A couple of months ago, TFB’s own Miles V in the second part of his interview with George Huang, the founder of Battle Arms Development, has reported that among other new products the company was also developing barrels for Glock pistols. These new barrels are called BAD ONE:1. They have just hit the shelves and in this article, we’ll see what’s cool about these barrels.

I have to confess … when I first heard about the availability of these barrels, I was hesitating to write about it because “just another Glock barrel” sounds like a really boring subject. But after a little bit of research and chatting with the company officials, I discovered that these are not just rebranded barrels that were made by a large manufacturer. These new barrels are completely made by the Battle Arms Development with a rather interesting and unique technology that I am not aware of any other manufacturer doing it like that. Let’s first see how the company describes the process of making their barrels:

ONE:1 utilizes revolutionary machining process where one machine comprehensively machines every part of the barrel from the beginning to the end. The process includes the ultra-precise single point cut rifling where the rifling is done with almost a hundred minuscule cuts.

This method does not introduce stress to the barrel and no stress relieving is necessary after rifling. Perfect concentricity between chamber, bore and rifling. This process also yields uniform twist rate and ultra-accurate rifling grooves with deviation of less than .0001in from groove depth to groove depth.

Yes, it is exactly what the description says. They basically put a blank of steel into the CNC machine, let it do its magic and once they open the windows of the machine they have a completely finished product (less the coating) that is profiled, chambered, drilled and rifled. According to the company, this method of manufacturing allows them to avoid possible errors when transitioning the part between different machines. As a result, they get a very precisely machined product. Needless to say that the single point cut rifling also helps to have a match grade barrel. That method of cutting the rifling is arguably the most labor-intensive and time-consuming one resulting in the most accurate barrels possible.

Battle Arms Development ONE:1 barrels are designed for Glock 19 pistols of all generations. They are also compatible with Glock 19X pistols. These barrels have a twist rate of 1:10″, an 11° crown and straight fluted profile. They are available in threaded and non-threaded versions. The non-threaded one is made of 4140 steel with a QPQ black nitride finish. The threaded version of the ONE:1 barrel is made either from 4140 steel or from 416 stainless steel. The threaded barrels have a 1/2×28 thread pitch and come with a SABERTUBE dimpled thread protector and a rubber O-ring.

The MSRPs of these barrels are $199.95, $219 and $249.95 for the non-threaded 4140, threaded 4140 and threaded 416 stainless steel versions respectively.

    Beyond the external cosmetic machining, this is one of the better barrels on the market. They are machined to very tight tolerances and have excellent QC. Everyone complaining about the barrel has never used one. The equivalent of a POG complaining about his gear preforms in "combat".

    Now make one for a CZ 75. Oh wait, they don't need one.
