The Daniel Defense M4A1 Block 2 is Daniel Defense's commercial interpretation of the SOPMOD Block II M4A1 fielded by US Special Operations Command since 2005 — the same RIS II rail program that DD originally built for the SEAL Teams and US Army. This FDE-railed rifle is built around a 14.5" cold hammer forged M4-profile barrel with a permanently attached DD flash suppressor (pinned and welded to 16.1" legal length), a DD low-profile gas block in a carbine-length direct-impingement system, and an M16-profile, MP-tested, chrome-lined bolt carrier group with a properly staked gas key.
DD gives you the clone-correct Block II profile where it matters — the RIS II FDE handguard and the overall package — while modernizing the rifle with the ambi GRIP-N-RIP charging handle, DD-logoed mil-spec 7075-T6 upper and lower, H buffer, and DD buttstock and pistol grip in soft-touch overmolded polymer. Rail panels are heat-resistant Santoprene. Caliber 5.56 NATO, 1:7 twist, government profile, 1/2-28 muzzle thread, carbine gas. Weight 6.74 lbs, overall length 34-3/4". Ships in a DD full-latch impact case. Manufacturer P/N 02-088-06027-011. If you want the 100% original USGI M4A1 Block 2 instead, ask our sales team. Otherwise, order this Daniel Defense factory build from Charlie's today.

This item must ship to an FFL holder. No civilian exceptions. Check your state laws, send us a copy of your FFL, and allow 3-4 business days for compliance review. California residents, click here. Free shipping does not apply to full rifles unless purchased with a scope.
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.
