Wasted no time getting the m4 handguards swapped out. I put my Aim point on it and replaced the magpul bus with my MI rear flip up. The build seems to be very solid. Upper and lower were meant for each other, no slop and yet very easy to take down, as it should be. Cage code and M4 stamped on the upper with a square forging mark. Barrel has the cage code on it and under the handguards it's stamped "I". Not sure which subcontractor that means, but I know Colt hasn't made barrels for a while. It could also be a blank that Colt finished. Hammer has the notch with the ss markings. Bolt carrier has a faint dot matrix C and bolt is also faintly marked MPC with an A. I know there is a lot of speculation amungst the purists about just how much of this rifle is actually Colt. I'm not sure I really care. They lost their government contract which means they are not required to mark components the same way they used to. So more things may be subbed out but it's also possible that things are mostly the same as earlier gen Colts, they just don't have to mark components the same way now. I know the whole Colt TDP was the main reason people wanted Colt, but this appears to be a solid, well build rifle. I'd imagine for their 6920 line, they would at the least use parts that were their spec, even if subbed out.

Do the newer Colt AR models have a different larger, trigger pins that make them incompatible with current AR trigger sets on the market today? I've always heard of the large / small pin issue on Colts that made then incompatible with current trigger groups.
Edit: Found the answer online.
If your AR-15 rifle is NOT a Colt you don’t have to worry about “Large Pin” triggers as an option for you. Large Pin AR-15 triggers really only apply to Colt rifles as Colt is the only AR brand to have ever produced both small and large diameter pins in their triggers. Generally speaking Colt AR-15 rifles produced before 1991 and after late 2009 accept small pin triggers while rifles produced by Colt between 1991 and late 2009 commonly take large pin triggers.
Since Velocity Triggers produces a couple “large pin” triggers for older model Colt AR rifles, you’ll need to take a measurement of your hammer and trigger pins if you’re purchasing our large pin trigger for a Colt rifle. Small pin diameter are generally 0.154 in. in diameter while our large pin triggers are designed to fit AR-15 lowers with a pin diameter of 0.174.

Seems like you could always make a set of press in bushing to convert a large pin receiver to use small pin triggers.
It might require drilling the pin hole even larger to make room for the bushing, and you might not want to do that for reasons unrelated to the functioning of the rifle, but you could if you wanted to.

I was thinking about an Aimpoint patrol, How do you like em?
2nd was Eotech and third was Trijicon MRO . Ive never used a red dot But everyone seems to like em .

I'd say a T2 over an MRO if you can swing it (or even H2)

I dont think I like the T2 because the window seems so small. I like the window on the Eotech but it seems like brick .I dont know, without haveing used them myself , I cant really say.

I have the Aimpoint m2 comp. So far I like it. I'm used to that style red dot. The only issue and it may not even be one for you, is if you have astigmatism the dot will tend to be fuzzy.

Anyone have an idea of what barrel manufacturer stamps an "I" on the barrel? @Will555 @dsdmmat @Edwardteach72 , anyone? I'm researching it but have so far come up with no answers. I know "R" is Rosco and "G" is Greenmountain but I don't know what "I" means
Never seen an “I” but this link shows other known markings.

That was one of the pages I came across. No mention of "I" markings there. The barrel on my Colt has the same "I" marking as in MAC's video posted earlier in this thread. He just said it's the identifier for the subcontractor and didn't say who. It's not really a big deal, I'm just curious to know who made the barrel/barrel blank.Never seen an “I” but this link shows other known markings.

Overall I am really liking this rifle. The only flaws I have found so far are some machining/milling marks on the inside bottom of the lower (which no one will see unless they open the rifle and look). I researched this and found a thread on ar15.com about colt machining defects and some of them are pretty bad. Like "how did this pass inspection" bad and on lowers from the LE6920 days, before the QR codes and engraving. So I don't feel bad about it at all. In fact, it makes me think the lower is definitely Colt made, lol.
My dad still has the Colt Sporter I bought him in 1993 NIB. Doubt he will ever shoot it or sell it.

So reading through the comments on MAC's video, it was stated that the "I" marking was the company that did the chrome lining and not the bbl maker...Said "Frens03 6 months ago
@B 1 the I is either the chrome lining contractor or the barrel BLANK supplier. All colt barrels have an extra marking near the chamber even my 1971 m16a1 has an “O”.. please stop spreading bs.."

Nice Colt AR. Just curious, how did a NY FFL accept this rifle and transferred it with all the "bad" features and a detachable (30-round) mag? The 2 FFL's I use would have sent it back as soon as they opened the box. Have the NY UnSafe Act laws changed and I 've been asleep?

I escaped the great Satan (Cuomo's NY) months ago.
Yeah, sorry. I can’t think of anything specifically with an “I” stamping. But it seems like you might have figured it out with the whole sub contractor for either the chrome lining or the barrel blank.

@ArmedCorgi What about a Dutch AR10 with giggle switch? Armalite AR-10 308 Manufactured in the Netherlands "Dutch"

Haha, yeah, the shipping is outrageous. Sick rifle though.
How much do they go for
