300 blk barrel, which one?

[el_chupo_]

I am in the market for a .300blk barrel, and am having a hard time making a decision.

First, I am not sure what all this will be used for, but it will probably have a red dot. Right now the plan is majority subs, with a can (Saker or Omega) and maybe occasionally supers, but no real purpose on that front. This will be replacing the barrel on a "range toy", so lets focus there for the build.

If it matters, I already have a 12.5 556 SBR, and have been eyeing the idea of an 11.5 as a second SBR, so the 5.56 is covered.

The upper it is going on has a 10" rail that I was able to mount a Saker or Omega on (outside of the rail) but it is big enough for the can to go inside. That is not a goal, but a possibility. Of course, could always swap rails in the future too, but because of that I am primarily looking at 10.5" barrels.

I have a Seekins .750 adjustable gas block to go on it.



I am looking at the following in the mid-higher end range ($200-300)

Noveske 10.5 https://dsgarms.com/nov07000034
Seekins SS 10.5 http://www.capitolarmory.com/seekins...ch-barrel.html
Mega Arms 10.5" (416 SS, nitrided) http://www.megaarms.com/ar-15/ar15-b...ckout-barrels/

Then on the cheaper side ($150 or under) there are

DSG 8.5": https://dsgarms.com/dsghbarrel-300-001
Faxon 10.5: https://www.rainierarms.com/faxon-fi...ht-barrel-10-5
SOLGW 9": https://sonsoflibertygunworks.com/co...ant=3083520321



I am not finding many (if any) reviews on the DSG, SOLGW, or Mega barrels, and very little on Faxon. Seems like most of what I can find is around Noveske, Seekins (older posts), and KAK barrels on other sites, along with stuff like Radical, PSA, and a few others.


I know I dont really care about velocity differences, especially with subs, but I know it may one day become the HD rifle just for the extra quiet (once reliability is established), so I am not sure where to go...

Thanks - but why would I go Aero/BA vs anything else I have listed?

They are more expensive than multiple options, while still being 4150 steel with QPC coating, which has me a little hesitant.

Do you have any experience with a specific barrel?

I have the SOLGW barrel bu haven't gotten much time with it yet other then a quick function check. It train well with superbug haven't tried it with subs or suppressed yet.

I have 5.56 barrels from Faxon and AP / Ballistic Advantage, and have been happy with all of them. Unfortunately those two companies seem to have chosen the silly "GI" profile for their short 300BLK barrels, and I would skip that.

If you decide you want one anyway, AIM sells the Faxon barrel with a pinned gas block:

The Mega looks like a good barrel at a reasonable price. I can't see spending Noveske money on a short barrel for a range toy.

FWIW, I have 300BLK barrels made by AAC, DS Arms (not DSG Arms), and AR-Stoner (Midway-USA house brand), and all of them have worked fine, with no perceived accuracy differences so far. I haven't done extensive testing on any of them though - the ammo drought coincided with the part of my life when I had shooting time, so they didn't get used much, and now that ammo is more readily available I have less time to shoot.

It could be argued at 10.5", 5.56 makes just as much sense.

The original Honey Badger used a 6" barrel, while the new one uses a 7" barrel.

The 7.5" is a nice configuration for 300BLK, especially for suppressed use.
