Two entirely different roles bud.

According to respectable resources the 6.8 is being used more than you think. Stop by the 68 forums sometime and find out for yourself.

Just shot some 123 gr Hornady Z Max today with 26.6 gr of H 4198 in Winchester brass. .850" 5 shot group at 100 yards using my 16" ARP x39. 3 shots went in the same hole. I like it.

Ran the new CPD 28 rounder yesterday. Pulled the trigger as fast as I could and it fed flawlessly. The rounds don't nosedive with this mag. The new design keeps the bullets pointed nose up.

My 7.5" x39 runs 123 gr @ 1900 fps. I averaged around 60 fps loss per 1 inch of barrel length.

So, back on track, have you ran the new CPD J mags yet? Mine should be here in couple more days. As soon as they show up I'm going to load them up and test them out.

Well, as always I shouldn't believe everything I read on the internet. Some folks on another forum were complaining about the newest generation of .308 P Mags not working very well. One fella apparently spoke to a Magpul engineer at a local range about the issue and the tech mentioned they were releasing an updated follower and spring to fix the so called reliability issue with the newest generation of .308 mags. Maybe it was all a crock of sh!t. Didn't mean to ruffle any feathers hoss.

I don't own any and don't plan to. To many bad reviews with Magpul .308 mags. They work well for the 5.56mm and that's as far as I go with them.

I've got 6 of the 20 round C Products Defense SR-25/.308 mags and they are awesome. Quality is second to none and function is spot on. I have tweaked the feed lips up a little on all of mine to help aid in the bullet aiming more upward towards the chamber. It is probably not necessary for proper function but mine feeds flawlessly. These work great in my PA 10, cannot speak for other AR 10's. I bought 1 to start with. When i decided it was GTG I purchased more.

Just ordered 4 of them. Wish he would hurry up with the new 20 rounders also. Took my 16" ARP x39 out to 400 yards today, dialed in the dope on my 3-9x Trijicon Accupoint, banging steel all day long.

LMT is making x39 bolts again. I'm going to order some in the near future. From past research they seem to be indestructable. Luckily I was able to get 2 ARP x39 bolts before he stopped making them. They are pretty strong as well.

Chad at CPD has been giving us the ole "they'll be shipping next week" for like 6 months now with these mags. I can't wait to get some of these new 28 rounders. Finally.

Depends on the gas port size. Both of my x39 builds (16" ARP and 7.5" Tactical Ammunition barrels) run red Sprinco springs and H2 buffers

I've made a homemade jig like this one here for actually drilling non dimpled barrels. Works like a champ. http://i369.photobucket.com/albums/oo134/rlr350/Slide3.jpg http://i369.photobucket.com/albums/oo134/rlr350/Slide4.jpg http://i369.photobucket.com/albums/oo134/rlr350/Slide5.jpg

Chrono'd these guys today. 43.7 gr of RE 15 in LC brass, 2520 fps out of my 18" PA 10. They're a little warm. Heading out to a 1000 yard range next Saturday. Should be great.
