CORE Defender 11.5" UIC Pistol

The 11.5" UIC Mod 2 Core Defender is Pistol built to be the perfect balance between mobility and utility. The CORE barrel profile is barrel designed with tactical shooters in mind. These barrels are built to address issues with weight distribution, balance, and handling of traditional profiles, while increasing performance through consistent harmonics and uniform heat dissipation. Built on a billet aluminum, fully ambidextrous upper and lower receiver set, the ADM UIC Pistol is the compact version of our Universal Improved Carbine line.

CORE vs Hybrid Profile Barrel Contour:
The CORE Barrel Profile is a continuous taper and is about 4 ounces lighter than the standard Hybrid Profile Barrels we offer. This barrel profile was designed to aid in balancing the rifle specifically when using lights, lasers and suppressors by keeping most of the weight on the chamber end of the barrel, at the mid-point of the rifle.

NOTE: ALL FIREARMS CURRENTLY HAVE A 10-12 WEEK LEAD TIME AFTER RECEIPT OF FFL. All firearms are Build To Order. The build process will begin when ADM has the order and a copy of the customer's FFL where the firearm will ship to. Orders will sit pending until the FFL is received. Please have your dealer email a copy of their FFL with the Customers Name and Order Number in the subject line to FFL@ADMMFG.COM.

NOTE: Due to UPS requirements, Pistols require special handling, insurance, and will incur shipping fees of +/- $150.00. 

While American Defense MFG tries to stay current on all state laws, it is the responsibility of the customer to ensure that the firearm they are purchasing is legal to ship, as presented on our website, to their dealer of choice, and that the dealer is willing to accept the transfer.

Great Pistol

I have been buying guns a long time, but this one is real special one. Very good well done, finishing perfect. Congratulations to American Defense. F.O

Love This Folder

This thing is rad! It's super accurate and in a compact package. Having the ability to fold it and put in a bag or backpack is awesome! The Law Tactical hinge is the way to go. I've tried other brands and these are built like a tank.
