I have been running the Precision Armament AFAB on most of my rifles. It is may favorite muzzle device as it is the perfect combination of flash suppression, blast, and ability to keep the muzzle level. I have tested it again several other hybrid devices, and prefer the AFAB. The EFAB is very similar out of a 16" barrel, and not worth the extra size and weight IMO. The MAMs is more effective at recoil reduction, however has more blast as a tradeoff.
However I recently ordered a surefire suppressor, and needed a surefire adaptor for it. The warcomp seemed like it would fit my needs perfectly. 
The two rifles used in the test are very close. One is a factory SR-15e3 mod 1. The other rifle uses the same mod 1 barrel and gas system, however it uses a JP FMOS carrier and JP polished spring. Prior to today's test, they both had AFABs and performed similarly. The thing I focused most on was the deflection of the red dot after firing from the standing position. In this sense, the two rifles deflected about the same amount directly to the right. I did not notice any rise whatsoever with either rifle when both running the AFAB. The rifle using the JP components cycled slightly smoother than factory KAC. Not surprising since the JP carrier moves much more smoothly in the upper and the spring is slightly heavier. Today, I swapped the AFAB in the factory KAC for the Warcomp and took it to the range. As before, I primarily looked for the amount of deflection after the shot. I usually measure blast by having another shooter fire while I stand behind and beside them, however I was alone today, and did not conduct that test. Ammo used was wolf gold. The AFAB equipped rifle deflected directly to the right, I would estimate slightly less than 2 feet of deflection at my 50 yard target. The Warcomp equipped rifle deflected upwards, with minimal right side deflection. I would estimate about 2.5 feet up and 6-8 inches to the right. The warcomp definitely did not keep the muzzle as flat as the AFAB, but total defection wasn't too far off. I felt as though I could get a follow up shot about as quickly with it if doing somewhat aimed shots (example: headshot at 50 yards). If I were doing double taps as quickly as I could fire, I would be more comfortable with the AFAB. If I were to choose these muzzle devices purely on their individual performance on this test, I think it would still be the AFAB. I have not tested blast or flash suppression against each other, but from previous tests, I found the AFAB acceptable in those catagories. However since I will be using a suppressor, the Warcomp is a no-brainer since it's performance is not too far off the AFAB, and it allows me to use the surefire suppressor. 
I will note that the AFAB pictured has seen upwards of 10k rounds and it's finish is holding up like it's new. I haven't taken it off the rifle, but I'm imagine there is some erosion inside. To put this test in perspective: I was seeing 2-2.5 feet of deflection with the KAC rifles and these muzzle devices. I also shot a friend's RRA 16" rifle with carbine gas and A2. It actually weighed noticeably more than my rifles, however deflected significantly more. I'd say closer to 10-12 feet after firing. |

Nice review, thx! I was so surprised at the AFAB's performance after trying several other muzzle devices that all my AR's (and the wife's & son's) now have AFAB's. Tomac Yep, I have several myself. The one in this test is staying since it just seems to work so well with that rifle. I'm going to swap warcomps in others though so I can use the suppressor. FWIW, the AFAB used in this test was the original AFAB-mini, not the current AFAB-5.56. |

I spoke to PA about it a few months back, and they said it was mostly an upgrade to the flash suppression. The truth about guns did a test, and the two did not differ significantly in recoil testing. |
