Colt Lightweight Sporter or 6920?

Light weight sporter has a pencil barrel, and among the millions of Colt models, it may come with fixed carrying handle or flattop.

Samething, one is lighter than the other.
 
Hmmm, tough call. Personally I'd grab the Sporter carbine but I like retros. Be aware the twist on a Sporter carbine should be 1:12 so it's best to stick to 55grn and lower.
 
The Sporter has the large pivot pin, and the 6920 has the smaller .25". It all depends on what you are going to do with it. If you want to keep it all original, or if you want to be able to swap out uppers. The Sporter also has different size trigger and hammer pins. If you want versatility and interchangeability with other common parts the 6920 would be the better choice, but if you want to go old school retro, the Sporter.
 
Have to admit the Sporter grabbed my eye because of the fixed carry handle. I can't lie, I don't know much about AR's. I like retro stuff, I'm not going to pretend I am knowledgeable about modern black rifles.

As it happens, I do have a few thousand rds of 55 gr fmj. Maybe the lightweight is what I should look at.
 
The thing about the 6920, is that it has a 1:7 twist, which will handle the light stuff (55gr) as well as the heavier stuff (63gr) the 1:12 will only or should I say prefers the 55.

Another option is to get the sporty and get another barrel. It only takes a few mins to do a barrel swap.

Partially correct. The Sporter does have the larger two piece pivot pin but the trigger pins are normal size. When Colt switched to the .250" pivot pin they enlarged the trigger pins. Both off spec sizes didn't appear simultaneously.

The two piece pivot pin is no big deal in my opinion. Biggest considerations are the fixed carry handle and twist rate. What do you plan on using it for?
 
Well then I say go for it. They're quite collectible as well. I'd love to add one to my collection but they're pretty hard to come by.

The 6920 on the other hand are easy to find.
 
What configuration is the Sporter Lightweight? I've been thinking SP1 carbine this whole time which is earlier.

Sporter Lightweights had A2 uppers I believe so the barrel could be 1:7 with enlarged trigger pins and normal size pivot pin. 16" lightweight barrels are my personal favorite. I consider them to be ideal for a nice lightweight fighting rifle.
 
Its a Sporter Lightweight, I believe its designated a R6530? The little I've been able to dig up is that it has a 1:7 barrel according to some specs online. One thing that attracts me is the price is just under 1000 bucks. That being said, its used and I haven't had it in my hands to inspect. No idea of its condition or mileage. But beyond looking at the bore I wouldn't know what I'm looking for anyway.
 
That's a pretty good price. 6530 had fixed stocks I believe? Easy to swap out though and you'd end up with 6520 clone which I would consider to be an ideal configuration. Ridiculously light (sub 6lb) and a red dot can be added with a gooseneck mount down the road if desired.

That's the info I've seen and this one has an adjustable stock installed on it. I kinda want it...might mull it over for a bit. I really need a lower for my retro commando clone but I get sidetracked easily.
 
Ugh! HBARs are pigs. They only exist because of the US CMP competitions.

I had an 11.5" HBAR that I replaced with a 14.5" M4. It's now three inches longer but weighs dramatically less.
