2/5/2004 6:06:14 AM EDT
We are offering our 16" chrome lined pre ban 1/7 twist, 5.56 chamber, 4150 steel M4 profile barrels for a group buy. These barrels have the standard parkerized finish. They have standard feedramp cuts and a cast front sight tower.

If we have 20 people sign up, these barrels which are usually $225.95, will be only $199.95 + shipping.

If 50 people sign up, the price drops to $185.95 + shipping.

There are plenty of reviews on this board on these barrels and we are confident that the end user will be satisified.

Barrels are stamped: CMMG MPC 5.56 NATO 1/7

CMMG does offer gunsmithing, so if you decide you need extra work done like having a post ban legal brake installed, lug shaved and barrel reparked, we can do that.

Please post here for any other info.

Is getting a forged front sight base an option on these? Thanks.

Also, can we get on the group buy if we purchase a whole upper??

by "standard feedramp cuts" you mean non-M4 ramps, yes?

i'd also like to know if a forged front sight base is an option, because that is the one thing keeping me from jumping on board.

1) Who makes this barrel?
Barrel is made by DPMS exclusively for CMMG. You cannot buy this barrel directly from DPMS.

2) Does it have M4 feedramp cuts?

3) Is it made from 4150 steel as indicated above?
I can only take CMMG at their word that it is in fact 4150 as I do not have a non-destructive metalurgical test to confirm thier claim.

4) What other parts does it come with? Front sight base, sling swivel, gas tube, delta ring, etc.
FSB (pre-ban with bayo-lug). The guy at CMMG threw in a sling swivel installed for free, but I paid full price and he seemed to suggest he was doing me a favor. This may be something BigAnt can negotiate with his deal). Front hanguard retainer. Threaded barrel (no muzzle device). Barrel nut.

Assuming you have and are using M4 handguards, to install this barrel on your upper, you will need:
Delta ring assembly (~$10)
Gas tube (~$3)

If you don't have a bolt/carrier for your upper already, they typically go for ~$90.
Pre-ban can put whatever type of flash suppressor they want (usually ~$35).
Post ban people have a selection of brakes available.
I chose a fake A2 brake from Kurts Kustom. ($35)

Get some silver solder paste from Moses and a MAPP torch from the hardware store and do it yourself.

Hope this helps. Someone who bought this barrel

This is from CMMG from another board

They have standard A2 cuts. The M4 cuts are added to the barrel/receiver after assembly.

I might be interested if the time frame is right. When are we talking on the group buy?

I wwould like 1 of these without the cutout for the grenade laucher attachment.

As of now, forged FSBs are not available.

If you get in on this group buy on barrels, we can carry the savings over to a complete upper (-$25 or $40 depending on how many sign up).

ntxyankee, the feedramp cuts are in the barrel extension--where the bullets chamber. We only have the profile pictured available.

The group buy is open. If you want in on it, please post here. We already have 7 people sigened up.

i'm in. i'll just have a forged FSB put on afterward. the price is good enough that this is about the only way i'm going to get a 16" chrome-lined 1/7. i think i would've like an HBAR profile, but beggars can't be choosers.

are you just going to let us know when and how to do payment? and how long will you wait until you place the order or whatever? basically, will you just start when you get 20, or will you wait to a certain point?

how much with a flattop uppper? How much time we got on this deal?
CMMG  [Dealer]

We plan on running this until February 20 and then start taking payments.

If someone wants a complete upper with bolt, carrier, charging handle and M4 handguards, it would be $474.95.

so, if you don't get 20 people, the price stays at $225?

I'm in...IF we can get some more people in on this and if CMMG and I can work out a good price on the following:

1) Shave/cut the bayonett lug and whole top of the FSB (leave just the gas block). I don't need the end cap or the barrel nut either.

2) Install a new FSB out at the normal "rifle length" ala dissipator style. I'll supply a forged FSB (it will need the front sight post & spring from the one that was ground off).

3) pin on a "thread protector" (I can suppply one of needed).

4) Install it on my upper with my FF handguard (I'll send to you).

- Price?


2/14/2004 9:02:10 PM EDT
CMMG: Is that price(474.95)for a headspaced, test fired flat-top upper complete? Man, thats good. Is this barrel chrome lined? Thanks.
2/14/2004 9:03:35 PM EDT
Oops; I just re-read the 1st post again. I'm in; can I get more than 1? When is payment due?

WARRIORSOCIOLOGIST-Shoot me over an email and I will work up a quote for the described upper. I actually have one in the works that is very similar.

TEMPLARKNIGHT-We can do that on a complete upper. These are chrome lined.

footrat-I don't anticipate it being a problem getting the 20 barrel order.

What are the odds of getting 50+ barrels in this buy. I'm very interested but I sure like that price better.

Is it reasonable to ask how many are spoken for?

... I'm in for three, if I can take delivery within 30 days.

What if any difference from this barrel as opposed to a Bushmaster 16" heavy barrel . I'll soon be building my own and wondered if this would be a better option than the Bush 16" heavy barrel complete w/ gas tube, handguards, shields, delta ring, sight, for $209?

Bigant  [Team Member]
2/18/2004 10:32:31 AM EDT
Well this is a 1/7 twist barrel....and it is cut to look like the M4 profile if the bushy is 1/9 than yor getting a different twistin the barrel and if you want it to look like the M4 you'll have to have someone turn the its your preference

bob34thAPS  [Team Member]
2/18/2004 10:53:21 AM EDT
Well I guess that about covers it.
I picked up my first AR three weeks ago and fell in love with it the day I took it to the range.
So I'm building up another but want a 1:7 twist 16" I had thought the Bushie was 1:7 also ,someone gave me the wrong info.
sharpshooter33  [Team Member]
2/18/2004 12:35:30 PM EDT
yea Bushies are 1:9. You gotta do some shopping to find a 1:7. My favorite is 1:8, but that's a real rare one to find. 8-) I'd rather have the 1:7 thought. Your already losing velocity with 14" or 16" so the twist helps stabilize.

I just received this from Bushmaster tech.:
The only 1 X 7 barrels we carry are the pre ban 20" A2 Government barrels and 14.5" M4 barrels that we have over runs on for military contract work.
