Has anyone used these and does anyone know what the difference is. The gus sailing them said there was no shortage of these. not sure if we're talking about thesame thing - i've seen CCI primers packaged in a plain white carton marked as military spec for (I believe) the M16. my understanding is that they had a harder cup specifically to prevent against slam fires in ar rifles (or any rifle with a floating pin for that matter). Can't recall if they were marketed as 5.56 primers or the packaging referenced the M16 actually. My $.02... Jared Link to comment Share on other sites More sharing options...

A63111 Posted January 17, 2010 Share Posted January 17, 2010 If they are the White Box CCI #41 5.56MM MILITARY PRIMERS , yes I have used them with no ill effects. The gun shop where i bought them stated that they were specifically made for the 5.56 with a hard cup to prevent slamfires. Loaded and shot several hundred without problem.

Jared They are marked 5.56 primers CCI #41 on the boxes I have, and yes they are harder than regular CCI primers. They functioned just fine for me in a CMMG M4.

saibot Posted January 17, 2010 Share Posted January 17, 2010 I use these exclusively for my .223/5.56 handloads for my AR. They always go bang. I had a hard time finding them where I live and I paid too much when I had the chance. Link to comment Share on other sites More sharing options...
