Is a Colt AR-15 M4 w/an LE serial number prefix; heavy barrel; bayonet lug; having no LE/government restrictions stamped on the right side of the magazine well considered an H-Bar? Thanks.
Thanks. The Colt in question has a heavy, possibly slightly tapered barrel w/ flash suppressor, bayonet lug, and without the grenade launcher cut.H-Bar refers to the barrel profile.
"The HBAR barrel profile is a thick-to-slightly-less-thick tapered design, thinning after the gas block. It was developed to add heat resistance and make the barrel more durable.
They’re big and heavy at the back, which helps mitigate heat up to the gas block, which has some benefits. If you live to mag dump, the HBAR makes a certain amount of sense, but the intended application is precision target shooters."
M-4 is also a specific barrel profile notably the notch forward of the sight for the M203 grenade launcher.
should be a 20" A2 configuration also.Thanks. The Colt in question has a heavy, possibly slightly tapered barrel w/ flash suppressor, bayonet lug, and without the grenade launcher cut.
I'll check the barrel length. Would one stamped M4 also be in an A2 configuration?should be a 20" A2 configuration also.
should be a 20" A2 configuration also.
My Colt with a 16” heavy barrel is marked HBAR on it.
This Colt is from a “Match Target” marked lower from the early AWB era. My 20” AR is also an HBAR.Honestly, I never knew there was anything but a 20" H-Bar... that 16" is interesting, besides the twist rate.
My 20" H-Bar is also marked on the barrel, but it is 1/7.

Stay safe.
Yes, its all carbine.As is my 20" (1992, I believe... just after they resumed production.) Fun fact: I strapped that rifle on the back of my Honda CB750 and rode home with it like that... back when you could do stuff like that.
Mine is a no fence, big pin, with SPORTER match hbar cal .223 rolled on the left... even though the barrel is marked 5.56mm.
Inquiring minds want to know... it's a 16" with a carbine-length gas system?
Well I was today years old when I found out too lol.Honestly, I never knew there was anything but a 20" H-Bar... that 16" is interesting, besides the twist rate.

Interesting that the barrel is marked 5.56, but the receiver is marked .223.Yes, its all carbine. View attachment 1203318
There is so much written on mine I just took a picture View attachment 1203319
Stay safe.
Same gun. Sold as a unit back when these were in the throes of being banned.Interesting that the barrel is marked 5.56, but the receiver is marked .223.
Or are those two different guns?
A Colt LE 6920 maybe? Just a guess.OK, here is the one I originally was inquiring about in my post. It has a 16" barrel, LE prefix, roll stamped 5.56 NATO with a P. What Colt model number is it? Thanks.

I guess the .223 caliber markings may have been an end-around so it wasn’t the evil war-machine AR-15 in 5.56x45NATO. The other stuff on there calling it a competition rifle sure was.
Is the barrel not marked “C MP”? I am suspicious that it doesn’t have a Colt barrel.
I was told by the original purchaser that it was a unit purchased new. TheThe lower receiver looks like the LE6920 I have sitting in my gun cabinet currently. The forge marking on the upper doesn't look like mine. I'm finding it a little odd that the barrel isn't timed for the markings to be on top; that looks like the bottom of an A2 flash-hider. Plus the barrel isn't mark C MP. Add the binary trigger and it's looking to me a bit like a Colt lower with a replacement upper. Looking again I see skinny handguards and not the fatter double-heat shield M4-handguards I'd expect. At least it looks like it's a civilian commercial lower built in the last 15 years with standard take-down pins and probably standard trigger and hammer pins (reference the binary trigger).
Then again, Colt loves to guns using whatever is available in the parts bin. Case in point: I had a stainless Colt Competition (Government Model) in .38 Super that had a blued trigger when all of the advertising copy showed the guns coming with silver triggers. And I believe the advertising copy for my blued Competition in .45 ACP showed a matching blued trigger, and my gun definitely has a silver trigger.
I was told by the original owner that it was purchased as a unit as it stands. However, I just had the Franklin Armory binary trigger unit installed & tested by my gunsmith. Where would I find the C MP roll stamp next to the 5.56 Nato? I also am curious as to what the "P" stands for, (proof mark maybe)?

I do not know the trustworthiness of the seller. I tend to take most people at their word, ( a short coming of mine sometimes). He is a friend of a friend. Maybe the pictures that I added in another post a few minutes ago will be of help. And yes, the binary trigger is a hoot and fun to occasionally use. I have them on two other AR's. One is a Springfield LAR 9 9mm, and one on a Bushmaster Patrolman Carbine. I have another unit that I am considering installing on a Savage MSR 5.56mm. I prefer the pull/release two shots over the rapid-fire MOST of the time. But............................you know how one can surrender to temptation sometimes. ;-)The “C MP” stamp, the barrel twist, and the caliber marking will all be on the same line, situated between the front sight and the flash hider. If the. “C MP” stamp isn’t there, I would not consider it to be a Colt barrel. The forge marking on the upper is unfamiliar to me too, although that’s less definitive than the barrel stamps. Personally I would not consider the whole upper to be a Colt factory unit (but I sure wouldn’t kick it out of bed). Is the person or FFL you bought it from very trustworthy? He also may have bought it from someone who represented it as all Colt, so one never knows in these situations. That binary trigger must be a hoot!
Edited to add: the “C” stands for Colt, the “M” indicates that it was magnafluxed, and the “P” is to denote that it was proofed, as you surmise.
