Great buy.


I put this barrel on a new build i did, its amazing. using privi 168 match i was shooting the same hole out at 50 yards, at 100 yards i was shooting 1/4 in groups.

Extremely accurate barrel


first and foremost the barrel is flawless machining is excellent! I broke the barrel in properly and with match grade ammo I'm getting 1/4" 3 shot groups at 100yards! I'm extremely happy with my purchase. Not a better barrel on the market for the money!

Best kept secret for precision rifle build

This BA barrel is amazing for the price point. Shoots well under MOA and fit and finish is perfect. I only buy Ballistic Advantage barrels at this point unless I was to built a light weight 6.5 and then would probably go with BSA. These are the best kept secret for a precision rifle in my opinion. Catch them on sale and you cannot go wrong.

Recently purchased to build LFA10, barrel is super nice. Extremely accurate. Could not ask for better quality.

Awesome Barrel

Has a brushed stainless finish which I married with a VG6 stainless muzzle brake and it matches perfect. Heavy barrel but the contour/profile makes it feel a little lighter when installed. Sub MOA groups at 100 yds and hitting silhouettes out to 600 yds. Performance exceeds price with this BA 308 barrel
