Can anyone tell me about the Colt M4 socom barrel? If anyone here has one can you tell me what you like about it? I picked up one slightly used for a good price. I know they are very heavy under the handguards but what about accuracy and such. Being as heavy as they are I assume that using a heavier stock like a sopmod would help it balance better.

thanks,

Jim

They shouldn't be any more or less accurate than the standard M4 barrels. The extra material is good for longer periods of sustained fire. It will be heavier, and a heavier stock will help to balance it out.

Ive always loved HBARs for the heft and taking the heat way better.With a SOCOM barrel I got the best of both..still takes the heat but is lighter than HBAR and a little heavier than standard.

The weapon will be front heavy, you have to deal with it, especially with you doo dads. You will have comfort of knowing that you gas tube will fail before the barrel fails. The LMT SOPMOD stock is the master. To be honest I believe my A4 handles better but the M4 SOCOM is tiny. It is easier to keep on target due to the weight and our friend inertia.
Here is mine. A factory complete Colt SOCOM upper with added PRI Gas Buster and KAC M4 RAS. The lower is a old prebie Bushmaster with LMT LPK and LMT stock.

thanks for the replies guys.... I have a spare LMT stripped upper that I picked up on the EE that I will probably mate it to. Along with a LMT lower with SOPMOD and throw in a BCM bcg. Just have to figure out whether to put on a rail or go with regular handguards. Optic will be a T-1 in a Larue mount.

Mine balances great, just like this. Not front heavy in the least.



Here it was last week:

I'm running a 6921LE Colt with SOCOM tube, and it rocks the house! I've got a MIAD with bolt and pin, a Vltor modstock slider with SOG rubber
pad, a steel charging handle, plus the Modstock has some extra goodies in it.....throw in a carry handle and you can see why my M4 is actually
a little stern heavy.

Some dude used to sell these on the site a few years back. I'd just wait to see if the Mil switches back to them.

They'll be hitting dealers shelves by the ton, I'd guess.

They're around, and pop up for sale. Expect to pay anywhere from $350 to $500, used and new. You'll get tons of hits on Google, but most are usually links to expired sales/auctions.

When someone is selling one, it's not for sale for very long.

I've got two, one on a Colt 6921 and another I just picked up a few weeks back for $285 on EE. It will be waiting at home for me to put it on top a 6520 lower I have and A2 upper.

Not me, mang. I don't have a giggle switch so I like mine to be as light as possible.

I had one from CMMG, too. Then I realized I was retarded, so I don't have it anymore.

Here is my non-NFA and all Colt SOPMOD clone with M4A1 barrel. It is definitely heavier than a govt profiled M4 however I would not say it feels front heavy.

IIRC, it's about 4-5 oz. heavier than the same tube in Gov't profile. Along with the Colt, I also have one in CMMG. You CAN feel the difference
in weight, but it's not that great. Certainly nothing like that artillery tube you find on the Colt 6721LE.....Colt's Tactical Cannon !

LOL...I agree. My 6721 Colt finally felt balanced when I removed the FSB, HG's & delta ring assembly and replaced with lo-pro gas block & 9" D.D. rail.

FWIW, the ArmaLite Middie, of which I am the proud owner, has a barrel profile almost exactly like the SOCOM tube. This is one of the most
spectacular EBRs I've ever owned. Handles like a dream, with either an A2 stock or telestock....it came with both.

This works for me. From now on all Carbines in the harem will be SOCOM weight or better. I will leave my Bushie M4 with it's Gov't bbl. as a
reminder of "how it all started" Wonder if this will have a trickle down effect on what Colt uses on the LE weapons? Can you envision a Colt
M4 or 6920 type piece with a factory SOCOM and permed Phantom/ 14.5 combo? I'll take a consecutively numbered pair !

6920s with heavy barrels have been done before, and they are completely pointless.

Nope... have had the barrel sitting in the parts box for near six months now.... been going back and forth whether I want another M4gery or not. I already have a complete LMT. A nagging little voice in the back of my head keeps whispering recce... recce... but I have been ignoring it so far. Now that the holidays are through I need to get going on it. Probably going to go ahead and put it together, slap some krylon on it and shoot it. Save the recce for later in the year. we'll see.......

I guess that makes the 6721LE pointless too ! Anyway I'll take the 14.5 SOCOM 6920/6921 M4....not the 16", at least not right away !

SAW did them LE6921HB 14.5" SOCOM barrels... i feel like i am in a time machine... username Skich was selling those SOCOM barrels on the EE like 5 years ago...

i have two... aside from the fact that i already own them and they have the newly found "cool" factor... they don't do much in semiauto that a standard M4 profile barrel or even better a lightweight can't do...

Yup, there was also a 6920HB run.

Anything more than standard profile (that's "lightweight" or "pencil" to some around here) is pretty much useless for civilian shooters that don't have a giggle switch, and even then the 100s of thousands of Model 601, 602, 603, 604 etc. M16s did just fine in Vietnam with standard profile barrels.

