This may be redundant but I've done quite a few AR15's with the Tactical Machine lowers and always liked their product. Also have done several .308's on the Genesis receiver sets. I chose them because I'm hoping my Armalite uppers will work. I;ve also built a few compleete rifles and the fit and finish between their upper and lower is really nice. Their dimensions don't seem to match any drawings I can find but I use their tooling to get a starting point. I machine the fire control pocket form drawings, not from the tooling they sell. The Tactical Machine jig and tooling was really nice...the Genesis stuff took a little work.

Recently purchased and received a few 80% lowers from Thunder Tactical aka Discount Parts & More. I was skeptical but they were nice on the phone and I can confirm the rear pocket is milled and the receiver is marked safe/fire. Anodizing looks good and uniform but I haven't measured anything or milled it out yet. I used code laborday10 to get 10% off. Address and phone number are different than Daytona Tactical if anyone is curious.

EP Armory has aluminum and plastic lowers. Their plastic blems are probably a good way to practice and get your technique down before you start cutting aluminum. In bulk, they get down to $12 something per lower. They also have a Glock mag aluminum 80%.
I've heard the Andersons do not have the LRBHO boss roll pin hole drilled. |

Hi folks, does anyone sell an 80% forged lower that matches the style of the early FN M16A2 in this post by MauserMatt? The particular detail I’m looking at is the lack of the cylindrical “bulge” / reinforcement on the right side at the rear of the receiver were the hole is drilled from the back end for the takedown pin detent / spring. I’m still looking through the links in the OP, but so far, all of them show that reinforcement that characterizes a later lower. I’m guessing I may have to look at having someone mill off that detail for me. Thanks for any help you can offer!

For 80% Arms lower, you have No for rear lug. All the ones I see they offer does have the rear takedown lug already cut out.

I ordered a Cerro lower from RightToBear two weeks ago and was disappointed to discover that the design of the lower they are selling has changed. Their product listing states, "These RTB 80% Lowers now come with a tension screw hole drilled and threaded for a 1/4"x28 set screw (set screw sold separately)," but more has changed than that. The shape of the "collar" at the rear where the RE screws in is fatter and more rounded, the magwell fence has a sharper point at the bottom, and the raised area on the left side of the magwell (where the channel to clear the bump on the magazine is located) is narrower. None of this affects the function of the lower, but the appeal of these Cerro lowers, for me at least, was the ability to clone a military-issued lower, and these new lowers are no longer a visual match for the military version. Here are some comparison photos:
Old Cerro lower (Cerro keyhole was machined off when engraved): ![]() New lower (website states, "Cerro Forge (Key hole may or may not be machined off)" but I can't find any evidence that this lower had a keyhole): ![]() Comparison of rear of lower (old on left, new on right): ![]() Magwell comparison (new on top, old on bottom): ![]() New tension screw hole (I didn't want this feature but could have lived with it since it wouldn't be seen): ![]() RTB was very responsive and sent me a label to return the new lower, but I'm bummed that I won't be able to go to them for a clone lower anymore. They offer great service. |
|

So it's an M-16A2 lower forging instead of an M4 lower forging?

No, that’s what I thought at first, but the rear part of the lower doesn’t match the M16A2 design. You can see in this old post that the A2 “collar” tapers down to a horizontal line, not an angled one like this new lower. There seem to be some variations in that, but none like this new RTB lower. The A2 looks more like the M4 lower without the raised cyndrical bump for the take down pin spring / detent. I spent a lot of time staring at photos because I was going to see if I could have the older style Cerro lower modified to clone an A2 lower. All the M16A2 lowers I looked at also have the standard width vertical “channel” on the left side of the magwell. I don’t think the point on the A2 magwell fence is quite as sharp as this new lower’s either.

I just ordered 2 skeletonized lowers from Thunder Tactical:
https://thundertactical.com/product/80-lower-skeleton-raw/ I also hope to get a couple of lowers from Iconic Industries. They've got some pretty good looking lowers: https://www.iconicindustriesinc.com/15-style- I think I'll grab a stealth & an instigator. I'll update when I've gotten to machining them. On a side note, I was in a local gun shop today, and the guy was selling Anderson AR-15 stripped lowers for $75 each... The last time I bought an Anderson lower, I spent $30. |

I continue to run into challenges in my effort to find another source for Cerro 80% lowers like the ones the RTB used to sell, in my first photo that I posted above. I ordered one from JSE Surplus but really didn’t care for the way theirs were finished. The front face and lip of the magwell were ground down pretty drastically - it didn’t look like any military magwell that I’ve ever seen, which made it useless to me for cloning. I know I’m a bit picky, but after buying a couple of the good-looking Cerro lowers from RTB, which are no longer available, the Cerro lowers from other sources just aren’t the same. JSE checked their inventory for me and said that all of theirs are finished that way. They understood what I was concerned about and accepted the lower back for a refund.
The JSE Cerro lower is on the left, and the old style Cerro lower from RTB is on the right: ![]() Edit: I forgot to mention that the JSE lower also has a much smaller funnel / bevel milled around the inside of the magwell than the old RTB Cerro lowers have (along with most other factory lowers I’ve seen). A good example of the importance of who is finishing the lower vs. who made the original forging. RTB Cerro on top and JSE on the bottom: ![]() |

I’ve been thwarted again in my search for a “normal,” standard, MILSPEC-style 80% lower. I ordered a Anchor Harvey 80% Lower Receiver from Gorilla Machining and received it today. It’s described on their website as a “Anchor Harvey Raw 80 Percent Lower with Optional Safety Engraving,” which I took to mean that you had the option of selecting whether you wanted safety selector markings engraved on the lower, like Right to Bear offers. I couldn’t see any place to select the markings, but I figured you were supposed to write them in the order comments or something. Since I didn’t want any markings, I just ignored that, which maybe I should have looked into more closely, but “Optional” was the word that stood out to me. Sure enough, the lower showed up with “SAFE” and “FIRE” engraved on it, which was not what I wanted, since I’m planning to have it custom engraved:
![]() However, when I turned it over, I discovered that it had a strange groove engraved in the left side of the receiver extension “collar.” I’ve never seen this on a lower before and have no idea what the purpose of it would be. It almost looks like it’s designed to provide clearance for the rods on a PDW stock or something, but since there’s no comparable groove on the other side, it would only have clearance on one side: ![]() ![]() The product image on their page is apparently just another generic photo, since it doesn’t show the selector markings or the groove cut in the side. It looks like I’m going to be returning another order, although I’m sending them a note to ask if they have any of these lowers without the markings or milled groove. It’s unfortunate, because this was the exact style of forging that I was looking for. It appears to match the ones used by LMT, BCM, some older Colts, and a few other brands, which are different from Cerro’s forging. |

Maybe the groove to help you install the bolt catch pin which is why it's only on one side.

Aha, that’s a great observation, thanks! I never would have thought of that, since it would require a really long punch. I have a set of long Grace roll pin punches that won’t even reach that far without the handle hitting that area of the receiver. I’ve always used one of those specialized half-cutaway punches to install that roll pin, so I never thought of that.
Gorilla sent me a return shipping label, so it will go back to them tomorrow. They said all of their Anchor Harvey 80% lowers are like that. |
