Very nice barrel, only complaint is the roll pin for the gas block. Review by Justin
I’d much rather have a solid tapper pin because the roll pins tend to not like being that long going into the channel.

Works flawlessly on my MK18 build (Posted on 4/14/2019)
Great price and qualityReview by Godzproject1
Run this barrel on my MK18 CQBR Block II Clone build and it’s excellent handles 77grain very well and 62 grain all day long and all ranges from 25 ft up to 300 yards and is spot on. (Posted on 1/10/2019)
First 85 rnds out of BA 10.3Review by Anthony
First 65 rnds were on 4in target @50 yards with 62 grain green tips. Next 20 rnds were on 8in target same distance. With 77 gr match Sierra PMC. Considering it hasn’t had its first 100 rnds and it’s hitting 1 inch groups with the 77 gr match, I’m very impressed and anxious to see what will happen with other match ammo 68/69 and 75 grain.
You guys have a strong product and a very fair price. (Posted on 12/29/2018)
An OUTSTANDING barrelReview by Robert
I have this 10.3 on one of my SBR's. It's not a Mk18 or a clone, it's just a bad*** SBR. I wont try to admit I fully undertand barrel harmonics and whip, but with a similarly equipped 12.5" SBR, my 10.3 was definitely a smoother shooter. I also think the GP size on this barrel is .067, which I believe will work well suppressed also. I run it fully unsuppressed while waiting for my can to get out of jail. I highly recommend this barrel. Every BA barrel I've purchased (7) have had excellent fit and finish, and they are very accurate. I own this. 10.3 all the way up to a 18" Performance .308 barrel. I will say it like this. I have other barrels. If BA doesn't manufacture the length I need, like 11.5, I use Daniel Defense. These are the only two manufacturers I use. I will say that my Hanson barreled AR's ar as every bit accurate as DD, which cost a 1/3 more. As the previous reviewer wrote, I believe this would be a good option to your Mk18 clone, if you aren't insistent to replicate as close as possible, by using an LMT. If you an excellent shooting barrel is your criteria for your Mk18 clone, then here it is. Pull the trigger. You will NOT be disappointed! (Posted on 10/9/2017)
Epic BarrelReview by Tyler
This is just a fantastic barrel all around. I'm using it on a Mk18 inspired AR-15 pistol build for myself and with a Spike's ST T2 buffer and Sprinco Red Buffer spring in the pistol buffer tube I was ejecting at 4 o clock. I'm not sure what the gas port size is on this barrel as it isn't in the description but that combo has worked perfectly so far. I also purchased an 18" Stainless mk12 profile barrel and the accuracy between the two is very similar within 300-400 yards. Just very impressed with the accuracy and the recoil impulse with a properly tuned gas system is insane. Especially considering I only have been using an a2 flash hider and not a muzzle brake like a VG6 Epsilon or a Lantac Dragon etc. I'd recommend a Fail Zero NiB-X BCG to match the barrel extension which is using NiB-X as well. They cost around $125 on 2phasttactical. Not a whole lot more expensive than a phosphate BCG at that point with a much better 50,000 round rated, self lubricating, and easily cleaned BCG. Plus the lock up is ultimately smooth against the barrel extension that way. Only way to make the action smoother afaik is with a Nickel Boron or similarly coated charging handle. I have only had the chance to shoot 55gr American Eagle .223 so I can't imagine how accurate these barrels are with a proper match grade round like the Sierra TMK 77gr. Thanks ballistic advantage! I will be sure to purchase more of these barrels when I need to. I got this barrel on sale during Memorial Day weekend for $164 and I couldn't be any happier with it's performance. Be sure to use some aeroshell 33ms when installing and use the proper torque. Lastly check your headspace with your BCG once the barrel is installed just to be ultimately safe. (Posted on 6/27/2017)
