Relocating Gas Port

OldState · #1 02-13-11, 20:41

"Relocate Gas Port For moving Gas Port Location $35.00
If you want move your gas port from the rifle to MID, or MID to CAR. If the new location needs contoured, the contour fee/job must be selected."

This is a service ADCO offers. I am looking to see if there is anyone who has moved the gas port from carbine length to mid.

I am looking to get my first AR and am probably going to get a LE6920. My only issue has been the carbine length gas system on the 16" barrel.

Is this an option to consider? Also, the wording could imply you can only shorten a gas system.

Any help would be appreciated.

I wouldn't do it.

If you want Colt quality, but in a middy then look at BCM, DD or Noveske.

What is the issue with a 6920 that you would consider relocating the gas port? By the way, the cost is really north of $400 as the Colt barrel will be a total loss.

I have been in the research phase for a month now and happen to come across this the other day.

I've found several debate regarding carbine and mid length gas system. The mid length seems to be the overwhelming choice but the 6920 is often recommended despite the carbine length gas system.

After seeing this service I was curious why moving the gas port hadn't been mentioned much. It would seem to be an inexpensive way to have the best of both worlds if it was viable.

Get the Colt 6920 and dont look back, the carbine length is just fine.

Save up for a second rifle, or upper in midlength.

I'd get in touch with Red Jacket Firearms. I'd bet they can install two Gas Blocks with proper valving so you can switch back and forth between carbine and mid-length actions.

Just curious, since you've been researching for a month, what is the consensus you've discovered.

The only surprise here is that it didn't happen sooner.

If you can dream it, we can build it!

As previously stated, mid-length much better than carbine but le6920 is still the best gun. That is what I've gathered.

As for all the hating on Red Jacket and the show; I think we should be happy that there are any gun related shows on channels as popular as Discovery being that the entertainment industry is 90% anti gun.

First AR? Get the 6920 and never look back. Then you can look into fine tuning gas systems as you become more skilled and knowledgeable.

HA!

OP, if you go with a 6920 just stick with the carbine gas. If you want a mid length, buy a quality mid-length. A 16in carbine gas system may not be the optimal system out there, but its been getting the job done for years. I recommend you look into a 6720, lightweight barrel model, because when you start adding stuff to the rifle like optics, light, sling, foregrip, whatever, the weight adds up quickly.

I'm going to order the 6920 today. This is the first gun I've ordered online. I hope it is an easy process.

As for the 6720, I did check it out but I want the 1/7 twist. I think the 6720 is 1/9(?).

I'm going to try and keep this gun lean as far as accessories.

Based on what you're saying and what I can find online right now I think you may be looking at the CR6720 which does list a 1/9 barrel. What you would want is the AR6720 (maybe also listed as LE6720?) which has a 1/7 barrel, as shown here:

I was looking at the wrong one. I'm just not digging the pencil barrel....

Why not? They are a FANTASTIC choice (might even be the BEST choice).

Being that I don't intend to carry this thing all day everyday, I don't see any advantages in a lite barrel.

For years I have been planning on getting an AR and finally have decided to "pull the trigger". That being said, I originally wanted a precision target gun with a heavy barrel. (since I've been into guns I've always agreed with old Townsend Whelen that "only accurate guns are interesting").

Now I've decided on a fighting gun (at least for my 1st AR). I joined a second club that is into the practical shooting disciplines. My old club always had a precision shooting culture (bullseye pistol, NRA High power, CMP - also skeet and trap...the old fashioned stuff)
I guess that's part of the reason I'm having a hard time wrapping my head around it.

Sure, but when you do (or take a carbine training class), you will appreciate it.

Heavy barrels don't mean that they are more accurate. It just means that the GUN is heavier and thus less likely to move.

Understood. And I don't expect a chrome lined non-free floated barrel to be super accurate...but there are also thermal benefits of more mass. Don't you fire a lot of ammo in a carbine class, etc?

I will give it another look. The price of 6920's seems to have gone up over the weekend. To bad the wife gave me the go-ahead Saturday night.

Uhm no. Thin barrels cool down faster than thick barrel.

Watch gun broker as well. They are sometimes dumped on there.
