You might try adco for barrel fluting.

Teh barrel is already pretty light, there isn't much you could take off of it.
Most the weight is in the bolt, gas system, and receiver. [ETA] referring to Tavor. The AUG can have a bit shaved off the barrel if you really want. |

can either one be cut to 14.5" w/o messing up the gas system and without going below 26"?
for a surefire flasjhhider mount. |

I had adco turn one of my barrels down .625 if memory serves. I think it took about half a pound off.

With the Tavor you might be able to get the barrel to 14.5 and keep the overall length 26" if there is an extra thick butt plate available, but it's already a long LOP so I don't think it would be comfortable unless you have really long arms. |

Yes you can cut down a Tavor barrel as long as the flash hider you use gives you a minimum barrel length of at least 16.5 inches in order to maintain minimum overall length. Many guys have already done it and I haven't heard of any function issues ...

The factory 14" AUG barrel has a differently sized gas port than the 16" and 20"

The rule for SBR is barrel no shorter than 16" and must be an overall length of 26" right now my 16" Tavor as she sits is 26.25 I believe. Leave it be.

i was asking in technical terms, if a permmatach job is too short for the gas system on either gun, assuming we all understand the NFA

FYI, the Styer AUg should not have the barrel chopped- it runs on a narrow gas envelope and it seems to have issues with the barrel being chopped (as mentioned, gas ports were drilled at a 45 degree angle on the 14.5" abrrels)
The Tavor should be OK- the standard CTAR Tavor has a 15" barrel, and as I recall the X95 has a 13" barrel and uses the same gas system, so in theory you should be good to go. Of course, the best bet is simply to call IWI US and ask them. |

Of course, it is hard to say for us as no one really has therem here. |

Minimum overall length (OAL) is what gets you on the Tavor. For example just reducing the thickness of the butt pad will drop the carbine into the NFA region even if the barrel is untouched.

Why bother ? 1.5 inches is not enough lenght for the trouble!

Why bother is right.
Even with the longer Smith Enterprise Vortex the Tavor is still shorter than an AR15 SBR carbine -- and retains the 16" barrel which is ballistically superior to anything shorter.

Exactly why I sold my ar pistol, Aug was shorter and retained the advantages of 16 barrel

You also need to look past barrel length; look at how long the rifle extends beyond the pistol grip and compare a 16" bullpup to any runt gun, er, SBR or 14.5" AR and the the bullpup is definitely shorter (unless you're using something like a 7" barrel or so, and even then it might be a toss up).

Some butts are longer. I think the basic M4 type stock is like 7" long and collapses flush w/ the back of he RE and w/ that in position 2, a 9-9.5" barrel would be just about 26" |

I cut the barrel on one of my MSAR E4's to 13.5" and perm-attached a Noveski Flaiming Pig bringing the OAL to 16 1/8". I did it just for the hell of it and to see if it would work without any modification to the gas port (and because I had an extra barrel). It runs just fine, in fact it runs 100% with zero gas port modification. That may be because the flaming pig produces a fair amount of back pressure. My guess is if it works on the MSAR then it would work on an AUG without modification.
