Great balance - but do the break-inReview by Wes
Acquired to replace a ponderously nose-heavy full-on A2 profile barrel. Couldn't be more delighted with that aspect of it. Literally shaved a full pound off the gun & much better balanced now.

This is not a gamer/range toy, but meant to be a working gun & shoots MILSPEC ammo I own a ton of. Don't know whether I got an anomaly or not but the break-in has taken notably more time & ammo than thought. First 120 rounds it seemed to be one of the worst copper-grabbers I'd seen. Note that I DID go by the company's recommendations stringently, but the bottom line recommendation I'd make is this: Continue to assess on your own. What's the patch really look like, be honest. What's the bore look like, etc. There is no magic number. So do a really good break-in & it should pay dividends in the long run. (Caveat: Don't know if the more spendy barrels are "lapped" or of any finer finishing but this one is a keeper & getting a bit better each time.)

The result is that (exhale after 160 rounds, finally) I have a better balanced barrel that lets my old eyes shoot irons to MILSPEC with MILSPEC ammo, and will do 1.5 MOA with MILSPEC ammo through the ACOG. Again, for a working gun with that ammo I'm delighted and the gun handles overall SOOO much better.

Thanks for a fine barrel. (Posted on 7/27/2018)
Excellent barrelReview by Matt
Been very happy with this. Initially purchased for my first AR build, it has been more impressive than the "general purpose" barrel I expected it to be. Combined with a Ballistic Advantage BCG, gas block/tube, and VG6 Epsilon, this is a set up that is hard to beat! Next on the list is the 18" fluted SPR and the free lower receiver!

Outstanding!Review by Russ H.
Just used this barrel for a build - I'm very happy with it! Not too heavy, not too light. Mid length gas reduces recoil and works better than carbine length. This is my third BA barrel and I haven't been disappointed yet. Very accurate! Buy one, you won't regret it! (Posted on 7/26/2017)
