The boys from Milcomp visited us in order to test the APC556 PDW. Here is their review:
Laser-Ammo Adapter Kit cal. .45ACP
Use this adapter ring to convert your 9mm SureStrike into a .45 ACP laser cartridge. Simply thread the .45 Caliber Adapter ring onto the SureStrikeTM 9mm cartridge. Install the pipe with the nut, and you are good to go! This adapter allows you to expand your 9mm Kit so you can train with your favorite .45 caliber pistol.
No tools needed.
Important: All semi auto pistol adapter rings require the use of a safety pipe and nut.
