80% Raw Lower Receiver Forged by Cerro w/ Safety Engraving Option

The 80% AR-15 Lower Receiver is NOT an FFL item. These units are forged by Cerro, which produces the forgings for companies such as Colt, Spikes Tactical Daniel Defense, DPMS and other major manufacturers. The ATF classifies these units as non-firearms. These units are “finished in the white”, tumbled and are ready to be bead blasted before either Anodizing or Cerakote finishing.

Specs:

80% Machined (Just needs trigger and safety well machined)
7075 Aluminum
T6 Heat Treated
Magwells are flared and broached
Cerro Forge (KeyHole)

Product Code: 80RAW-1

I had 2 out of 3 lowers i ordered that were Cerro forged and had tolerance issues in the rear pin pocket and the slope for the buffer tube to upper that made too much contact.Lowers are fixed but beware!

Remember when you cerakote most painters write it in their ATF book. Not to mention all your CC transactions are monitored anyway.

FYI there are much better pricing options out there Modulus arms has their raws for $29.99 and flat rate shipping of $9.00 and venom defense has raw billets for $30.00 with code 80bulider and free shipping.

I did a couple of the modulus arms billet blems and they came out fantastic with my 80Percent Arms easy jig 2 (but the 5D tactical and the modulus Arms jigs are pretty equivalent when it comes to finish work as well) Either way you can;t beat these prices with a stick. Probably the best you'll see for the quality.

My only other suggestion would be Tactical machining (when the blems are in stock that is.) they have a phenomenal lower as well at a good price point.

Tac machine right now are $29. No blem needed. Personally I think RTB gets them from Tac and their LPKs from unbranded.

Why the jacked up price? Its $44.95 at the website. I see no code for the $37.95 price. Just another 'good guy' using the mainstream media scare tactics to make extra money off the people.

Only way to build an ar 15. I have never bought a serial number,ffl ar15 lower. But I have built 5 of these with my 5d tatctial router jig. They give a great military discount and these are really good lowers to mill and turn into suppressed pistols. Stop buying serial number ar lowers. And be a real builder and build it from the ground up

Banned in NJ where I live. No longer allowed to "manufacture weapons" of any type. I would have liked to try making at least one.

Get your ffl license (class 7) and you should be able to after that. It’s 50 per year.

One of the improvements I would like to see fine to gun.deals is a better way of labeling a deal as expired. They were at that price when the deal was initially listed. I have bought plenty of items from RTB, and if these were back down to that price I would but several just to hold on to.

Why would you want an 80 lower already anodized? When you finish it, you expose bare metal making the anodizing basically useless.

Is any way to anodize them later ? Per what I saw only internals are becoming bare metal but all exterior look still look as a normal finished upper ? May be one can paint interior and get it done but how to paint exterior without making it look cheap?sorry for silly question, I built 2 rifles but never from 80% so looking for an advicd

Unless you are buddies with the right shop, you're probably not going to be able to get them anodized properly easily. You might be able to send it off, but most people leave the inside raw or go with cerakote. It's actually not that difficult and has a nice finish.

What’s the dimensions on the rear take down pin cut out?

That likely won’t happen again. Our machine shop was taking a loss selling them at that price trying to clear up excess forgings from the Obama era.

Hard to believe that when Primary Arms sells anodized 100% lowers for $30.

They've had these for $26. Whenever THAT comes back around I'll buy 4.

The threads usually taper off towards the end, they’re not “stripped”. It won’t affect anything because the buffer tube doesn’t screw in that far to make contact with those threads. If you have any issues, shoot us an email and we’ll get you taken care of.

Ordered 2 lowers a few months ago finally got everything set up and started milling one out last weekend and noticed the threads closest to the trigger pocket were what looked like stripped it's only the last few threads after the hole for the detent so hopefully it doesn't effect the buffer tube going on. And looking at both the lowers there were differences on how they were milled out before being shipped. One was more flared on the mag well then the other and in a few different spots one was more cut then the other.

Steel is what you want. It’s only slightly more expensive but will last MUCH longer

Yes, router type jigs are the way to go. 5D Tactical makes the best and most affordable in my opinion.

5D Tactical - Steel or aluminum ?

There’s hundreds of thousands of people with no prior machining skills finishing these. There’s a wide variety of jigs that make it easy for anyone with any skill set to complete these.

What is the best setup for completing one? Is it the router type method?

I have to agree. I have zero machine shop experience (retired cop here!) and after adding a compact milling table to my drill press, a drill press vice, a jig and milling bits, I've done quite well with several in-the-white 80% lowers. No need to buy the high end milling table if you aren't going to do production work. I grabbed a $30 one, plus a digital caliper ($10) to go with my very old mechanical one, soft vice jaws ($10) the jig & bit kit (went with sub.moa.com $175) cutting fluid (spray on $7) and used my thirty year old drill press. Safety is always a priority, so I did plenty of online research, chatted with real machinists, and have yet to break a bit, lose an eye, and my lowers are awesome.
The machinist I spoke with (my cousin) told me to cut very slow, remove limited amounts of material, back out frequently and check your work, and to leave a small amount of material for a hand fit rather than trying to play pro-machinist and perform a .00x" finishing pass. He also said to apply light lateral pressure because a drill press and a milling machine are designed for different tasks. Whatever, I believe the guy. Now I'm making plans for a 1911 80% frame, and other guns.

Great conversation piece, but unless you have machinists skills probably just a really cool ManCave paperweight or coffee table art

Conversation piece? Are you a creampuff or something? I managed to finish one with a power drill and vice because the harbor freight router I bought shit the bed immediately. And yes, the fire control pocket looks like I chewed it out with my teeth. But it is entirely functional in every way. Clean reset and everything. Coffee table art? You ARE a creampuff.

$39 at Tactical Machining ($49.60 shipped to IL for 1), $39.99 at Blitzkrieg Tactical ($48.99 shipped to IL for 1)

At Right To Bear it is $56.94 for one shipped to IL.

Just giving a few alternatives. Shop around for which is the best price shipped to you.
