Notes:

Incompatibilities:
- Geissele's Maritime Bolt Catch. Material from either the top edge of EMR-A's lever, or the bottom edge of Maritime Bolt Catch's lower paddle may need to be removed for both to work together. The close proximity of these two control surfaces makes this combination less than ideal.
- CMC's anti walk pins
- KNS Gen 2 anti-rotation trigger/hammer pins. KNS Gen2 Mod2 and Gen JJ, and Gen ST (Spikes Tactical) are compatible with EMR-A with standard lever, but not with extended lever. Gen2 Mod2's pins connecting bar may require minor fitting on thicker receivers to create adequate clearance for the EMR-A's lever when pressed.
- Battery assist device levers.
- Receivers with the left side fence around the bolt catch and mag catch, such as some CMT, Magpul and AR15.com billet receivers. EMR-A requires the left side of the receiver to more or less adhere to TDP spcs.
- HK 7.62mm AR style rifles, MR762 series.
- Hodge Defense Mod 2 lower receivers.
- May not be compatible with Seekins SP223 and AR10 B receivers.
- Due to lack of standards for 308 ARs, EMR-A may not work with 80% 308 ARs.
