I have an AR I am putting together and have been looking for a good 14.5 barrel but have not come across a good deal. Then I remembered I have a nice LMT 16" M4 barrel with a phantom FH that came off an AR I bought a couple of years ago. I am thinking about having ADCO cut it back and reattaching the FH for a 16" overall. Could it go all wrong with the chrome where it is cut? Would the gas system need to be changed? Is there anything else that needs to be modified when you cut back a barrel I am not thinking about? Thanks

Have you asked Steve yet?
Link Posted: 3/11/2006 11:58:49 PM EDT
All you have to do is send it to ADCO,Steve has done two C/L barrels for me and there great.Not only no difference in accuracy but you cannot see the work. You should think of upgrading your F/H now!
Phantom appx 25.00,Vortex appx 45.00.The Vortex is the shitz!

I know ADCO is one of the best. My question was more about the barrel. I spoke with someone from another store long time ago that said he would not cut on a chrome lined barrel. I see so many people here on AR15.com that have cut back ther barrel. I thought if someone has had a problem they might chime in.

Edit to add: demusn1979, I like the way the Phantom looks a little better. Is there any benefit to having the Votex? If it was lighter or better in any way I would be in for a new FH. I looked at the flash test and did not see much (if any) difference.

I believe the answer to your question is yes.

If he didn't explain why he would NOT do it, how do you know he had a technically valid concern?

Chrome is just like every other metal. The correct cutting tool application will do a good job, the incorrect one won't. It's not some mysterious, super-hard unobtanium that can only be properly cut at Colt and Sandia National Laboratories.

Sent a barrel to ADCO and was very happy with the communications, workmanship and fast shipping. I wanted to send my .45 to ADCO to install a dovetail sight on the slide, but was told they didn't do .45 work. No problem, and I appreciated the honest answer. Point is if they have reservations about performing the work, they'll tell you. If they don't say anything, it's implicitly expressed that they can do it, and can do it well.

i have quite a few bbls. done by the guys over at adco and not a single problem.


there was a thread with like 8pgs of chromeline cutting not too long ago in adco's forum with all the rra faux flash hiders being cut off. didnt see not one complaint in there.
Link Posted: 3/12/2006 6:27:55 AM EDT
I had them cut my chrome lined barrel and have no accuracy issues at all. I think they could have dressed the cut up a little better but the accuracy is still great.

The guys at ADCO are known for cutting them just like you want.
Wait a minute, that didn't sound right
Oh hell you know what I mean...
Link Posted: 3/12/2006 11:26:22 AM EDT
That all good news. Is there any thing else that needs to be done when you cut a 16" to a 14.5? Maybe to the gas system?

is the barrel setup for a carbine gas system or a mid length gas system now

ETA: +1 for ADCO I wouldnt hesitate in sending anything to them
Link Posted: 3/12/2006 11:40:40 AM EDT
For you guys that had Adco cut a barrel how did the crown turn out? I know from my old varmit and benchrest days that if the crown wasn't done just perfect the grouping would go right out the window.

It is a 16'' M4 carbine.

If I was going to let anybody do it, it would be ADCO

The picture comparing the two is deceiving because the Phantom is on a pencil barrel and the Vortex is on an M4 profile barrel. I always thought they were more or less the same diameter (outside). Other than the slight performance advantage of the Vortex, I think the Phantom is fine. I've been very pleased with mine. I've used many of the different versions too.

I'm not knocking the Vortex, just saying the picture is not very honest.

I did not notice that was a lightweight barrel.

They are about the same diameter, the Vortex has a thinner (Looking)profile.

I sent my 20" bare muzzle Bushy HBAR to ADCO. I had it profiled to med under the handguards, shortened to 18.5 and standard threads cut. What I got back was beautiful, the park job was
perfect. I just shot it the other day and accuracy was just as good as before , plus the gun handles much better. ++1 for ADCO!

you aren't saying you had work done on this particular barrel, are you? it looks like a full 16".
Link Posted: 3/12/2006 4:09:37 PM EDT
I prefer the Vortex because it screws down flush with the muzzle and it's easier to clean, IMO.

These two were cut and pinned,Thanks Steve!

So no changes to the gas system needed?
Link Posted: 3/12/2006 5:47:25 PM EDT
No changes and no problems.Both are 100% reliable.

I had a 24" vmatch cut, crowned and threaded at 18" by Adco. No problems at all, shoots as well or better than before.

No, no changes to the gas system necessary.

I would never have a chrome-lined barrel cut.
But if I did, I would definitely have ADCO do it.

No - I just prefer the way the chrome goes smoothly into the crown with a factory coating.
When you cut it it stops abruptly. I can't help but think this compromises the anti corrosive properties somewhat.

I have never seen any problems with gov contour or hbars. I have seen problems on pencil barrels. Probably has to do with mass and heat dissipation, and not having it done by Kurts or Adco.

It was a pencil barrel I was talking about with the dealer a while back. On ADCO's web sight I selected the $65.00 cut, rethread and the $25.00 for permanently attaching the muzzle device. Is that all the charges? Or do I need to pay them more for taking off the FH before they cut it?
Link Posted: 3/13/2006 9:06:21 PM EDT
Chrome flashing is super hard(60+ rockwell as far as I know) but its so thin its a breeze to cut
