Excellent BarrelReview by Paul
Great shooting barrel, excellent accuracy! I shot several different loads through it and they all shot well, even the lighter 55 gr loads. The 68 and 77 gr loads did perform a little better but they should considering it was match grade or near match grade. Average was 1 moa or less with the match ammo so what you what expect. What surprised me was that I was still easily able to shoot between 1-2 MOA at 100 yards with standard 55 grain loads such as xm 193 or federal 223.

My one complaint with the barrel is that I had huge problems trying to thread the VG6 Epsilon brake on the barrel, I still haven't been able to get the last few turns. This after screwing down and backing back out numerous times and using excessive force. I finally gave up when I got close enough to cal it good as its not going anywhere! I'll pull it off down the road and give it another shot maybe using some additional heat as I only had a regular hair dryer although it should have been good enough. Overall great product and will definitely be buying more BA products, next is a stainless barrel! (Posted on 12/23/2017)
The BestReview by DONAVAN
I used this barrel on my MK12 MOD 1 build. I used the military version so my standards were set very high. When I installed this barrel and hit the range I was dumbfounded with how accurate the barrel was. I used 77 grn OTM rounds and had well under a .5" MOA at 100yds. I will be ordering much more!

Simply UnbeatableReview by Robert
The title says it all. I installed this barrel on my 18" SPR build. I used an Aero upper, lower and an NiB BCG also from Ballistic Advantage. The 18" SPR barrel is an excellent barrel, manufactured by skilled craftsmen. This isn't my first "BA" barrel but it is definitely one of my most accurate. (My Ballistic Advantage .308 18" 416R SS Premium barrel is also ridiculously accurate.)
Last last trip to the range on a very windy Texas morning I was able to make 4 round shop groups at .52", .54", .58". at 100 yards. Previous trips on less windy days resulted in BETTER shot groups, but I did not own my calipers then. But I will say that on the say I recorded these groups, it was 74 degrees and we had a 8.9 knots average gusting to 15 knots. That's a 10 MPH constant and a gust at 18.5 MPH. 30 degrees off my lane and I still shot those groups. Using a heavier round in my BA 308 18" Premium I placed 4 round shot groups at .39" also at 100 yards.
The fit and finish of BA barrels are top notch. They have easily identifiable roll marks and they are packed very well. I highly recommend Ballistic Advantage products but specifically since this review is about my SPR barrel, I highly recommend this barrel. (Posted on 5/3/2017)
