The MR556 A4 short-stroke gas piston operating system does not impart hot carbon fouling back into the action, allowing the weapon to run longer, with less maintenance and with less wear on internal components. Its adjustable gas regulator allows the operator to tune the action specifically for suppressed or unsuppressed operation. Fully ambidextrous controls, lighter weight and a slimmer profile make the new A4 easier to operate, manipulate and employ.

This is a firearm. It requires an FFL transfer before you can take possession. Pick it up in person at our store (4755 US-280, Birmingham, AL 35242), or have it shipped to the FFL of your choice anywhere in the country.
A completed ATF Form 4473 and a NICS background check are required at pickup, per federal law. A valid Alabama concealed carry permit (regular or lifetime) can serve as an ATF-recognized alternative to the NICS check.
