I'll just put this right here... was 11 degrees F today, but I still made it out since I had the day off....  Got the Ecos zeroed and dialed in at 100m.  I may have to loose the matech and move it further back though...

Just when I thought I was ready to build. Now that I know 99% are m4 profile, can't use a socom because reasons. Anybody have a new C marked M4 barrel they would like to get rid of?

The factory slotted screws are garbage.  I had some leftover allen screws that fit and I rarely carry a flathead screwdriver with me.  Back to the barrel conversation.  I like my SOCOM barrels.  They are accurate and easy to acquire.  The weight savings with the M4 barrel over the SOCOM is negligible to me.  My rifle is already a fat ass pig, so it's not a concern for me.

What's the deal with Socom barrels?  I thought they were the go to barrel now everyone is saying they aren't!

Which is it then!?

All new M4A1s since a while ago have heavy barrels. However, Crane Upper Receiver Groups are built with the not heavy standard M4/M4A1 barrels (including 10.3" and 14.5").

So if you are SOF and have a newer M4A1 that has had a RAS, RIS II, MK8, etc. added by a unit armorer, it probably has a heavy barrel. If you have an M4A1 Lower Receiver Group with a Crane Upper Receiver Group added to it, it has a standard barrel

Hey, I've been trying to point this out for years. Word got spread that all M4A1s have SOCOM barrels and everyone assumed that included all Block II uppers.

Clone correct then SOCOM barrel
But...
Barrel thickness and longevity I do not think support each other. Barrels erode from inside out.  
One could say a thicker barrel retains more heat and a thinner barrel sheds heat faster. So thinner could be the way to go.
Once a barrel looses its accuracy via erosion its worthless to me.
But then again..
Thicker barrel  means it will go longer under extreme heat before catastrophic failure (warping with bullet launching out the side.)
Reason why SOCOM went with it.. (for high heat full auto fire expectations)
Accuracy:
I have not found SOCOM barrels more accurate at all, over a standard barrel, Just more weight.

If you are going to run suppressed or full auto or both then SOCOM would be the best choice
but for semi-fire only, Id go with a normal one.
Link Posted: 12/27/2017 4:40:07 PM EDT
[#10]
Would also add that I haven't noticed a difference in accuracy between my Colt gov pros and Colt SOCOMs. They're all tack drivers. Obviously the SOCOM will remain more stiff from barrel extension to gas block under flex tho. But probably too marginal to matter.

Was definitely disappointed in the accuracy of my BCM SOCOM barrels (plural), though.

I prefer the SOCOM barrel for its heat synching properties. Pezboy prefers the lighter weight profiles for being an overall lighter rifle.

I think they both have their merits. Pick which you like and roll with it. The heat synch thing is a peace of mind thing for me, because as we all here should know, heat is the main killer of barrels. Followed by heat cycles/flame cutting etc

My RIS II FSP has a government profile Colt 14.5" barrel, and it is still clone  correct. Of course I bought the rail back when DD was selling them to the public and bought it in black, but I really could care less. Both were issued, so falls under clone profile.

I'm honestly about ready to shove a 14.5 mid under the RIS and not say anything

I have 2 of the older RISII rails with the fatter profile and lightening holes and neither have a date. Made in Savannah Ga. with a flatter finish than my newer RISII.
There have been several versions of the RISII over the years.

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.

Also, this will not be a forum for discussions.  We will refer back to ARFcom and other sites for discussion.  This is a curated reference site.

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

FWIW, I'm dangerously close to popping off my 14.5" M4 profile barrel on my Block 2 and putting a spare SOCOM in it.  The primary reason is the annoying POI shift when I put a can on it (repeatable, and just due to the weight of the can).  If end up pulling it off, I'll let folks know here, as the price would be more than fair.

Pic thread (might be a repeat)...

As far as short barrels go, my testing and that of others has shown the Colt is hard to beat.  SOCOM is preferred, mug Govt prime is okay too.  BCM has fallen off.  I think those are FN barrels ??  LMT is strong and DD has really improved and impressed lately.  They took gas port size and other feedback, and since Aug, they have produce a very nice 10.3, 14.5 and 16 inch.

