What's the difference between the regular Mk3 lower and the "mil-spec" Mk3 lower?

What I'm guessing from that screenshot:

stripped: stripped
ambi: ambi lpk installed
mil-spec: more normal lpk installed

What do we think about the Meprolight HUD?

I'm hoping it's usable if you have eyeballs that are out of spec.

Anecdotal from one source (my friend) but Columbia River Arms was incredibly slow in getting a custom barrel done. If you're not in a rush then they're GTG.

Yeah, he bitched for months. Then turned around and recommended I buy one.

I think he just wanted me to suffer as much as he did.

It's probably worth buying the stripped lower/parts kit, which is what I'm planning on doing.

Even the assembled lowers are pricier than I want to spend without being able to choose exactly what trigger I want.

Yeah, I was a-feared it would be a $350 stripped lower. That's a pretty great deal considering you don't need a buffer tube, stock, or their associated hardware. If the LOP works for someone, it'd be a pretty great start to a decent AR, assuming there aren't manufacturing defects.

You will need two $4 pins and I bet money a special safety.

The last CavArms lower took regular safeties, so I'm not sure why this new version wouldn't.

The old GWACs Mk 2 stripped lower came with the special pins that it needed, and it used a standard safety. I assume that this one would be the same.

Oh then I'm probably wrong! Now I'm curious to know if these new lowers ship with the right pins since they're also sold seperately.

The old one also came with a special extra long buffer tube detent rollpin to retain the buffer detent because you cant use the buffer tube to do it. So 3 unique metal parts to it.

CAV lowers also like one longer hammer pin. Itís the same extended length as the ones that are used in the now fostech magnesium lower. You can get them from fostech and Vseven systems also sells extended hammer pins too. Itís not needed but it looks nicer IMO when the pin head is flush with the receiver.

I have spares of the long ones since Iíve been meaning to build up 4 CAVS. I can send you a set to try if a normal pin is shy of the surface.

The pins aren't captive, since those little detents and holes would create a weak spot in the polymer, so I think they're just planning on having replacement pins readily available.

On their Facebook page they posted a mysterious message about having to relocate and then have been awol for what, a year now? My guess is he sold off all his receivers and didn't want to buy a new set of tooling and punched out

Why even stay around if KE is doing one? How is KE permitted to even make them? Did they buy the patent? Licensing? Russel being on with KE really makes it seem that they just bought the patent or are licensing from GWACS and GWACS is going to retire.

How would...how does fairness testing dice work? I'm confused. If they aren't weighted what's the problem?

How precisley they were cast/ any bubbles in the material stuff like that. Maybe the 3 panel of your d20 is a 10th of a millimeter too high compared to the other panels. Maybe that gives it a tendency to roll more with the 3 panel being on bottom and making the corresponding reverse panel up more likely by .37%. It was NUTS man how offended people were getting

Yeah you can't use captive pins, the ones that came with my GWACS were just regular pins with a ball detent in the end. In addition the holes are offset juuuuuust a little bit so they are friction fit, since you can't have the regular detent snap them into place. It can be a pain to release the pins, actually, I usually use a punch.

Don't the pins sit a bit proud? You can usually use the edge of a hard surface like a table top corner or wood post to push the pin out just enough to expose and grab the flanged end.

Colt attempted to do this in the 1970s
https://sinistralrifleman.com/2019/12/10/colt-monolithic-polymer-lower-from-the-vietnam-era/

Cavalry Arms Corp released the CAV-15 in 2000, then the CAV-15 MKII in 2003.
https://sinistralrifleman.com/2019/11/22/the-mk3-polymer-receiver/
It was never patented or trade marked in anyway. With the Colt prior art it unlikely it would have been issued or held up.

In 2011 I sold the MKII tooling to GWACS after Cav Arms closed down. They ran it for a few years but had not produced receivers since 2013. The 2017 WWSD program caused them to sell out their remaining inventory.

We attempted to work with them to repair the tool and assist in running it and pay them a fee per part produced. The president declined. They were holding out for an investor. My point of contact left the company after having not been paid in a year. The president never responded to me, InRange, or Brownells, and people started complaining that their orders for spare parts were not being filled. In January of 2019 they posted the message about vacating their building and have not been heard from since.

KE Arms put together an investor group to fund development of new molds and tooling for the MK3. This program is something we have been working on for a while now. InRange created a demand, GWACS left a void, and there wonít ever be a better set of circumstances with the right combination of people involved to bring the monolithic receiver concept back.
