.45 Cal – Micro Comp – .578 X 28


.45 Cal Tactical Micro Comp For Barrels – .578 X 28 Right-Hand Threads

Made from aircraft-grade billeted 7075 grade III hard-anodized aluminum

If you have a 578 X 28 threaded pistol barrel then the .45 cal micro comp will work perfectly. With the addition of the micro comp, this adds a little over .5″ of an inch to the overall length. However, this comp will diminish recoil to nearly nothing and reduce most of the muzzle climb. This is the most effective pistol comp ever made for the HK series of firearms. The HK comp will keep your gun shooting flat and followup shots faster than ever before. This comp was designed specifically for the HK .45 cal series of firearms but will work with many other firearm applications if the barrel is threaded 578 X 28 threaded barrels.

  • HK45, HK45 Tactical
  • HK USP .45 Tactical, USP Tactical
  • HK USPC Tactical, HK USCP Tactical
  • Many other pistol caliber barrels in .578 X 28 such as Glock, Sig, etc.

2. screw micro comp onto barrel all the way until fully screwed on and/or stops

4. Make sure the comp is timed with the 3 oval sized ports at 12 o’clock
5. Add a drop of blue Loctite to the threads of each set screw (red Loctite or rockset are even better)
