I have changed the barrel on my NEA 18'' heavy barrel to a faxon 16 gunner series. So now what to do with the spare barrel, thinking of getting it turned down to a lighter profile of .640 under the handguards tand .640 from the gas block to the muzzle and maybe shortening down to 16'' in the view to suppress it later with a adjustable gas block. Anyone been down this path.
A new barrel is getting over $400 now and scarce to source and the way things are going they probably wont be available much longer. I figured the cost wouldn't be more than 1/2 cost of new barrel. Have found a club member /gunsmith with all the lathes and gear will look at it for me, he has built numerous suppressed uppers. Will be a project and interesting to see if the accuracy remains.

I have contacted a gunsmith who has just done a similar job for an AR. Around $175 cost plus extra for ceracoat. The barrel at the moment gives under 1 inch groups with a particular bullet.
if you are a cunning cookie set up a thread offering a swap for the profile you desire
factor in some $ for parkerisation or similar if its not stainless
what length gas tube for the 18 inch barrel and for your 16 Faxon gunner ?
i dunno, but to me it just seems like you are going to end up with 2 very similar barrels...
Both the NEA and faxon barrels are both mid length gas, the faxon is very light and is pencil forward of the gas block. I had the NEA barrel as spare so i figured ill build a dedicated suppressed upper. The faxon barrel is on my E cat gun which i use in practical events, and was just too heavy with the NEA 18 inch barrel.
I got the barrel back after ceracoat and re profile very pleased with the result. it is a lot lighter than previously, So all assembled and went to the range for testing .
After testing and adjusting the gas block with suppressor fitted at 50m i set the target up at 100m.
Settling down careful 3 round group using 60grain hornady softpoint, the first group was outstanding of less than 1/2 inch. Next few groups opened up to 3/4 inch and just on 1 inch and at this stage getting heat mirage off the suppressor. With the armaworx gas block and the adjustment open between 1/4 and 1/2 turn ejection is around 1 meter at 4 0clock and cycling is perfect.
Good result, bet the rifle is much more practical now
Good project and good result, running my 243 dpt suppressor on it will get a stainless blast baffle for it then hopefully cull a few goats.
*Looks at 18" NEA barrel doing nothing*
"Looks at lathe sitting idle at work*
Hmmm..... you would mind posting a couple of pics of yours would you? Nothing to loose, but a lightweight midlength 16" bbl would be a nice project
