CMMG are taking pre-orders for their new stripped lower reliever that is compatible with DPMS Panther Arms .308 AR-10 style upper receivers. The lower uses H&K G3 magazine which can be bought for under $5!

Some minor modifications are needed to the upper to accommodate the larger magazine. The price is $449.95 and it can be ordered online.

Many thanks to Tom for the info.

Albert @ The Rasch Outdoor Chronicles has reviewed the CMMG 28 round Immortal magazine for the AR-15:

CMMG claims that no other magazine offers greater performance under extreme conditions. It has their new stainless steel anti-tilt follower which features superb stability, minimal drag and unmatched durability.

The new CMMG braided wire spring gives 40% additional pressure over standard USGI springs. A nano-ceramic plated braided wire spring protects for over 400+ hours against salt sea spray.

CMMG have announced an .50 Black Powder AR-15 Upper!

To fire, the powder charge and bullet are loaded via a ramrod. Using a standard magazine with a single shot follower, an unloaded 5.56 case is loaded into the mag, inserted in magazine well and loaded just like a standard rifle.

Once the rifle is fired, the empty brass is ejected manually and then reloaded.

…

It is a modified .223 case that uses a 209 primer. Currently .50 cal. Should have pricing and other specs tomorrow.

Interesting! As one commenter said

Can you imagine the face of an unsuspecting
game warden the first time he runs across these..

They have yet to announce pricing.

UPDATE

This isn’t a loaded case, it is a 209 primer in a piece of .223 brass. There is no way a live round or a blank will load into the “chamber”.

UPDATE

A video of it in action. Actually, it looks pretty good.
