16in ‘Vindicta’ Barrel – Integrity Arms Match 5R, Wylde (.223/5.56)

Rated 5.00 out of 5 based on 8 customer ratings

VINDICTA: Latin for Liberation. Also means vengeance or defense. One thing is sure, you’ll feel liberated once you shoot this barrel as you push yourself to the limits of your capability.

*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.

Sub-MOA guaranteed, these new barrels quite possibly bring the best of features and options for an extremely competitive price. The term ‘match grade’ is used rather loosely in the gun industry, but this barrel stands apart and will definitely impress even the best shooters. Pay attention to the options and you’ll see why this stands apart.

Melonite treated inside and out, locking in the bore and providing extreme durability. 

The Wylde Chamber was designed to be a match grade/more accurate chamber for the .223 cartridge, while still allowing safe operation with 5.56 NATO ammo

The barrel extension is NP3 coated for extreme lubricity even when dry. Dirt and residue won’t cling to the NP3 and will wipe off very easily.

The polished crown allows the bullet to leave uniformly and evenly, giving it a nearly perfect flight path

The 5R rifling reduces sharp angles, gives less bullet drag and deformation. Slightly faster velocity and ease of cleaning are also a benefit

Ordnance Grade 416R Stainless Steel (HRC 28/32) ensures seamless machining for a near perfect bore

Individual Magnetic Particle Inspections on each barrel assures zero defects in material or workmanship

Simply put, this barrel is feature packed at a price point that is very reasonable compared to other match grade barrels. Give one a try and we are sure you will be impressed, or return it for a no questions asked refund within 30 days. Our contract shop for these is ISO:9001 and AS:9100 certified as well a current DOD contractor with years of experience in several industries. Melonite is more durable than Chrome, and can be machined correctly since there is no added layer.

    Been a fan of integrity for a while. Decided to try this barrel and it is nothing short of awesome. Finish is flawless and I’ve never seen a crown polished so perfectly. After dialing her in I shot sub moa consistently with IMI 77gr razor core and SMK’s too. Can’t wait to find a load it likes and watch it sing.

    Liked the options and tried one. First impressions unboxing the barrel were excellent. The finish is even and a deep black with no blemishes, barrel markings are crisp. The crown is polished to a high sheen and is flawless. Gas port seems to be beast perfect as recoil is light and feeds 223 and 556 flawlessly. Accuracy is excellent. Sub moa easily. All in all this barrel rivals those of a much higher price tag. Shipping was super fast too.

    Pleasantly surprised at the quality. Unboxing and first glance were better than I expected. I’m somewhat ‘snobby’ about my gun parts not because I only use $2k AR’s, but because I get sick of fly by night companies passing off crap for quality. Deep black uniform finish, clean bore, HIGHLY polished crown, NP3 extension, MP tested,etc all make for an excellent barrel on the surface. Shooting this barrel verified it was both show as well as go. First group with Magtech 556 was 2″ at 100 yards off a bag. Put it in a sled and shot some black hills for sub MOA…second time out. No question this barrel will perform.

    I purchased two of these when they were intro pricing. WOW! I wish I had bought more. Excellent all around. I would put this barrel up against any barrel. It is beautiful and performs flawlessly. Sub moa and looks good doing it! Another great item purchased from a great company. Thanks Integrity!!

    No issues after about 3k rounds. Still holds moa pretty easily and I’m not a crack shot.

    Had an upper built with this barrel and an Aero M4 upper. Fit was very tight between the barrel and upper. Had to tap it in a bit with a mallet, but tighter is usually better. Not sure if it was the Np3 coating. After adjusting my scope (bushnell 1-4x) I was easily under an inch and a half at 100 yards first time out. I got serious and was able to pull out a group of under an inch with some IMI razor core. I know it could do even better.

    Great barrel, well worth the money. It shoots as well as advertised. Velocity has been great, it seems to like warm loads and seems very forgiving about pressure. 23.4gr of AR-Comp with NCC 69s, 23gr with 77s, have both been remarkably accurate. I would certainly purchase it again, and wish I had gotten one or two more when they were at the introductory price.

    Big fan of Integrity Arms products. I think this is my 4th barrel from them. Bought this barrel for a build I did for a friend. After dialing in the scope (4-12x Vortex Diamondback on a Midwest Industries QD mount) I shot 5 consecutive 3-shot groups with Hornady Vamint 55gr Vmax factory ammo. Distance was 100yd. Largest group was 5/8″ CTC, Smallest 1/2″ CTC for an average of 9/16″. Groups with 75 grain “match” ammo from Nosler and Hornady were in the 1″ range. Walmart Bulk 55gr was about 1.5″
