Thanks DonRow. I just got her a few months ago used. I added the optics, grip, replaced bi-pod original one was not so good, got a Bravo Co. gunfighter charging handle, KNS anit-roatation pins. Tac light came with it and a laser which don't have on right now. My 2nd AR. First one Olympic Arms long time ago, had bad luck with it. It was used to maybe that was problem. This spike's is great shoots nice, never had a problem.

Nice! Never shot 6.8 and don't know a whole lot about the round. Will that upper work with a 5.56 lower?

Yep

The 6.8mm SPC cartridge was designed to address the deficiencies of the terminal performance of the 5.56x45mm NATO cartridge currently in service with the U.S. Armed Forces.[6] The cartridge was the result of the Enhanced Rifle Cartridge program. Participating in the program were U.S. Special Operations soldiers, as well as armorers and other technicians from the United States Army Marksmanship Unit.[7] The development of this cartridge is unusual and interesting in that it was designed by actual shooters in the armed forces, instead of by industry professionals. The goal was to create a cartridge that would bridge the gap between 5.56mm and 7.62x51mm NATO.

The program started the design by using a .30 Remington case, which was modified in length to fit into magazines that would be accommodated by the magazine wells of the M16 family of rifles and carbines that are currently in service with the U.S. Armed Forces.[8]

In tests, it was determined that a 6.5mm projectile had the best accuracy, but a 7mm projectile had the best terminal performance. Further tests showed that a 6.8mm projectile was the best compromise between the two, providing accuracy, reliability and terminal performance up to 500 meters. The combination of the cartridge case, powder load, and projectile easily outperformed the 7.62x39mm Soviet cartridge, with the new cartridge proving to be about 200 ft/s (61 m/s) faster.[9] The resulting cartridge was named the 6.8 Remington Special Purpose Cartridge due to the size of its projectile and the fact that it was based on the .30 Remington case.

Wow, great information. Do you think the military will switch to this cartridge or stay with 5.56 or will it be something that the SOF will use in their inventory?

The military abandoned the 6.8 project years back. It was then left to the commercial market. Now the military is in a long term evaluation of the SOST round as a new 5.56 model to replace M855.
