Planning on building a true 16” with pinned/welded muzzle devise. Looking for thoughts ideas on barrels.
Right now leaning toward Faxon 14.5” pencil with pinned/welded brake.
Any thoughts ideas would be great. Thanks

I bought a 16 inch pencil. Skinniest barrel I have ever seen. It shot horrible for the first couple hundred rounds but now it shoots 1.0-1.5 MOA after a heavy break in period. Be prepared to spend a few bucks breaking it in.

I would be shocked if that break in period had anything to do with the thickness of the barrel walls.Quote:

As a matter of fact, this is going to be my next barrel for my WWSD type built.
I have a Faxon Firearms 10.5" pencil barrel on my SBR built and it is easily a 1.5 MOA barrel. With Hornady America Gunner 55gr. HP bullet, it has turned in a few under that. This barrel has also turned in groups under 2" with Lake City M193.
Besides Faxon Firearms making an accurate barrel, their pencil weight is one of, if not the thinnest/lightest barrels out there. So, in my opinion it's the best of both worlds. Light and accurate.
Was that a Faxon, or a nitrided barrel? Was the 'heavy' break-in just more rounds down the barrel, or was it also additional cleaning?Quote:

No knock against Faxon. Have a BCM pencil barrel in 16". Great barrel. 1.5 moa. Chrome lined cut rifle average barrel but shoots well for what t is.
It should be noted these factory installed pinned/welded muzzle devices are low profile and will allow installation and removal of a .625" gas block without removal of the MD. This will be the barrel I use for my next LW build.Quote:

The BCM barrel is 20 ounces, chrome bore
The Faxon barrel is 17.5 ounces, nitride bore
Both use a .625” gas block, the BCM barrel is about $80 more.
Thanks for the ideas and advice. Gotta do some more looking now.
These really are THE two barrels for a 14.5" LW build IMO. I had been set on BCM for a while but ultimately decided I'll give the Faxon a shot because I plan to do an ultra-light as in CavArms ultra-light and want to shave that extra 2.5 ounces, it would also be my first nitride barrel (which I've steered clear of intentionally up to this point and figure its time to checkout), the extra coin isn't a big for me as I am weak and will eventually end up with an ELW as well.Quote:

I’ll admit, the nitride steered me away from the Faxon barrel.Quote:

That has steered me away from ANY barrel that is nitrided/QPQ/Melonited. Sorry, I just ain't on board yet and may never be. Go chrome or go home.....YMMV.Quote:

I'm probably wrong here but it feels like the same tired arguments against the use of polymer in firearms.
PS. Sorry for continuing the thread derailment

Chrome plated > nitride > bare bore
But then, I have many bare barrels, so . . .
For those of us who actually kill barrels, chrome-lined offers superior wear resistance over nitride.Quote:

Again I agree that chrome lining is superior to nitride in terms of resistance. But only if you don’t have the option for semi automatic fire. Any engineers or technical guys want to elaborate? I’m not a expert by any means just regurgitating some answers from a YouTube Q&A from a former Faxon spokesperson.

I also don't use lightweight barrels. I prefer intermediate weight barrels, basically the same weight as gov't profile but with the mass moved back towards the chamber, like the N4, hanson profile ect.
Anyway, if you really want to learn more about the subject I would look for the original Aberdeen Proving Ground documents in testing various treatments and plating on everything from small arms barrels to auto cannons to 120mm smooth bore tank guns. I would put more faith in those documents than manufactures claims that nitride is "just as good as". You dont see them thrown around in the usual chrome vs nitride because they are technical papers that are hard to interpret.
Long story short, the loosening of the barrel extension is what steers me awayQuote:

Is that even an issue?Quote:

Me too. I've never owned a rifle that didn't shoot better than I did, pencil barrel or otherwise.Quote:

Faxon says nitride is normally more durable than chrome BUT at extreme temps chrome is more durable than nitride.
I run a BCM 14.5” pinned pencil barrel, chrome lined. Accuracy wasn’t a top priority for this build, otherwise I’d run a heavier profile nitride barrel. This was bought about 5 years ago when there wasn’t a lot of real world feedback on nitride.
No complaints re:BCM but between the two, I’d choose Faxon.
As for the small arms stuff alot of the links I have from dtic.mil arent working anymore. Maybe they'll get them working soon?Quote:

I think this one should work, but it also might kill your eyes.
