I am also surprised. Maybe not many know about this source. I wasn't familiar with them until it was posted here. What sealed the deal for me is that the lowers have safe/semi vs safe/fire.

I think inflation is really catching up with people. Most of Colts current offerings are available in stock and even under MSRP.

Ammo is still 0.50+ a round, traffic at my range is way down lately.

I’m trying to hold out on the release of the M5, but would really like the double bullet marked lower.

I didn't really need to spend the cash to get one right now, but I have been looking for a M4LE lower and they seem to sell for crazy prices. 17 months ago, I bought a 6933 SBR with a M4LE lower to satisfy the itch for one and it's still in ATF jail waiting for my form 4 to be approved.

When these came up for sale, I decided to go for it until my other one gets out of jail plus these lowers do have the safe/semi selector marks.

The way I understand it, they only offered M4LE lowers on the 6921 and 6933 SBR's and the only way to get one is either buy an SBR or find a lower somebody notified the ATF that it was no longer an SBR.  

Anybody have a clue as to how many years the M4LE rollmark was used?

More importantly, are these large pin or small pin FCG?  Semi or FA Bolt carrier?  How is the general condition from those here who ordered one?

I’ve read internet forum posts that state Colt transitioned from .169 to .154 FCG pins after serial number LE050000 or LE060000.  I haven’t come across any definitive documentation from Colt.  I have a handful of M4LE lower receivers.  My LE045XXX M4LE receiver has the larger pins.  My LE097XXX M4LE receiver has the standard sized pins.

I purchased a rifle with a LE097XXX M4LE lower receiver in 2010.  The M4LE lower receiver in the link has a LE007527 serial number.  I believe that’s a 1998 or 1999 production serial number.

It looks like a mixed bag of items. Mine will hopefully be here 8/22 so I will know more. They did sell some on GB and one had a upper marked with a C and AF, the other one had a keyhole and Diemaco marking. It also looked like the bolt had MPD on it.

Item #942183471 and 942151788.

I called them, they said they should all have semi auto carriers.  As another poster said, the SN puts these rifles around the late 90s so that would be common production for then on semi guns, as well as large pin FCG.

I picked mine up today, SN# is LE0076XX. It has a C marked upper with AF forge mark. Bolt is marked with MPC and carrier with a C. Carrier is a half-moon unshrouded semi auto carrier and the lower has a large hammer pin. Barrel has MP and C with the side sling mount. I called Colt and they told me build date was 2002 and it the left factory as LE6921. Lower does have the safe/semi markings.

Overall condition is pretty good and the rail looks new, but it did not come with any rail covers.

Sorry sounded bad/badly worded, I love the roll mark it’s just some “forge markings”? next to the LE roll mark and some of the roll mark has different depths haven’t seen anyone else’s look like mine it’s just a rough roll mark compared to others

I buy rifles to shoot, special markings may look cool, but they don't help the rifle shoot any better.  Unless the price is VERY attractive, I won't pay any premium for markings that don't help the rifle shoot any better.

Many police trade in weapons are used for annual training, sitting in patrol cars, or armories, but not shot all that much so they can be priced well.  But if it was $900 for a used trade in and $900 for a new rifle both of which were made by Colt, I would buy new.

Coloring of selector markings does not get done at the factory. Anytime that you see that, it has been done by the user at some point.

The coloring is often done with crayon compaction or enamel hobby paint. If it doesn't come out using a qtip and some rubbing alcohol, I would get a small bottle of hobby enamel paint thinner from places like Hobby Lobby or Michaels craft stores and try that.

If you do use paint thinner, rub easy and follow-up with a good oil rub down of the exposed areas. Paint thinners often rapidly dry out the surface.

Having said that, it is only a guess as to what the previous owners actually did.

Thanks.

First of all, love your site. I just got my first ARs, both pd trade ins, within the past cpl of months. Other than the retailer telling us which pd department they came from, any clues/hints that you can share to definitively track down the pd dept? Colt archives will probably only show the distributor.

I have 5 colts now and they are all pd trade ins. I know the dept origins of 3 of them
