Knights Armament SR-15 CQB Mod 2 — 11.5" MLOK Carbine Upper

Knights Armament didn't build the SR-15 to be popular. They built it to win contracts — and they did. KAC holds the M110 Semi-Automatic Sniper System contract, supplying precision rifles to Army Special Forces and Ranger Regiment sniper teams. That victory was earned through decades of precision manufacturing, obsessive attention to bolt-to-barrel-extension lockup, and a documented reputation for delivering exactly what SOCOM specifies, on time, to standard. The SR-15 CQB Mod 2 brings that contract-grade engineering into an 11.5" close-quarters platform — KAC's answer to the CQB mission with no compromises.

The URX4 MLOK Rail: KAC's Latest Platform

The proprietary KAC URX4 MLOK rail represents KAC's most current rail system iteration — modular, lightweight, and built to the exacting tolerances that differentiate KAC products from the broader AR market. KAC does not license this rail to other manufacturers. If you want a URX4, you buy a KAC. The bolt carrier group is KAC's E3 design, refined through years of military deployment feedback. Every control is ambidextrous — built for professionals who may shoot under stress with either hand. This is a rifle built for people who do not accept functional compromises.

Why Genuine KAC Access Matters

KAC maintains tight distribution control. They are deliberate about who carries their product because they care about how it is represented and who ends up behind the rifle. Major volume retailers can order Colt and Daniel Defense products easily. Genuine KAC inventory is a different matter. Charlie's Custom Clones has maintained KAC product access since 2017 — a relationship built on our reputation for military-clone accuracy and our customer base of collectors and operators who take authenticity seriously. When KAC inventory is available through CCC, it is the real thing.

THIS IS A SERIALIZED FIREARM.  It must ship to a Federal Firearms License holder.  No civilian exceptions.

Buying and shipping through Charlie’s is easy, but there is some information you need to know. Only a federally licensed firearms dealer may receive a firearm or federally regulated serialized item (like a receiver or suppressor). We cannot ship these items directly to you. Please follow these steps to process your transaction:

1)     Check your state laws to make sure the federally regulated item you want to purchase is legal in your state. Your FFL dealer should be able to give you all of the necessary information regarding your state specific laws. But, if we ship to your FFL, and there is a legal issue, we cannot accept a return. So please make sure that you know and follow your local and state laws.

 

2)     A quick google search will show you what Federal Firearms Licensed (FFL) dealers are in your area. When you are ready to purchase, contact the FFL dealer you would like to use and get their shipping address. During the check-out, put YOUR address in the “billing” section and the FFL DEALER’S address in the “shipping” section. If you don’t know your FFLs address, that’s okay. You can send the information later.

 

3)     After check out, make sure to contact your FFL dealer to ensure they will receive your shipment for you (most do this for a small fee, but you should always double check).

 

4)     Have your dealer send us a copy of their FFL to FFL@CharliesCustomClones.com. Charlie’s does not reach to your FFL (MAKE THEM EARN THEIR FEE!!!)

 

5)     Be patient! In order to ensure we remain compliant with all federal laws, our compliance department is kept separate from our sales and operations team. Please allow a few days for our compliance officer to verify all of your dealer’s documents and ensure all federal laws are being observed. You should hear from our compliance department within 3-4 business days. If not, feel free to reach out for a status update.

 

That’s it! We try to make this process as simple as possible for our customers, but if you are unfamiliar the process or have any other questions, please visit our How to Buy a Firearm page for more details.

California and New York residents please, click here. The process may be different due to state specific laws.

NOTE: The free shipping option does not apply to full rifles, unless purchased with a riflescope.  If you choose free shipping at check-out, we will bill you for shipping later.
