I have a Colt AR15 HBar Sporter that does not have bayonet lug. I want a piece in my collection to represent the C7, so I was wondering if it would be a big deal to change the front sight assembly on this rifle to one with the lug? Has anyone out there ever tried this? Does anyone out there have a front site assembly with a bayonet lug they want to get rid of? Thanks.
Bayonet lug for AR15

The front sights are easy to change. The pins which hold them on can be drifted out (left to right).
However, I do not know if a bayonet can be mounted on "any" barrel... the length and diameter have to be right (and I don't know what those are).
Maybe someone will post that info. Good luck!

If you're concerned with being faithful to the C7 insofar as you want to have a bayonet lug, then perhaps another rifle altogether would be closer. You'll need A1 sights and a 1:7 government profile barrel at the least. You might even need an A2 receiver, as some of these rifles had A1 receivers.
As was mentioned, getting a new front sight base for a colt will be quite difficult. Also, swapping barrels may be more trouble than it's worth. The easiest solution, given the A2 sights on that rifle, would be to get a brand new complete upper that is closer to the C7 specs.
Not to say you shouldn't try to find the correct FSB; that would certainly be cheaper. Good luck.

Swapping barrels is easy, and as sparrow pointed out, the front sight is not interchangable with any new/different sight.
Sooooo they easiest/best thing to do, if you are happy with the way the upper and lower receiver match in colour, is to find another barrel. It's a 4.5 minute job.

For some reason, the Government profiled A2 barrels are kinda rare and harder to find on the EE Forums. Hvy barrels are all around us for around $ 300 forward of the upper reciever.
Like you, I kinda like the C7A1 rifle look for Service Rifle competition and once we slap on the green round handguards, nobody will ever notice the "skinny-fat" or the "fat-fat" barrel contour.
So is having a "skinny-fat" barrel contour worth all that trouble finding one ? Personally, I would just buy one of the many HBAR 20" barrels that often come up for sale in the EE Forum. It seems to me that the modern trend is to change your 20" barrel into a 14.5" or 16" carbine tube.
Hope this helps,

If you are shooting both M193 (55-grain) and M855 (62-grain) Ball, I suggest that you get a 1 in 9 twist barrel. The 1 in 9 will shoot either without any accuracy problems that happen with the 1 in 7 twist.
Bushmaster Firearms makes very good M16A2 Mil-Spec 20-inch 1 in 9 twist barrels w/bayonet lugs. I'd suggest you replace your Colt with one of them. It is a very easy and straight forward job.

It is true that the chance of the pins lining up with a new FSB are slim to none, however that doesn't mean that it can't be done. I have an Armalite upper that came with their cheesy clamp on FSB that I just couldn't stand, so I bought a used Colt FSB and took it Epps. The barrel had already been drilled for pins, did they line up properly? I don't know. All I know is that when I got it back I had a solidly mounted Colt FSB. I know at least one other member on this board (who works in a gun shop) did the exact same thing.
Your other option, besides replacing the entire barrel, is to find a solder on bayonet lug. I know they exist, just can't remember who makes them. I wouldn't be using a bayonet on it but if you're just going for looks, it would probably be the cheapest/easiest route. Kurts Kustom Firearms is sticking out in my mind for some reason.

Or... you can go by way of "oversized" taper pins. You'd have to find a new FSB that is drilled in "close" to the same location that your barrel is before proceeding though...