What's the point? So you can make your M4 into a SAW?

Fire discipline, that's what caused those failures. No point to this at all, unless you are specifically building an M4A1 clone.

I agree completely with Joe.

I had two and put several thousand rounds through one. Good barrel, but after it shot out I tried a standard colt 14.5 and was much happier with how well the gun balanced, I sold the other barrel and am using gov profile exclusively now. The extra weight will definitely make your gun front heavy unless you have a heavy stock like a UBR or SOPMOD. I think people wanting them is just a knee-jerk to the fact that the military switching to them. If you aren't shooting auto, the extra weight is a liability.

Meh. I like mine. NOT front heavy. at least for me.

Exrta weight is 7 ounces more than standard.I am amazed at how people point to weight when with everything they put on their carbines it turns them into an M14 weighted carbine.Bottom line heavier barrels take the heat better and even though I dont shoot full auto I like my rifle to be the best it can be.That being said I have lighter profiles as well.Without full auto RPM for an AR is only 15 rds per minute..with a heavier barrel that increases to 20-25 rounds per minute.

As we know DI operation and especially carbines run real hot so I would rather have a barrel that can take more.Next well here about how piston systems are not needed yet the heavier barrel and piston drop in are reqirements for interim upgrades on the M4 whn it gets revamped by 2013.As far as fire discipline I agree that causes failures but what choice do you have but to use the carbine as a bullet hose to stop your posistion from being over run...some times large volumes of fire is necesary and lighter barrels cant take that.Am I fighting off human wave attacks...no but its good to know my rifle will take it.I have always loved HBARs for the obvious benefits but now theres a barrel that provides that at less weight.

I would get one of thses but the price is way to high for just a barrel when I only own a semi auto colt. Dont get me wrong I would love to own one, but paying 300 to 400 bucks for a barrel i dunno.

I was talking to a guy the other day who said the REAL reason they went to a heavier barrel was that people were getting their M4s slammed in humvee doors (heavy armor-plated) and this was putting a slight bend/kink in the barrel causing it not to shoot straight. Not sure I buy into that, but...
drw1006  [Member]

The reason for the thicker barrel was that SOCOM wanted their M4's auto not burst. The longer rates of fire (heat) was warping the barrel so Colt beefed it up.

M4 = Safe/semi/burst with standard barrel
M4A1 = Safe/semi/auto with heavy barrel.

I agree 3 or $400 is a big chunk of change for a barrel.It took me a little time to save up for it but it was worth it.I paid $350 for a CMMG socom 2 years ago and then a more expensive Colt a year later for my main and back up carbines..of course last December and last January they got upgraded to Osprey 416 drop in pistons..hey just trying to stay ahead of the new requirementsboth run great and are real accurate...of course I shoot 100 yds and under where 95% of real life engagements take palce..if I go farther I go M14.The barrels are great although Im partial to the Colt barrel.I went back to standard handguards for the Osprey system but have an attachment for my foregrip and I use an Aimpoint/BUIS combo and a light thats about as accesorized as I get.

I could have gotten the MI rail that fits but after I evaluated my rig its really not needed and lightens it up a bit.With no railed forend its the same weight now as it was when I was using the rail with a standard profile barrel so nothings really changed weight wise..performance wise I have a real accurate way cooler running rifle that hasnt needed lube in the last 1500 rounds..the slip2000 grease "grease just works so much better for pistopn operation"the same lube is still on the carrier from 21/2 months ago..I love having my AR work like an M14 without M14 weightI wish I could buy new production 6920s then all I would have to do is change the grip,stock,trigger guard and drop in an Ospery instead of having to rebuild pre-bans to that standard.But my state sucks..not as bad as Kali but still sucks

greta point,

but if someone needs all that stuff more then a SOCOM barrel thats where trouble starts, I would rather have extra weight from a surefire light and DBAL then I would a SOCOM barrel carbine with nothing on it. The standard profile makes the gun mre efficient for use with mission essential extras. If SHTF do would you feel better with a stock heavy carbine because of a SOCOM barrel, ( which you cant carry enough ammo to melt it anyway) or a haeavy M4 with a light a rail and optics that make it mre effective?

I do like the SOCOM but it will not matter in semi. ever. it would take some real serious effort to overheat a standard barrel in semi and the HBAR accuracy is debatable.

If you can do without the M4 'notches', a CMMG Medium-Contour barrel has the same benefits as the SOCOM.
ChromeLined  [Member]
3/8/2010 7:13:28 PM
In my experience the only real accesories needed would be a light,foregrip and a red dot or Acog..either way you can attach all that stuff without using a rail and have just as effective fighting firearm.But im also from the train of thought is even with all the technology out there I could get by with an Aimpoint and my iron sights and plenty of ammo.Or just my irons..hell you would think that we were never able to kill the enemies of this country with just a rifle,ammo and a good set of bootsas far as Im concerned thats all you need for Combat..oh and dont forget the water.
