Best Source for 6.8 SPC magazines ?

I'll second that request, but add "6.8 SPC mags that don't rattle.

I use PRI exclusively. I think they are the best with Magpul no tilt followers.

PRI is great quality and allows the longest OAL if you handload.

ASC is rumored to be using the former CProd's equipment.

I just got a couple AR Stoner 5 rnd mags from Midway. Haven't used them yet but they look fine. Rumored to be made by ASC.

CProducts doesn't exist anymore, but their mags are still floating around and work well for me.

Barrett makes 30 rnd mags that are very solid but restrict to the shortest OAL.

Finally, D&H have said that they are developing their 6.8 mag, but the release date continues to be pushed back.

Sources: Midway, BravoCompany, direct from manufacturer, Cheaper Than Dirt, JoeBobOutfitters, etc.

Search for 6.8spc magazines on Bing, you get two pages of solid response. Not so much for Google, a hit based search engine won't do the same as a keyword relevant search. Different focus, and why you get radically different results.

You also find the smaller regional suppliers that aren't AR top of the page mainstream but still have good stocks, like Widener's, Palmetto, etc.

I check BCM daily, D&H said they won't release until they are good to go, and we're still waiting. It's actually a good sign, nobody wants junk.

At least there is a photo now http://www.44mag.com/product/6_8_25_magazine/6_8_ar15_magazines
