Expo Arms 5.56 NATO Chrome Lined AR-15 Barrel - GOV Profile -Mid Length - 16"

Put about 125 rounds through it the first time out and could have shot all day.

Well I'm shocked, and pleasantly so. Chrome lined and dimpled, which I did not expect for a barrel this price. Took it out yesterday, and with Federal M193 55gr, I'm getting about minute and a half. I shot 5 groups at a 100 yards after zero to see the accuracy, and not a single group went over 2", not using a rest just shooting off the bench. Brother I am more than happy with that for a 2Gun or 3Gun setup. For a cheaper barrel, I'm pretty stoked with it.

Barrel arrived in perfect condition. Fit and finish is flawless. Shot a 5 shot group less than 1MOA first time out with some random 55gr Sierra handloads I had made up for a different gun. This barrel shoots everything well. Some better than others. No regrets buying this barrel. Excellent.

This barrel will shoot. Excellent accuracy with a perfect fit and finish. Gas port is perfect diameter. Mine measured exactly .078" with pin gauges. I feel this barrel was an absolute bargain for the price. Would highly recommend to friends and family. Quality piece.

I needed a decent barrel for a build. I was pleasantly surprised with the Chrome lined Expo barrel. More accurate than I was expecting.
The finish was also great. I already have a few expo rails and parts on other rifles. Never had an issue with anything expo.

Primary Arms ships quick with tracking updates. Awesome! Barrel looks great. I will be testing it this weekend for accuracy. Nice fit into an Anderson upper. Had to tap it in the last 3/8" with a rubber mallet. Now to see how it compares to an SOLGW 16" middy for least picky about ammo and best overall groups. Winner gets a permanent home with me. So far every Expo Arms item I have purchased has been great!

Bought this about a month ago and left a 4 star review based on a visual inspection and fitment to reciever and gas gas block.
Everything was great as expected. Took it to the range on Saturday andshot five 5-shot groups from 55 grain to 75 grain, 4 different brands. All regular off the shelf stuff to sight in and function test the gun. Shooting at 50 yards the best group was .365" and 3 groups were average .875, the largest was 1.2" but four of those were touching at .490". So yeah, it's a keeper. This barrel is fantastic for a "combat" barrel.

I’ve gotten quite a few of these barrels for builds, never any issues and love the fact already dimpled! Always like my chrome lined barrels.

First off I know expo is PA brand but there stuff is TOP OF THE LINE. This barrel is gassed PERFECT. I prefer phosphate finish on barrel and bcg and I'm running both and I can not believe the quality from this barrel and bcg. It's accurate and take my word I shot a nickel sized 4rnd group at 50 with a dot. I can not believe this EXPO stuff but damn 4 o clock ejection without a blue springco is just mint

This is fantastic for the price. Micro groove rifling, concentric crown, dimple for the gas block, chrome lined, and thick magnesium phosphate coating. I am very impressed with reliability and accuracy so far, all that's left is longevity!
