SOCOM M4A1 14.5'' Upper builds.

[WILDBILL]

Please post picture of your SOCOM upper builds? How many people have use CMMG SOCOM 14.5'' Barrels for their builds? How much does the 14.5''SOCOM Barrel weight more than a Reg. M4 14.5'' Barrel?

[Army Chief]

Not exactly a precise measurement, but I know the difference between the standard LE 6920 barrel and the SOCOM HB for the same weapon is about one pound -- keeping in mind that this is in a 16" (vice 14.5") application.

I have a CMMG M4A1 barrel. I need to snap some updated pictures, I have since added an EOTech 512, LaRue mount, Troy BUIS and Magpul enhanced trigger guard. I'll try to take more pictures tonight. The lower is an Anvil Arms (out of Lakeland, FL) They did the custom engraving at a Tampa gun show for me. It was pretty fun, I e-mailed Jon the Autobots logo and he gave it to his graphics guy who imported it to Correl and that is the end result.

If the profile difference is only under the handguards, the 1 pound difference should be the same regardless of 16" vs 14.5" OAL.

Here's mine. Colt 6920 lower w/ Colt SOCOM M4A1 barreled upper. I went with the permanently attached extended A2 flash hider by Sabre Defense.

Good point! I think I had it in the back of my head that I was referencing an overall weight figure too, but obviously I failed to make any mention of that. :)

Even so, the practical differences between a 14.5" and 16" (weight wise) just on account of the barrel -- assuming like profiles -- are likely pretty negligible.

I ran a CMMG M4A1 barrel with a KAC RAS for a while and liked the setup, I wish they still made that profile barrel because I want to do another build with a full length DD RIS II.

Franklin- BCM makes the M4A1 barrel if you want one.

The heavy barrel is a not very effective solution to a firing schedule issue(institution unamed...). Yes it takes a few more rds to heat up, but much longer to cool down.

A better way is to:
-increase surface area (flute, dimple, crinkle sandblast, or combo application)
-more effective venting through the handguards
-heatsink barrel nuts
-train on a realistic firing schedule that replicates the peaks & lulls of conflictThe above do help the rifle cool quicker but a heavier barrel still deals with heat better than a lighter one made of the same material. A lighter barrel my cool quicker but it reaches a higher temperature while dealing with the same amount of heat which leads to greater erosion.

Steel melts at the same temperature regardless of it's mass. Thinner steel needs less heat (fewer BTUs) before it reaches that temperature.

The argument that "lighter barrels cool faster" doesn't tell the whole story and is mis-leading

[Molon]

There is some seriously false information posted in this thread. The weight difference between a standard Colt M4/government profile barrel and the Colt SOCOM barrel is little more than 4 ounces. Here are some actual facts on the subject matter. All weights listed below are for the stripped barrel (the barrel and barrel extension only.)


Approximate stripped weights . . .

Colt 6520/6720, 16" light-weight barrel: 1 pound, 6 ounces.

Colt 14.5" M4/government profile barrel: 1 pound, 9 ounces.

Wow, didnt see last post was 2007 til now... I ended up buying a colt barrel, will be putting it on a 6920 with a DD RIS II and rattle canning everything.

Additional barrels added to post #14.

Don't buy CMMG barrels. Leave them for the Arfcom Inkjet printer repairmen!!!

That's going to be one heavy ass upper!

ETA - I ditched my M4A1 upper eons ago.

[ChromeLined]

I have the CMMG and im getting the BCM barreled SOCOM upper in a couple weeks.Weight increase is neglidgeable.I like a heavier barrel and this one fits the need and want.My rifles are real simple Aimpoint,BUIS and a light with standard handguards...removing the rails lightened it up and my needs for the accesories I use never required more rail space.If I want a foregrip I can always add a 2" rail to the bottom handguard.

[variablebinary]

Good thread. There has been lot of interest about the SOCOM barrel since the Army said they would be adding them to all M4's

I wouldn't want the extra weight personally on a semi weapon

[GermanSynergy]

Have you humped said platform in a carbine class?

I'm the guy that went from a Noveske Afghan to BCM Lightweight :D

Extra weight never used to bother me. But last class I took I was feeling every little ache and pain. :(

I wouldn't repeat the decision (as I have zero application for a SOCOM profile barrel), but my CMMG SOCOM 14.5" barrel really does shoot.

[xcibes]

Back from the dead YET AGAIN! :D

So, if a standard profile 16in Colt 6920 barrel weighs 1 lb 12 oz and the 14.5in SOCOM barrel weighs 1 lb 13 oz, what is the big deal with the weight gain?

I do not know about any of you out there but when I handled a 6920 with the 14.5in barrel and one with a 16in barrel, it made a world of difference ...to me at least.

If the information is correct, 1 oz should make very little difference and I would gladly trade 1oz extra weight if I can shave off 1.5in from the barrel. Of course, if I could find a standard profile barrel that would be even better. Anyway, what say you?

[jonconsiglio]

It should be more like a 4 ounce difference.

[xcibes]

It should be more like a 4 ounce difference.

No, I am talking about a 14.5in SOCOM barrel vs. a 16in 6920 barrel.

14.5in SOCOM barrel 1lb 13 oz
14.5in M4 barrel 1lb 9oz
16in 6920 barrel 1lb 12oz

The 4oz difference is between the two 14.5 in barrels (SOCOM and M4), the 6920 barrel is heavier than the 14.5 in Standard contour M4 barrel even though the contour is the same, simply because it is longer.

The top rifle has a Colt SOCOM barrel; the bottom has a cut down 6920 barrel to 14.5". I really like the SOCOM barrel. I personally don't feel a difference, and I carried a M-4 for work. Then again, my M-4 with standard 14.5" barrel was not as light as my old issued AUG or an MP-5.

Two weeks ago I had the opportunity to fire an H&K 416 with 10.4 inch barrel for a full day. That rifle is very front heavy even with the short barrel, so for those the complain about the SOCOM's weight should try carrying the H&K a full day

Well since it has been dug up again :D

Hi all. I am looking for help, volunteers, etc., who can write about the weapons of the war on terror, like the M4A1 Block 1 and Block 2.

A few friends and I formed a group called SOCOM Weapons Organization, a non-profit club dedicated to education and out of respect for the men and women who served in Afghanistan, Iraq and other places fighting enemies seen and unseen around the World to maintain our freedom and that of our allies.

I have a shell of a Website setup, http://socomweapons.org and am looking for someone to write a page about the Block 1, add some pics, then specs, and how to build a clone, etc. Then the same for the Block 2, then the Mk18, the Mk11, Mk12, Mk13, M110, SAM-R, SDM-R, 416, 417, M1A SOCOM, and so forth.

I have all the infrastructure taken care of. I might need help in the actual Website technical end on WordPress, but mostly content. Also, this should be thought of as not an encyclopedia of all the content, but will have links back to this forum, for example, and other sources where the primary information is contained. I envision socomweapons.org to be a starting place, with a modest amount of primary information (by lines encouraged, but not required), but with more links to all the available information contained elsewhere.

Please email me if you have the time, the passion and the knowledge to help.
