Hi all,
Just wondering what the conclusions owners of rifles with these barrels have come to. I’m building a couple AR’s meant to be of the lightweight variety.
How does the accuracy of these barrels stack up? Does the ELW profile’s taper help mitigate POI shift under heat better than other lightweight barrels? How does it stack up against the very similar “gunner” profile barrels from Faxon?
I don’t have anything bad to say about them. They’re certainly more accurate than I am.
I shoot 2 of them, an 11.5 and a 14.5, both have been very satisfactory for my uses.

What muzzle device are you using on the 11.5? I put a bcm mod 0 on mine and it’s pretty obnoxious.
Some (including myself) have had sub par accuracy with them.
I run a 14.5 and 16”. No complaints either.
No experience with Faxon’s LW barrel.
I like Ballistic Advantage Hanson profile and they have been a good compromise in various lengths.
I had one briefly a couple of years ago that shot horribly. Like 7-8 moa with everything but 55gr Sierra Game Kings, which it shot sub-moa. I gave it back to the owner and he sent it to BCM they replaced the barrel.
I own two 16" BFH ELW uppers and they shoot fine. I’ve gotten 2moa prone on the mag with MK262, SSA trigger and an Aimpoint Micro.
I’ve got a 16" BFH ELW with the Mod 0 Gunfighter comp. It’s plenty accurate (more accurate than me at least), but my dad’s DDM4v5LW upper shoots tighter groups with almost every load we’ve compared. I’ve gotten my barrel warm (continuous fire on a hot summer day but no mag dumps) and it opens up an inch or so at 100 yds, but my dad only shoots his slowly, so I have no comparison.
I have an elw and elwf both 16" middies.
I get 1 to 1.5" at 100 yards with mine. I think it does better then a pencil barrel. The only issue I have is a big poi shift when I throw my suppressor on it, but the shift is consistant.

I have a 16" ELW and 18" Faxon gunner. I haven’t shot them side by side or heated them up to test any accuracy shift. They both shoot the 3gun 55gr load that I use well. I’ve been pleased with both of them and shoot them in 3gun.
I have a 14.5” and I have no complaints with the accuracy. If I end up grabbing a 16” upper I will go with ELW again.
In my case an AAC brakeout.
In both cases I have to agree that the shift in POI is major when a silencer is attached. Also as stated above it is completely repeatable, so not really an issue as for my purposes.
I’m going to try a Warcomp CTN. I’ve been happy with the regular Warcomp I have on a 10.3 but I wanted something a little shorter for my 11.5
16" ELW BFH w/ BCM Comp and 11.5" ELW with Trifecta and Saker556K (almost exclusively).
No issues with either, an honest 1-2 inches at 100yards, depending on ammo (mostly Federal, PPU, and gasp some steel cased Wolf through the 16")
