A-hole Mk 4a Muzzle Brake from Arson Machine

Arson Machine’s new A-hole Mk 4a Muzzle Brake is a serious muzzle device with a not-so-serious name. As you can see from their previous teaser video, it’s very effective and while the name A-hole is funny, it’s also descriptive. This brake actually has ports shaped like the letter “A” and it’s loud so… it’s a break with A-holes and for A-holes.

The A-hole Mk 4a Muzzle Brake is machined from aluminum which weighs less (1.11 ounces) but will wear out far sooner than steel, about 1000-2000 rounds (maybe more). The cost reflects that. It comes with a shim kit and costs less than $30. For $90, less than the cost of most devices, you could have 3 of them along with 3 shim kits you can keep using.

As usual, the product description on Arson Machine’s website is full of laughs so don’t miss it. Check out the A-hole Mk 4a Muzzle Brake at Arson Machine.

Arson Machine – TP9SA Decock Block

The Canik TP9SA handgun is gaining a reputation as a solid value but many users are (understandably) wary of the two large decking buttons locating top of the slide, fearing that the gun could be decocked at an inopportune time. Arson Machine is now offering a bit of cheap insurance that ensures that your TP9SA will not be decocked accidentally. The Decock Block consists of two small spacers that can be installed under the Canik’s decocking buttons, completely preventing them from being pressed.

This modification will require you to pull the trigger to decock for field stripping/disassembly much like a Glock or other striker fired guns.

Arson Machine Co. Troy Light Mount

If you have a Troy Alpha rail (or similar), check this out. Arson Machine Co. is selling their Troy Light Mount at a reduced price. Due to some issues with their supplier, they don’t have any of the backing plates that would normally be packaged with this mount. The good news is that the mount works perfectly with the backing plate that Troy provides for the short rail that is included with each rail.

Arson Machine Co. has decided to forgo the inclusion of the backing plate and sell the mounts at a special price. Check out the Troy Light Mount at Arson Machine Co.

Arson Machine Light Mounts

Arson Machine makes light mounts right here in the USA, Oregon to be specific. Their line includes mounts for Keymod, M-LOK, MOE Hand Guard Slots, and even a mount specific to the Beretta CX4 carbine.


The mounts are machined from 6061 aluminum with hard anodized finish. They can accept a 1″ flashlight ring or a Scout adapter for Surefire’s M300/M600 series of weapon lights. The mounts are designed to keep the lights relatively close to the rail and offset them from the mounting point.

Check out Arson Machine and keep an eye on them for future releases.
