Comparing the differences between newer and older Colt AR-15 lowers

[@jwehring88]

In regards to the triggers and safety selector, the "S" marking notates they were made by Schmid Tool. It is my understanding, on some of the parts in the newer production firearms, the Colt markings notate they were made specifically for Colt, to their specs since more parts are now being subcontracted after losing the military contract to FN.

[@thetexasgunvault]

Good information. Thank you for sharing!

[@chaoticcaninejb]

I wouldnt gp simply by markings. I know several big name manufacturers that have subcontractors, but the part's have to be made identical with markings. People would be suprised who makes what in this industry

[@thetexasgunvault]

You are correct.

[@hairydogstail]

Colt has always used sub subcontracted parts, in fact Colt has only made 18 of the 100 to 150 parts that go into their M-16/M-4/AR-15 rifles in their entire history. Colt's quality has remained the same and every part is inspected and checked in their lab to verify the parts meet TDP spec, other than semi auto parts which are never mil spec..

[@thetexasgunvault]

Glad to hear and thank you for the information.

[@travisbennett4091]

@hairydogstail wrong up until 2016-17 all colt rifles were 100% milspec in regards to dimensions. Metallurgy, and quality per the Technical Data Package, UP until 2016-17 Colt made all rifles to the exact same specs whether they were usgi m4s for the military or standard le6920 for the LE and civilian markets

[@hairydogstail]

@@travisbennett4091 No, I'm not wrong..Any semi automatic Colt or any other brand of AR is not a 100% TDP spec rifle..That said, Colt still uses TDP spec parts in their semi auto rifles, other than the full auto parts..This came from the horses mouth of the Colt rep Aron B..They still have their metallurgy laboratory that test their out sourced DOD approved contractor parts..

I purchased a Colt upper for my POF lower and found that the front take-down pin wasn’t working properly….. is there another manufacturer that makes a lower that mates up to that colt upper at the front take-down pin the way it should (without that adapter bushing, that is?)

[@thetexasgunvault]

I am sorry to hear yours it out of spec. I always try to keep the receivers the same brand. Like Colt/Colt

[@Critical-Defense]

Sounds like you tried to mate a Colt FORGED upper receiver with a POF BILLET lower receiver, that the case?

[@andrewsteele7663]

Good morning, Jason, I really do like the more "traditional' style of the AR platform. Cheers

[@thetexasgunvault]

I love the retro look.

[@marklosentes7988]

drop-in trigger(hipperfire PDI) is compatible for CR6920?

[@thetexasgunvault]

It should be. These are mil-spec so most will work.

[@Hoffsgarage3]

The notch on the hammer is designed to work with a BCG with an unshrouded firing pin. It catches the firing pin should the disconnector fail.

[@thetexasgunvault]

Great information. Thank you for sharing it.

[@zed332l]

The "CR" Designation on the serial number Denotes Colt Rifle..

[@thetexasgunvault]

Thank you for the information.

[@andrewpinheiro7202]

Colts been using cr prefix for a long time on le carbines

[@thetexasgunvault]

Yes, but I always had the LE markings.

[@andrewpinheiro7202]

@@thetexasgunvault the cr prefix Is the only reader I got my colt lowers in California lol the box said le but receiver said cr so I was able to convince the owner of shop that’s what It was so worked out good for me I personally like the roll marks better but unfortunately I got to be creative and take what I can get

[@DowntownDeuce2]

You totally missed the point and the significance of it. You are confusing model numbers with serial number/ production runs. There are no receivers dual marked "le" and "cr."

[@andrewpinheiro7202]

@ obviously you don’t know colt markings to what the model is I have cr prefix “serial number” guns that are in data base as “le “ it might sound crazy but very true and nothing new colt has been using cr prefix for quite a while even on older roll marked m4a1 socom with selector switch stops machined off .

[@DowntownDeuce2]

@@andrewpinheiro7202 Again, show me a single receiver marked with both le and cr prefix. CR began in 2018. They don't exist. You are a lumping commercial and defense products, based only on internal monikers, with production runs. I'm going to guess that you have no experience other than their civilian commercial products.

[@bigchomnk2934]

I have an older S&W mp15 from the 2010 timeframe and it seems to be of a higher quality to the newer sport 2s

[@thetexasgunvault]

I have heard that from others as well.

[@travisbennett4091]

Trigger group isn't Colt, colt triggers have a notch cut into the trigger itself by Schmitt tooling,

[@thetexasgunvault]

It is my understanding they sourced from other places for awhile to keep up with demand.

[@Critical-Defense]

Doesn’t matter, trigger is coming out no matter who made it unless it happens to be Geissele.

[@andrewpinheiro7202]

The one positive thing on new colt lower is at least they have selector stops

[@thetexasgunvault]

I do agree about that.

[@dingoduh]

This video tells me I should avoid the new Colt ARs, because QC is compromised for profits.

[@thetexasgunvault]

Some people say that's the case.

[@shanewhitted1]

Colt is the same quality as always. Different markings are just that. They outsource parts are tested to meet the requirements and TDP. Actually BCM AND Colt use Microbest BCGs and are tested exactly the same way. They are the same parts, different markings. Colt and FN both have used outsourced parts for a very long time. Markings or not. They are not cutting corners. CR….. Stands for COLT Rifle…CR makes a lot of sense right? 🤷‍♂️

[@thetexasgunvault]

I guess so. Thanks!

[@shanewhitted1]

@@thetexasgunvaultno problem. It’s just something I learned while watching these videos. A lot of misinformation about Colt? They have always outsourced 🤷‍♂️ I see people saying “Buy BCM, they are superior to Colt in every way possible now.”😂 the laugh is because I found out that BCM uses the EXACT same parts. Microbest. They are both tested to the exact same standards. Only difference is markings 🤷‍♂️😂 I know we can only say what we know. I don’t bash companies without knowing things like this. Because those commenters look like fools when an expert shows up to put the truth up. BTW, I am NOT an expert. I love my Colt LE6920 FDE Magpul SL edition. 2018 version. Has the old LE roll marks but a CR serial number prefix. And cage code instead of C. I saw it being bashed and someone saying it wasn’t a Colt and lesser quality because they changed the markings?🤷‍♂️ I investigated to make sure. He was wrong. It’s just markings and your Colt is still the same quality and is still a Colt. I understand that collectors want certain things. But I just wanted a Colt rifle and got a Colt rifle. Now I get picky on my AK collecting so I understand that. Love those 2 Colts you have!!! Enjoy them man!!!😎✌🏼

[@Critical-Defense]

@shanewhitted1 - Great to see someone who gets it in a sea of grandstanding complainers. @thetexasgunvault - Great to find a channel with love for Colt too

[@Lester.M]

Carbine mark is cringy.

[@thetexasgunvault]

I completely agree.

[@davidschaadt3460]

Especially on a rifle.

[@davidschaadt3460]

Loads of complaints about that.
