Daniel Defense
Daniel Defense PDW lower receiver with collapsible stock... BAM !!
The Daniel Defense PDW lower receiver with Maxim Defense CQB collapsible stock is built for one purpose: delivering familiar AR-15 handling in a package suited to vehicles, confined spaces, discreet transport, and close-protection work. When paired with a short-barreled upper, it creates a compact platform that is appreciably shorter than a conventional Mk18-style carbine while retaining a functional shoulder stock.
The foundation is a forged 7075-T6 aluminum Daniel Defense lower, paired with the shortened receiver extension and multi-position stock system of the Maxim Defense CQB. Fully collapsed, the stock substantially reduces overall length. Extended, it provides a usable cheek weld and shoulder contact without changing the familiar controls or operating characteristics of the AR platform.

Highlights
Forged 7075-T6 lower: High strength without unnecessary weight.
Type III hardcoat anodizing: Resists wear and corrosion.
Flared magazine well: Guides faster, more positive reloads.
Rear QD sling point: Supports compact sling configurations.
Integral trigger guard: Eliminates a separate guard and roll pin.
Mil-spec AR architecture: Accepts standard components and select ambidextrous controls.
Maxim CQB Gen 7 stock: Provides four positions in a compact footprint.
Maxim CQB buffer system: Includes one buffer and two spring weights for configuration-specific tuning.
Build it as a registered SBR with an 8-inch .300 BLK upper for a compact, suppressor-oriented package. A 10.3- or 11.5-inch 5.56 NATO upper creates a slightly longer configuration with familiar ammunition and carbine handling. In either caliber, buffer weight should be matched to the barrel length, gas system, ammunition, and intended suppressed or unsuppressed use.
Daniel Defense does not ordinarily sell complete lower receiver groups as standalone components, which makes this factory PDW lower especially difficult to replace. For the collector or builder planning a serious compact AR, it brings the receiver and specialized Maxim stock system together in one ready-to-build foundation. If a Daniel Defense PDW or short-barreled carbine is on your project list, this is the part around which to build it.

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.
