Ares Armor “EFFIN-A” 5.56mm Compensator
Ares Armor has developed a tunable compensator for 5.56mm weapons with 1/2-28 muzzle threads, which they are calling the “EFFIN-A.”
Jesse of Predator Intel describes the device:
This is the first Compensator that can be both stacked and tuned to
custom fit each rifle and the its gas dispersal. The EFFIN-A features
4 rows and 7 columns and 4 rows of ports that can be either opened or
closed off with of set screws. Threading is cut short eliminate the
possibility of a screw entering the chamber. This also bottoms out the
screw making sure you have a tight fit and withstand the pressure of
the gas forcing it out. You can also stack the Compensator allowing
for other options.This Compensator combats muzzle climb in two ways; The EFFIN-A
Compensator’s timed and tunable exit ports act as an outside force
that returns the weapon to a “position of rest” by directly countering
the force of the round being fired in relation to the standard
shooter’s contact points on the weapon. This Compensator is also
designed to directly increase the weapons moment of inertia by
accurately counter balancing the mass of the front of the weapon in
relation to the force of motion created by the original force.Due to the amount of time and money we spent on researching the amount
of pressure released during the act of firing a round and adjusting
the Compensator’s balance to correspond to it we will not be releasing
the exact weight until after the pre-order is finished and products
have already shipped. Note: testing was conducting with two types of
ammunition, Matchgrade and GreenTips. The general weight is between 4
and 5 ounces.The Compensator has an outer diameter of 1″ and is 1.95″ inches in
length when the cap is removed. You have the choice of selecting the
EFFIN-A Compensator in Black or Stainless Steel depending on which
aesthetic appeals to you or best matches your weapon.WARNING If you attempt to modify or use these devices in any way
attempting to create baffles for a suppressor, it will instantly void
our warranty and possibly land you in jail. PLEASE OBEY THE LAW!We do not recommend stacking more than two of these on top of each
other. If you do so, you do it at your own risk and it will also void
the warranty.
A promo video showing various people using AR-15s equipped with the device has been released; this is the “clean” version, which has loud music playing in order to block out profanity.
Although threads are not shown in the 3D rendering below, the cap is screwed on with the same 1/2-28 threads. It is thus possible to attach another EFFIN-A Comp to the front of the device. This exploded view shows how the device is “tunable.”
Tunable compensators have been made before, but I do not believe that I have ever seen a compensator threaded to accept another compensator (or other muzzle device).
The “EFFIN-A” is available for pre-order at PredatorArmament.com, with a projected availability date of September 1st. It is available in black and stainless. The pre-order price is $90.99.
For the price, I may just buy one for experimentation. $90 is definitely affordable in the land of 5.56mm comps. What I really want, thought, is a 51T Battle Comp.
“here in the Land of Uk “effin” is an expletive; a (more) polite way of saying “f***ing”” @ Tony – It means the same here in the US, too. However, F-in A is a meme where the A either means Awesome, or occaisonally Affirmative.
The comp is an interesting design, and probably one of the more tunable designs around. I’m always a little mystified, though, about how anyone makes an intelligent choice for a comp/brake. There are so many designs on the market that purchasing and analyzing all of them would be very expensive and time consuming. I guess this is a great example of ‘satisficing’.
Thanks to The Firearm Blog for mentioning our latest product from Ares Armor. We also appreciate all the comments. The 360 Degree ports allow you to put the screws only where needed to custom counteract the force in the area experiencing muzzle flip on your rifle. Stacking gives you additional customization as needed.
We are excited to get this product to our customers so they can see the effect first hand.
Kilroy – to adjust the compensator you shoot a mag as quickly as you can with all the ports either opened or closed. You see which direction the recoil pushes you, then you adjust the ports accordingly. Stacking will lengthen out the gas system and increase the objects moment of inertia. Useful for shorter rifles or if you wanted to add other capabilities such as flash hiding or window breakers.
I don’t understand tunable compensators. Do different guns need different comp patterns? I thought they all pushed up… Besides, even if t is possible to tune a compensator to particular rifles gas pattern, how is Joe shmoe supposed to tune something he literally can’t see? Just guess? We can’t all afford ultra high speed cameras to show us our comp performance.
Matt, not just each guns, but each load. Competition shooters often tune their guns that they can easily double or triple tab.
In full auto it is amazing. (video)
Looks like a lot of cleaning to me…
So basically, “Hey guys, you can totally turn this into a suppressor but don’t do it okay” *winkwink*
Nice to see the pricing isn’t “EFF-EWE.”
Seems incredibly gimmicky, and my BS flag goes halfway up reading this. First impression would be that this is a cool, but useless toy to put on your rifle. (Like half the stuff on people’s rails, right?) How exactly are you going to adjust the compensator? Why have all the holes tapped, isn’t it useless with all of them blocked? Maybe thread a couple so there’s a balance between more or less compensation? Why is it able to accept another comp? Will one not work well enough in some applications? I’m so confused…
ordered…waiting…
Looks COOL !
I have to say that the name made me smile: here in the Land of Uk “effin” is an expletive; a (more) polite way of saying “f***ing”, as in “pass me that effin wrench, will ya?”
The mere sight of this made me think, “Effin-A!”
If I may channel an internet meme: Yo dawg! I heard you liked compensators, so I put a compensator on your compensator!
For guns in 5.56 I think that using the $90 to buy ammo and range time and practicing will do more to help you deal with and manage recoil than a fancy compensator will.
I read the name of this compensator as “F/A.” Need to put down the janes.
