ratio of filming to video length? I’m guessing you put a lot of video together and edit the heck out of it to end up with your final reviews. The quality of your reviews is obvious, and appreciated for sure.
