2. Issue: TACOM has become aware of units ordering 30 rd. commercial (i.e. polymer, etc.) magazines for their M4/M16 family of weapons. The M4/M16 Army authorized magazines are the following: NSN 1005-00-561-7200 (improved magazine) and NSN 1005-00-921-5004 (older magazine; use until exhaustion).
3. User Actions: TM 9-1005-319-10, the Additional Authorized List (AAL), states that NSN 1005-00-921-5004 is authorized, as well as NSN 1005-00-561-7200. Units may use the older magazine NSN 1005-00-921-5004 with the green follower until exhausted. The improved magazine is available in stock, NSN 1005-00-561-7200, and has a tan follower. The improved magazine features an improved follower and follower spring. These new features help to reduce the risk of magazine-related stoppages. Units are only authorized to use the Army authorized magazines listed in the technical manuals. Remember; “tan-is the plan, green-start to lean, black-take it back.” Magazines with the black follower are the oldest and should be turned in to your unit supply sergeant or local supply point.
4. Unit Commanders, contact your local TACOM LCMC Logistics Assistance Representative (LAR) or your State Surface Maintenance Manager upon receipt of this message for assistance. For assistance in locating your TACOM LCMC LAR, see below.
So there is the message. Once again, right hand has no idea what left hand is doing. In at least one case (Magpul PMAG) these so-called ‘commercial’ magazines have NSNs. This means they can be ordered right through the standard stock system. It’s amazing that TACOM has so much free time to write messages about issues that don’t exist. Naturally, you can still use the older magazine that had to be replaced by the development of an improved model, but you can’t use a ‘commecial’ magazine with an NSN. Classic.
