We are liquidating these in preparation for a new barrel. Once this batch is gone, they’re gone forever!

*Adding a pinned low pro gas block gives the shooter the ultimate in worry free operation. Should the gas block screws work themselves loose during heavy use, the pinned gas block will keep you in the fight indefinitely. Adding this option here saves BIG.

This is our 16 inch Mid Length Gas, SOCOM/Medium 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 2lb 2oz and has 1:8 twist rate with 5R rifling. Extensions are left untreated to show that the Melonite was done correctly.

    I wasn’t sure what to expect from this barrel for the price, but was more than pleasantly surprised. The fit and finish was excellent, and it shoots great. I bought this for a budget build, but after using it I feel like I should have bought higher quality parts for the rest of this rifle because this is anything but a budget barrel. I will definitely look to Integrity for my next build, you can’t beat this barrel for the price!

    Shipping was lightning fast, like the fastest I’ve ever seen. Ordered on a Friday afternoon, received the following Monday. Barrel fits very snugly in upper receiver. Looks very nice overall. Some very, very slight scratches in the finish on the outside, near the muzzle end of the barrel, but no big deal as I’m sure I’ll scratch it myself once I start using the rifle.

    Justin got the barrel to me unbelievably quick. Seems like I ordered one night and got it out of the mail box the day after! It is a very nice looking barrel. If it shoots half as good as the lightweight version of this barrel that I have, it is a great buy! I expect to be really pleased once I get the new upper built!

    Finish is excellent. Fitment was perfect and installed with ease.

    First shots out of it was a five shot group using Hornady 75gr Steel match I had left over. The group was right at 1 inch. No break in procedure was done before this. If this is a sign of things to come, I’m very impressed and excited to see what it can do.

    Only wish it was dimpled for a gas block, but that’s not enough to take away a star.

    Very happy with the accuracy!! Nice finish too! I also wish one barrel was dimpled for a low profile gas block set screws

    Excellent barrel. Put this on my Daytona tactical ar. Went from 4″ groups to 1.5″ at 100yrds. 2.5″groups at 200 yds. I would definitely buy another. I was out shooting 4 other guys with$1500 ars, Rock River arms and colts. And they had$1300 Scopes. Mine is a$150 Nikon p223. So happy. Thanks allot!
