Angel Custom, don't compromise for second best!

Angel custom barrels are designed by the most advanced Airsoft players in Hong Kong, USA and Japan providing you the maximum quality, durability, grouping, range and accuracy you seek for your rifle. A 6.01mm stainless steel tight bore barrel is essential to maximize the performance and accuracy of your AEG rifles. Stay ahead of the competition and upgrade your rifle to it's full potential. What is the difference between these barrels and others? (A: They are made out of steel and they are 6.01mm). What is the difference between these and Prometheus barrels? (A: They are 6.01mm instead of 6.02 providing even more accuracy and range without the yen exchange rate added to the price tag.)

Most manufactures choose not to manufacture stainless steel barrels due to it's high cost and manufacturing complexity, however, steel barrels are by far the best AEG tight bore inner barrels due to the nature of steel being rust free and hard. Copper or aluminum, are commonly found in most stock or leading brand tight bore barrels, but they will eventually deform from bb impacts through out time. The bore, 6.01mm, is also the tightest barrel diameter one should ever use on an AEG for maximum accuracy, range and grouping. Being a 6.01mm tight bore steel inner barrel, the Angel Custom tight bore barrel provides you all the features you would seek in a Prometheus barrel, or simply a tight bore barrel and more.

Review by Airsoft Retreat - Booligan

Introduction:
Angel Customs is a manufacturer of high quality internal and external parts, and today I'm going to be reviewing one of their stainless steel tightbore inner barrels. Angel manufactures these barrels in a variety of lengths, from 110mm MP5K length all the way to 650mm PSG1+, with pretty much every AEG in between covered. I will discuss all of the various pros and cons of these barrels in this review!
They can be found HERE
Ordering: I was sent this barrel by Evike.com, who has recently started carrying pretty much all of Angel's products. The various barrels are priced between $32 and $53, depending on length. This model, the 510mm length unit, is priced at $50. The rest of the barrels can be found on Evike.com. From what I can see, they only have AEG cut barrels currently, but they are producing several bolt action parts, so I wouldn't be surprised if they started selling VSR cut barrels soon. Evike packaged the barrel well for shipping inside a cylindrical tube package with bubble wrap inside, keeping it safe during transit.

Basic Information:
Angel Customs manufactured this barrel out of stainless steel, both for strength and durability. It is listed as having a 6.01mm inner bore, which is much tighter than most stock inner barrels, as well as many aftermarket inner barrels. As mentioned before, you can get these in pretty much any length that you might need for your AEG.

First impressions/Packaging:
Angel Customs packages their inner barrels inside a clear plastic tube, like most inner barrel manufacturers. At the ends of the barrel, they've inserted small rubber plugs, to protect the muzzle and hop-up openings from damage during shipping. This is a small touch, but it shows that they care enough about their product to keep it safe. There are two stickers on the tube, one indicating that it is made by Angel Customs, and one indicating the length.

Inner Barrel Details:
There's really not too much to say about the barrel that hasn't already been said in this review, however, I will stress the fact that it is made out of stainless steel, which is one of the preferred materials to make inner barrels out of. To help you keep track of the length and bore of your barrel, Angel laser engraved the barrel with that information.

At the hop-up end, you'll notice that it has two notches for locking in the hop-up. The hop-up window is cut at an angle, which can help prevent damage to the bucking by reducing the sharp edges for it to contact.

At the muzzle end of the barrel, you'll find that it has deep crowning, which helps prevent accuracy issues when firing. It does this by providing a smooth path for excess compressed air to escape around the BB at the moment it exits the barrel. This effect is more pronounced on real firearms, of course, but in theory, it works for airsoft too.

Muzzle crowning:
The inner bore of the barrel is very highly polished, and is without any defects that I can see. It is an extremely smooth bore, and a BB slides smoothly down it. When you place a BB in the barrel, cover the muzzle with your finger, it takes a very long time for the BB to slide down the barrel, indicating that the barrel has a very tight bore.

Performance: The barrel may be pretty, and it is made of great materials, but that's not any good if it doesn't increase the performance of your gun. Luckily, that is not the case with this barrel, as I saw a noticeable increase in FPS and range, as well as a decrease in grouping size. For testing purposes, I installed the barrel in my Javelin M4 based custom rifle.

Since the review, I had installed the M16 length outer barrel, as well as a Javelin 500mm inner barrel, that I took from my Javelin AK project gun. After swapping in the longer inner barrel, I saw an increase in FPS from about 376 to 380 consistently. This gave me a decent starting place for testing the new barrel.
Before installing the barrel, I cleaned it with a cleaning rod and patch to remove any excess oils from the manufacturing process, and was pleased to see that the patches came out quite clean. Installing the barrel was a piece of cake, as it fit perfectly inside the hop-up unit and the outer barrel. The length was perfect for my M16 length outer barrel, and went right up to the end of the muzzle threading, leaving no wasted outer barrel length. After installation, I shot two hi-caps through the gun with Matrix .20g BBs, to break in the barrel, and remove any tiny burrs that might have existed. I did a quick chrono test before breaking in and afterward, and saw no difference in the results, so it doesn't appear that this barrel will require any break-in before use.

Chrono results, using Matrix .20g BBs came in between 402.6 and 404.2 FPS, an increase of 20 FPS on average over the same length, but stock bore inner barrel, and with increased consistency. This is to be expected with a tighter bore, as less air gets wasted bypassing the BB. Accuracy and range increased as well with this barrel. With the stock bore M16 length barrel, I was able to hit a torso sized target at 165' 90% of the time, and after installing the Angel barrel, I saw that range increase to 175', using .28g BBs. This increase in effective range can be attributed to the increase in velocity, however, there was a lot less side to side deviation in my shots compared to the stock bore barrel.

For more precise testing, I set up an 8x11 target outdoors at 90' in order to get grouping size before and after installation of the barrel. Firing from a prone rested position, and using Matrix .28g BBs, I was able to get the following groupings:



As you can see, the grouping tightened up substantially with the Angel barrel vs. the stock bore barrel. At short range, most of the deviation is from top to bottom, with side to side being quite tight. Grouping size with the Angel TBB was about 2.9?? with the stock barrel being closer to 5??

Overall, you can see that the performance was greatly increased across the board using the Angel 6.01mm tightbore barrel. I saw an increase in velocity, consistency, usable range, and precision. For the price, this thing gave me one of the best bumps in overall performance that I've seen.

Pros:
