Ballistic Advantage 6.5 GrendelReview by IPDAILY
I was hesitant to purchase this barrel because it was listed as discontinued.
I'm really happy i did end up buying it.
Was one great decision. I wanted to replace my barrel because the groups were all over the place at 100 yards. I was 1.75 to 2 inches with flyers. The old barrel has a 400 dollar guaranteed MOA or less barrel at 100 yards. No matter what I shot that barrel did not perform. I hand load and was disappointed with my results, that is until I slipped in this barrel. Went to the range with some new hand loads and some Hornady 123 Black. I was blown away by this barrel, and the groups i'm now getting. 3/4 to 1.25 groups no matter what I'm shooting at 100 yards. 200 yards they open up but not too bad 1.5,-2.25 inches. I didn't want to write the name of the manufacture of my old barrel but It begins with N and ends with an E. Ballistic Advantage is now my new go to barrel manufacture. (Posted on 10/31/2018)
Perfect barrel for my Grendel pistolReview by Juan
This barrel is amazing quality for its value. Not only did I get it on sale, but I got it during the sale that BA threw in for free an assembled upper with the purchase of the barrel @ $215 shipped! Such a great deal. It eats my wolf steel ammo ALL day long shooting ~ 1" MOA with a brownells BCG and E-lander mags, no malfunctioning at all. It shoots sub MOA ~ .75" with Hornady SST and ELD black ammo. I don't handload, but I'm sure I could tighten them up more. I couldn't be happier with this build. I am saving up and eventually will buy an 18" SPR 6.5G barrel for a rifle build, but I'll wait 'til it's on sale or BA offers me a great deal again ;) Thanks a million BA for offering such a sweet barrel!!

Lessons learned, Max OAL 2.235"Review by Chance
My barrel has an extremely short throat. Most bullets need to be seated to an over all length of about 2.235" for best accuracy and pressures. This affects powder capacity slightly.
If accuracy is not what you expected. Reduce load by a couple of grains set OAL at 2.235 and work back up. Accuracy will improve drasticaly and extreme spread will shrink. Able to obtain .3- .5" groups this way. My barrel loves Hornady 100 grain ELD Match bullets 33.5 grains CFE223. 2505 fps from 12.5" barrel. This is what works for me but may not be safe in your pistol or SBR.
I do not recomend wolf bulk ammo for this barrel. Bullets are likely to stick in lands and be hard to extract. Forcing action open can leave bullet stuck in lands and spill powder into your action. It is a Match barrel treat it that way and you will be pleased. (Posted on 11/19/2017)
AwesomeReview by Shawn
I set up an account just to write this review, which will be short I bought this barrel to build a telscoping maxim stock “SBR” to have a handy rifle that bucks the wind well because I live in North Dakota and its windy as heck at all times. I broke in the barrel and then shot for some groups to get it zeroed. Well it groups just under an inch with 129 gr LR accubonds which expand reliably all the way down to 1300 FPS. I now have a SUB MOA “pistol” that is handy as hell that doesnt go transonic until 800 yards. That’s badass.

The one downside is that my particular barrel doesn’t eat wolf ammo at all. Stuck cases galore. Nothing I couldn’t mortar the weapon to dislodge but, Kind of a bummer. That said, this isn’t a SHTF rifle. It’s a handy hunting rifle for me and with brass case ammo its been 100% reliable. The noses of the bullets arent being damaged upon entering the chamber either, which is something I have ran into with other grendel barrels. I’m using an Odin Works BCG and it’s working great. Great stuff. (Posted on 11/10/2017)
Excelent in every way!Review by Chance
I have over 20 years experiance as a professional gunsmith and I have been building 6.5 grendel AR-15 rifles and pistols for years now. This was the most trouble free barrel I have ever installed. Gassing was perfect. Brass lands in a neat pile at 3 oclock. No feeding problems when good mags are used. Quality fit and finish is excellent. Accuracy is hard to believe. Contour is a perfect compramise between stiffness and light weight. 100 grain bullets at 2500 fps and a little more out of anything lighter. You do the math. Compare the 6.5 Grendel out of this 12.5" barrel to rifles in other callibers. Worth every penny! (Posted on 11/2/2017)
