The LMT Estonian Reference Rifle is the civilian-legal expression of the R20 small arms system fielded by the Estonian Defence Forces — an LMT contract win against the most demanding NATO evaluation protocols in recent memory. This is the real rifle, built on the same MRP (Monolithic Rail Platform) upper and MARS-L ambidextrous lower that shipped to Estonia, with a 14.3" cold hammer-forged 5.56 NATO barrel pinned and welded to a compliant overall length.
The MRP upper is CNC-machined from a single forged aluminum billet — receiver and rail in one continuous structure — to eliminate barrel-to-upper tolerance stack and deliver the accuracy floor that NATO evaluators were chasing. The M-LOK forend, short-stroke piston operating system, and quick-change barrel interface mean this rifle is serviceable, upgradeable, and mission-configurable at the armorer level.
The MARS-L lower gives you fully ambidextrous bolt catch, bolt release, magazine release, and selector — not a kit, not an aftermarket swap, but factory ambi from the ground up. This is the rifle Estonia chose after testing every major contender in Europe and North America.
Limited production, NATO-accepted, and available to American shooters. Order yours today.
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.
