Ares Armor Effin-A Compensator 5.56 MKII
Effin-A Compensator MKII
is designed to allow users the ability to adjust the manner in which
the gas exits from the weapon. The Effin-A Compensator MKII features 8
columns and 3 rows of exit ports that can be either opened or closed
through the very simple use of set screws. The exit ports are not
threaded completely through to eliminate the possibility of the screw
being over turned into the chamber. This feature also allows the screw
to "bottom out" increasing tightness and ensuring that it will not work
itself out under the pressure of the gasses being released by the
weapon. The Effin-A Compensator MKII weighs in at only 2.5 ozs; which is half the weight of the previous version. Allen Key is included.

Additional Information on the Effin-A Compensator 5.56 MKII
Objects at rest tend to stay at rest and objects in motion tend to stay in motion unless acted upon by an outside force. Muzzle flip is caused by the pressure that is released down the center of the bore in relation to the contact points of the weapon and the shooter. Muzzle climb is solved by this device 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" after the round has been fired (the round acts as the initial force causing the unwanted motion) by directly countering the force in relation to the standard shooter 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. The balance concept is similar to ancient weight ratio techniques used in spears to allow steady aim and flight.
Note: testing was conducting with two types of ammunition, Matchgrade and GreenTips.
The Compensator has an outer diameter of 1" and is 1.95" inches in length when the cap is removed.
I grabbed an "effin-a" comp because I was really curious. I fired my new build for the first time tonight. I was more concentrating on weapon function but was doing a little comp tuning too. The difference between the wide open ports and tuned ports was crazy.
After shooting with it with all of the ports open, and seeing no difference, I started by sealing the bottom and leaving the top three rows wide open to compensate for rise. Holy mother, the rifle was slamming itself down, and considerably so. I was amazed at the difference the ports were making. That being said, I've never shot anything but A2 birdcages before tonight.
I made a few adjustments and it leveled off considerably, but I have more work to do. With some more fine tuning this thing will be rock solid.
This I will tell you, comps make a difference.
Keep this in mind... I've never seen flames from an A2 bircage muzzle device. EVER. In my well lit indoor range, I was seeing balls of fire with this effin-a. If hiding from your opfor at night is your goal, skip the effin-a.
