The PRO is a replacement for the CompM2, which has been discontinued by the manufacturer. The PRO has pretty much an identical look of the CompM2, with some improved optics and battery life, without some of the deep water submergibility that is not needed, unless you are a Navy Seal.
Charlie's Custom Clones has taken the iconic Wilcox mount, used in the original Mk18 and M4A1 rifles during the global war on terror, and has recreated the CompM2 optic, also known as the M68, but using the more modern Aimpoint PRO -- which has the same body shape as the CompM2 -- and replaced the new PRO knobs with the "new old stock" round caps and a three-way rubber band, in a period-correct look of the CompM2. I dare you: You will not know it is a PRO until you look under the right side to see the Aimpoint name and PRO and serial number. Otherwise, it is identical to the CompM2, but modernized.
All factory direct from Wilcox and from Aimpoint. Don't let "clone" in Charlie's Custom Clones make you think this is a fake. This arrives in the Aimpoint Pro factory box, and CCC has removed the modern caps and replaced them with Aimpoint factory replacement caps and rubber band, mounted the Wilcox, and boxed it all back up. The Aimpoint warranty for the PRO applies.
Aimpoint Patrol Rifle Optic is designed with input from a distinguished group of current and former professionals, the Patrol Rifle Optic incorporates many never before seen features to maximize this sight's performance within the challenging conditions faced by modern law enforcement.
The Aimpoint® PRO sight comes in a ready-to-go kit at a budget friendly price, a concept that appeals strongly to Law Enforcement units.
NOTE: The Aimpoint PRO mount has been replaced by the Wilcox mount and will not be included in the box. Similarly, the battery cap and adjustment dust covers that came with the PRO have been replaced with the period correct parts and will not be included in the box.
The PRO sight contains a Wilcox mount. It is also equipped with flip covers, a black front flip cover and a transparent rear flip cover that allows the user to engage a target with both lens covers closed in an emergency situation.
Accessories and mounts are available if you want to upgrade your PRO sight.
Please note that the appearance of some components of this product such as the rubber strap, the covers for the adjustment screws and the battery lid have recently changed.
The Wilcox mount is hard to find. This is new, military contract, direct from the manufacturer, and is "clone-correct" for the Aimpoint CompM2 / M68.
