The suppressor wrench is another Delta P Design product to support our customers. A nice wrench the “right size” for muzzle accessories with the standard 19mm NATO muzzle accessory flats: like the BREVIS line of suppressors. The standard AR15 A2 flash hider is a 19mm accessory. You can use it on ¾” accessories and we won’t tell anyone.
With that in mind, we decided to throw some of the answers into a compilation using some visual aids.
- What is it made of?
The wrench is made of hardened tool steel. This gives the wrench the proper rigidity and strength given the job asked of it.
- What do you mean by “radius jaws”?
The jaws of the wrench that actually contact the wrench flats on the accessory are not parallel flats, but radii. Radius geometry on the wrench jaws minimize the chance of marring the corners of accessory wrench flat corners. The geometry of the illustrations below are exaggerated for clarity. Note that the (yellow) radius wrench jaws contact the flats of the accessory whereas the flat wrench jaws (red) make contact on the corners of the accessory.

- Why is it thin?
The wrench is thin to fit into tight applications where the barrel or gas block of a suppressor application interferes with a typical wrench. It also makes it light and handy to carry.
- Why does it have a square hole in one end?
The hole in the wrench opposite the open accepts a 3/8” torque drive. It is preferred to mount the suppressor (or other muzzle accessory) with a known torque. Many online torque wrench calculators are available. Here are a couple on-line torque calculators:
The distance from the center of the 3/8’ square drive to the 19mm open jaw end of the Delta P Design suppressor wrench is 4.0” ( 102mm). 15-17 ft.*lbf. (20-23 Nm) has shown to be optimal for mounting the BREVIS line of suppressors.
- What is the coating?
The wrench is coated in the same ArmaGard oxide conversion coating as the BREVIS line of suppressors and is laser marked with the Delta P Design logo.
