Seems like you could always make a set of press in bushing to convert a large pin receiver to use small pin triggers.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.
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 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.I was thinking about an Aimpoint patrol, How do you like em?

Never seen an “I” but this link shows other known markings.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
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.

I escaped the great Satan (Cuomo's NY) months ago.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?
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.Anyone have an idea of what barrel manufacturer stamps an "I" on the barrel? @Will555 @dsdmmat @Edwardteach72 , anyone?

Haha, yeah, the shipping is outrageous. Sick rifle though.@ArmedCorgi What about a Dutch AR10 with giggle switch? Armalite AR-10 308 Manufactured in the Netherlands "Dutch"