Nice. You'll love the A5 system. I have some LMT MWS and KAC SR-25 .308 tubes I use with Sprinco green springs and A5 length buffers and they're awesome. You won't notice as much with a carbine gassed barrel, but with midlength guns it's very smooth and flat.

Not really clone related, but how sweet would a RIS II look with a tan-odized upper? Scored a bunch of these. Tan anodized uppers are almost impossible to find, it seems. Pretty much the same as the FDE anodized rifles Colt released a few years ago. Keyhole forge uppers.

Okay, so I broke down and bought a new 14.5 govt contour which is getting shipped off to ADCO for a pin/weld with a SF4P. I'm fairly certain that once the FH is on I can still put the barrel on the upper receiver and install the handguard without any issues since the FH will be perm'd at that point. Right?

Or should I assemble the upper receiver and then send it off?

Yes, as long as the gas block/FSB is installed before the 4 prong is pinned, you can still assemble the upper.

ETA: Oops, and the barrel nut.

Tell me about it. They went right on the EE because they were 7.62 handles and I don't have a use for them. Lol

Make sure the barrel nut and gas block are on the barrel before it is pinned.

Was definitely disappointed in the accuracy of my BCM SOCOM barrels (plural), though.

I prefer the SOCOM barrel for its heat synching properties. Pezboy prefers the lighter weight profiles for being an overall lighter rifle.

I think they both have their merits. Pick which you like and roll with it. The heat synch thing is a peace of mind thing for me, because as we all here should know, heat is the main killer of barrels. Followed by heat cycles/flame cutting etc

That's odd. My Colt SOCOM barrels are the most accurate chrome-lined barrels I own, without question. They're known for this. Molon had an accuracy report thread on it, which I'm sure you've all seen.

Not gonna lie. This has crossed my mind more than once or 100 times.

Interesting. That's the first I've seen the newer labels. Thanks for the pics.

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.

Also, this will not be a forum for discussions.  We will refer back to ARFcom and other sites for discussion.  This is a curated reference site.

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

Very cool. I won't volunteer them, but I know there's a couple guys in this thread with the knowledge base to help you out.

Pic thread (might be a repeat)...

I say go for it. Swap to the SOCOM barrel.

I think you might've misread my comment brother. I was disappointed in the BCM SOCOM barrels' accuracy. All 3 of my Colt barrels are tack drivers.

Yup. I sure did.

But, yeah, I've heard the BCM SOCOM's weren't all that great as far as accuracy. I'll stick with the Colt's.

Question for the hive.

I picked up a colt 6920 socom with the 16" barrel and was looking to turn this into a block II clone.  I got a DD RIS (fsp) rail and was wondering if I should have the barrel cut down to 14.5 or just leave it at 16"? Will it look funny with 16" coming out of the RIS rail?

Any thoughts are welcome and appreciated.

Leave it at 16" or replace the 16" barrel with a 14.5". If you cut it down, it will no longer have the step down at the end of the barrel. If you have the step down added, it will no longer have some of the markings and will have to be refinished.

Funny thing about clones is that there are exceptions based on ATF/state law on what we can/can't have.  Hence your state may allow you to have an SBR but then you have to pony up another $200 and a long wait.  Cutting a down to 14.5" as stated has its own problems.  A 16" bbl is acceptable as having a SF3P over a SF4P.

A 16" barrel is acceptable?

I think a big part of a Block II is having the correct barrel, which includes profile and length. You can only take so much away before it's not a B2 anymore. I would either have ADCO cut it down to 14.5", add the step back in and refinish it, or just do what I would do and go with the better and even more correct option. That is to sell the 16" barrel in favor of a factory 14.5". That way you're doing it 100% kosher and get to keep your barrel markings.

If you ask a fair price you won't have any trouble selling the 16" SOCOM barrel. On the other hand, you will more than likely pay more for a 14.5" SOCOM barrel than you'll get for the 16" version, unless you score a deal on a used one.

To answer the other question of will it look funny with a 16" barreled RIS II upper, IMO, yes. Hate to be the party pooper here, but the 14.5" would look MUCH better. The bright side is that you've already got the correct lower.
