EMR-A v2,
Short is a shorter version of EMR-A v2. EMR-A v2 (2024 to present)
replaced the v1 EMR-A (2017 to 2024).
EMR-A v2
uses the familiar and superb Norgon Ambi-Catch mechanism where the entire mag
catch plate pivots when pressed on the left side, whereas EMR-A v1 used an
aluminum lever attached to the magazine release plate and when the lever is
pressed, the plate is lifted away from the receiver.
EMR-A v2,
Short bears striking resemblance to the Norgon Ambi-Catch since it uses the
Norgon mechanism. The short EMR-A v2 has the texture we designed for
EMR-A, i.e. 20% of the textured section is raised and forms a shelf to provide
additional purchase. EMR-A v2, Short has a small plate/lever, there isn't
much surface area to work with, this in turn makes a good texture more
important.
Two lever
options are available. Standard and short. For duty and defense
ARs, we recommend the short lever, as the plate sits inside the mag catch slot
and is lower in profile.
A 10.9lb
rated magazine catch spring is included with each EMR-A. We've long
considered the standard magazine catch spring to be rather weak (rated at
8.3lb), accidental / unintended mag drops can take place if a user slings his
weapon, and has gear and pouches on the vest. A stiffer mag catch spring
mitigates these risks, thus it is an integral part in the EMR-A package.
EMR-A v2 is
shipped with a 10.9 in lb spring. While EMR-A v2 doesn't use the main mag
catch since it has its own spring, the 10.9 in lb spring makes the right side
mag catch button stiffer and less prone to accidental magazine drops.
The LP (low
profile) mag catch shaft reduces the mag catch shaft length by a full
revolution, or 0.03. The LP option on the EMR-A reduces the installed
height of the right hand mag release button, resulting in a right side mag
release button that sits below the mag release fence. This is our latest
step to mitigate accidental / unintended mag drop risks.
The LP on
the EMR-A will not reduce the EMR-HC's installed height on an AR15/M16 to the
point where EMR-HC doesn't constitute accidental / unintended mag drop
risks. The LP option's shorter mag catch shaft aims to reduce the
installed height of a TDP spec mag release button (such as our EMR-H), it isn't
a solution for extended mag releases, the installed height of which would
require a drastically shorter shaft to offset.
