Product Description

Please read break-in procedure on FAQ page

This is our 16 inch Mid Length Gas, light contoured barrel that is Melonite/Nitride treated. Melonite has shown to last 30% longer than Chrome. Please see our FAQ section for more info on this. This barrel has a Wylde chamber which is more accurate, but can still shoot .223 or 5.56 ammo. Barrel extension is torqued to the barrel after treating, due to different expansion/contraction rates. This is the proper way to treat a barrel. Barrel is milspec 4150 steel, has M4 ramps and is threaded 1/2×28. Gas block is .750. Weight is 1lb 8oz and has 1:8 twist rate with 5R rifling. Barrel markings are on the chamber end in order to not effect the path of the bullet. Extensions are left untreated to show that the Melonite was done correctly.

    1.5-2.5 MOA multiple 5 shot groups with super cheap herters steel cased ammo. My DD 16″ hbar does the same group sizes for comparison. My standard AR does the groups 2.5-4″ with same ammo. I’m not sure if the 5R rifling is to account for this, but I am very pleased nonetheless. I am not looking for super tight groups as this is after all a lightweight barrel going on a rifle with just a red dot and iron sights.
    Cycles steelcased fine with stock gi weight buffer. Much more accurate than anticipated. Have yet to custom load some ammo for this but I am pleased.
    I just wish there was a 14″ option to save some weight for my lightweight rig.
    After some reseach, this appears to be the exact same barrel offered on another site for less $$$.

    Justin was great and helps run a great shop here.

    Bought this a while back but didn’t finish the build until recently. Took it plinking a couple of times and it did great. Finally took it out to really test it out today and it started raining! In spite of shooting a constant drizzle, I was able to shoot several 3-shot groups at 75 yards from prone, with a bipod that were under 1/2″! I was shocked. I bought this barrel for a lightweight build and expected 1-2 MOA. Apparently it will do better than that! I also consistently hit clay pigeons at close to 300 yards. Considering that I was using a 3.5x ACOG, I’m truly impressed! (This was with Black Hills 77gr match ammo).

    Fast shipping. Great fit. Still in the assembly process. Will let you know how it turns out once I get it to the range. I honestly cant visually detect the difference between this 5R barrel vs other barrels I have owned. Hearing it described as similar to the Glock design, and holding my Glock barrel for comparison I cant see the similarities in the rifling. To be candid, I am no expert on AR barrels so lets get that right out in the open. Im likely missing something, and the barrel is likely fantastic. The finish is outstanding. Very happy to see someone putting out this hard to find combination: 5R, Wylde, Melonite. Good luck finding it anywhere else. And LIGHTWEIGHT.

    Customer service was excellent and very helpful. Once I finish the build and take it out to the range a few times I will come back and give it that 5th star. So far so good.

    I really like this barrel. It is not particular which ammo gives the best accuracy because it has shot tight groups with every kind of factiry ammo or reloads I have run throgh it. It is one hell of a fine barrel!

    Purchased a complete upper with this barrel. Everything I wanted in a barrel, Melonite, 5R, 4150 CMV, 1:8 twist ,16″.
    This puppy shoots, thought I might sacrifice accuracy? No way, 1/2 MOA @ 100yds. 1.5″ groups at 200 yds.
    My shooting buddy gets pissed when I shoot tighter groups than him,with my little setup. LOL
    He shoots 20″ stainless with a Night force scope..pricey setup. Rem 77gr. SMK’s are killer in this gun. Almost does not seem fair ! The fun is back! I can not imagine shooting any other type of barrel. When they restock, don’t wait, buy one!
    Best AR investment I’ve made.

    I couldn’t agree more with Mark G on the previous review. This barrel had everything I was looking for and with superb accuracy. With that being said, you do have to be a capable shooter with a 16″ barrel to get good groups with decent ammo. I’ve personally shot a sub 1″ group at 100yds with PPU 69 gr. match ammo. Also a tight group with American Eagle 50 gr. Varmint ammo. The barrel can do it all. I’ve hit steel out to 600 yds with this barrel so far, repeatedly. Even a newbie friend shooting my gun for the first time was able to do it. I love this barrel, we need more like this !! Thanks to everyone at for getting these in stock. This barrel is awesome !
