Actually makes the AUG pleasant to shoot suppressed. The factory barrel, even with the suppressor gas plug, simply vents too loudly too close to the ear for comfort. It also doesn’t help overgassing much at all. My Heresy Design barrel is gassed perfectly on the low backpressure suppressor setting with my CAT ODB, and the high bp setting runs great with my OCL Polonium K. Minimal gas on both, and they sound great.

Im very pleased with this barrel. I used Bonefrog 77 gr Barnes match burner bullets with a primary arms raptor 1-8 LPVO and was able to shoot multiple 1 inch groups at 100 yards with this barrel. Extremely accurate. I was hitting man sized steel plates at 500 yards with this barrel and ammo combination. This barrel is extremely accurate with the right ammunition. I would highly recommend this barrel, a must buy for AUG enthusiasts.
