The first one is for a 5.56 caliber. The second is for a 6.8.

Same lowers. Different markings.

Bottom line: there is no difference funtionally and legally.

I am not 100% correct, but I believe that Stag-15 is for 5.56mm and the other is for 6.8mm.

Basically the more expensive one shoots a bigger bullet.

Taken from Wikipedia:

The 6.8 mm Remington SPC is designed to deliver 44% greater energy than the 5.56 mm NATO at 100-200 meters.[4] When compared to the more powerful and well-established 7.62 mm NATO cartridge, the 6.8 mm falls short in all these areas, but has less recoil and is more controllable. While the 6.8 mm generates around 1,759 ft·lbf (2385 J) of muzzle energy with its 115 grain bullet (note: this figure is from an unrealistic 24" bolt-action test barrel), the 7.62 mm NATO (M80) fires a 147 grain bullet at 2,750 ft/s for 2460 ft·lbf of energy (838.2 m/s for 3335 J).

While the round is generally intended for use at shorter ranges, this handicap somewhat dampened the initial enthusiasm over the SPC round, and given competitors like the Grendel or improved 5.56 mm rounds an opportunity to compete for acceptance.

I guess they are identical then :confused:

The calibers/cartridges are different.
But if you are comparing the lowers, there are no dimensional or constructional differences aside from the markings.

In other words, feel free to build a 5.56/.223 chambered rifle on a 6.8 SPC lower or vice versa.

It cost Stag more to engrave the lower with 6.8 on the lower then 5.56 so they charge 20 bucks more.

8 is a really difficult number to engrave. It costs more. 5 is cheap.

In every way except the engraving they are identical. There are no issues with building any rifle (short of being an AW or MG) on a lower.
