After the understandable backorder, I finally got my 5 Cprod 6.8 mags today. They look great, Larry. Now, I'll have to get the barrel. I've tried to educate myself on the 6.8 lately, and I've read where the "high prophets" have recommended 1/11 twist, 4 groove rifling, to handle the hotter "combat" loads such as Silver State Armory is offering. I want to order from Denny's, but he doesn't state the rifling grooves. The twist is right, and he told me on the phone they have the "improved" chamber which I hear is important for this newish caliber. What are your thoughts on this, Larry? I want to pre-Osama this barrel. I think the caliber is getting a "trial" in Iraq. I'd like to know the bbl specs there and if they're using the SSA loads. Does anyone know the specs? It's hard for me to reach Denny during the day from work. BTW, Larry, is there any ETA on the replenishment on SS AR 30rd mags? Jon
