Mk12 Mod 1 Military Correct Deployment Kit — Limited Edition | The Complete SPR Package from CCC
This is not a parts list — it is the complete Mk12 Mod 1 Special Purpose Rifle as it would have deployed, assembled and verified by Charlie's Custom Clones. The Mk12 Mod 1 was the evolution of the Navy's SPR program, developed by Naval Surface Warfare Center Crane Division as a precision engagement tool for SEAL and MARSOC operators who needed sub-MOA accuracy from an M16-pattern rifle. CCC's deployment kit includes every component required to put a military-correct Mk12 Mod 1 into service.
What Makes the Mod 1 Different from the Mod 0
The Mk12 Mod 0 used A.R.M.S. #22 rings, a PRI free-float tube, and the Leupold Mark 4 TS30-A2. The Mod 1 moved to the KAC URX (Upper Receiver Extension) rail system and the Nightforce NXS 2.5-10x24 — a scope purpose-built for the SPR program. The Mod 1 rail provided a full-length free-float handguard with continuous Picatinny rails at the 12 and 6 o'clock positions, and the Nightforce glass gave operators a more capable reticle and wider magnification range than the Leupold. Both variants use the 18" Douglas or Krieger HBAR barrel in 5.56 NATO with 1:7 twist.
What Is Included
CCC's Mk12 Mod 1 Deployment Kit is built from contract-correct and mil-spec components. The specific contents are detailed in the product specifications above, but every kit includes the complete upper receiver group, lower receiver group, optic, mount, bipod, suppressor (NFA item), and deployment case. Each rifle is assembled and inspected at CCC before shipping. This is a limited-edition offering — when current component allocations are exhausted, availability cannot be guaranteed.
What You Should Know Before Purchasing
This deployment kit includes a suppressor, which is a National Firearms Act item requiring a Form 4 transfer and registration with the ATF. As of January 1, 2026, the $200 NFA tax stamp fee has been eliminated — the paperwork process remains. The rifle itself ships as a firearm and requires FFL transfer. See ATF for current requirements. Contact CCC for estimated lead times on current production kits.

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.
