The boys from Milcomp visited us in order to test the APC556 PDW. Here is their review:
Laser-Ammo Adapter Kit cal. 223
Convert the standard 9mm SureStrike™ into a 223 for use in your AR-15. Simply thread the 223 barrel adapter into the SureStrike laser install the 223 action cap, and you are good to go! No tools needed!
