Talk:Beta C-Mag

Weight

It says that a fully loaded c-mag would weigh the same as three fully loaded 30-round mags. That doesn't make sense.

100 rounds weighs more 90 rounds of 5.56mm ammunition, I would assume they meant four.

Beta C-Mags are made of polymer, that might take the weight down a little, compared to regular steel mags.

Keep in mind that 'three fully loaded 30-round mags' are the weight of 90 rounds and the weight of three empty steel magazines. These three empty magazines may very well weigh more than 10 rounds and a bit more. So thus a 100 round C-Mag made of light polymer would weigh less than the heavy steel.

>>>Unless you are referring to the limited numbers of HK PI mags (which are steel), the mag bodies are aluminum, not steel.<<<

This page needs updating, the 1994 Clinton Ban (for lack of better terminology on my part) has long since passed.

Added as many sources as I could find. I couldn't find any info on GPM-02-0217 or the claims made in the tolerances section. Hopefully someone else will have better luck. Jirt 20:46, 18 March 2007 (UTC)

Variants

I think the article would benefit from a short section regarding the variants. That is different weapons systems (Mini-14, etc.) and calibers (9x19mm NATO, 7.62 NATO). Thoughts? Surv1v4l1st ^{(Talk|Contribs)} 20:09, 14 July 2009 (UTC)

All of the variants in a specific caliber use the same base. Only the feed towers are swapped. --D.E. Watters (talk) 01:20, 15 July 2009 (UTC)

Unsourced/unreferenced material

Moved content below from article. Tags re citations/references date back to late 2010, and link to GPM-02-017 is dead (only search results for it for were references to this article). --Cawpycat 23:54, 1 April 2012 (UTC)

Tolerances

The interchangeable feed clip (or "tower") on older Beta C-Mag editions have some problems in later AR-type weapons with closer tolerances for the magazine well. The old feed clip which inserts into the rifle's magazine well is encircled by "ribs" molded into the exterior of the upright tower. As a result, the magazine cannot be inserted into the magazine well far enough to fully seat.

Problems are exacerbated in dusty and sandy environments. The C-Mag also stresses the magazine release, since a fully loaded C-Mag weighs more than four fully loaded 30 round magazines. U.S. Army TACOM has issued a Ground Precautionary message, GPM-02-017, warning about its use in operations. The GPM predates the initiation of Operation Iraqi Freedom.

Additional weapons

Since the JS 9 mm, the Daewoo K7 and the VBR-Belgium PDW can use magazines from the MP5, Uzi and Glock respectively, then I guess they accept C-MAG magazine, don't they? Furthermore, can all the STANAG magazine weapons accept C-MAG magazines as well? --Ts7946 (talk) 12:00, 16 August 2014 (UTC)

Spacer Round?

The article mentions "spacer rounds" but I can't find anything about what these are. The diagram in the article looks interesting but nothing explaining what the different colours are, red? black? Hickster uk (talk) 22:08, 12 June 2024 (UTC)
