You'd probably make out best sending your barrel to ADCO for the work to be done, rather than buying a new barrel. While at ADCO you'd probably benefit furhter by having them also lighten up the barrel under the handguards (for most this would be a beneftit IMO)
That sounds really good and it's not hard to shorten the barrel, but now you just created a SBR and can go to jail for doing so. anything below 16in is illegal inless you have the tax stamp, $200 dollars. I would recomend gettinng that before hacking your barrel to avoind the prison sentence. If the vortex makes it back to 16in your good it just has to be permentaly attached what that means is you can't put it on or take it off. You would have to send it somewhere to be done there is a whole heat and not be taken off thing and other stuff.
Hope this helps with your decision.

Unless you want to go the SBR route, the FH has to be pinned and welded. If it was me I'd get someone like ADCO to do it, but that's because I don't have the tools or the metalworking expertise. YMMV.
I have two 14.5" RRA barrels. One was cut and pinned with a Phantom by ADCO, who did an excellent job. The other was special ordered from RRA with a pinned Smith Vortex. So, you have at least those two options before you.
I sent my LMT 16" barrel to ADCO and had them chop it to 14.5", add the "step" in from of the 203 notch, re-thread/crown, and re-park the whole barrel. They even parked under the FSB (my one issue with LMTs). I perm attached a Smith Vortex to bring it to 16.1".
I am very happy with the results.

that looks really nice.
mind PMing me how much that work cost?
i have a 16" LMT M4 and ever since i got into Midlength uppers, 16" CARs just look really weird to me.

Why would I change anything in the action? :confused:
I run the weapon with an "H" buffer, and I ran that before and after the barrel work.
The only malfunctions I have ever had with this rifle are ammo (had a Brown Bear stick in the chamber once) or magazine related (running very old magazines I had left over from the Army). All of which happened before I got the work done.
I have fired 1200 rounds (500 Brown Bear 62gr, 500 Wolf Military Classic 55gr, 200 PRVI M855) in 3 outings since the barrel work was done and never had any malfunctions or stoppages whats so ever.
First of all I'm no expert but i will attempt to answer your Q's.
1. Yes you can buy a 14.5 all over the place if you can find one in stock, you can also send it off and have someone shorten it for you. I seen an auction on gun broker a while back that would shorten, recown and thread for like 49.95. I will not vouch for their work.
2.If you shorten you'll either have to get a SBR stamp, own a registered machine gun lower or pin and solder the flash suppressor/ comp on.
3. after you shorten the barrel you will lose some velocity=bullet drop=range, however you might gain accuracy, do to less barrel flex.
4. You'll still be able to fire any shelf ammo that you were able to fire before.
5. It highly unlikely that a highway patrol would even notice the barrel length and as long was you follow number 2 your GTG.
6. You will not have to change anything on your rifle after you shorten.
I hope this helps.
