The ACR Sandfire comes with two more damage points, four more portability points, the same rate of fire, two more accuracy points, and one more recoil point, furthermore it comes with a desert, sandfire camouflage.
Statistically and gameplay wise, the ACR Sandfire is quite similar to both the M6A2-SRT and the MK16 SCAR-L, favoring more the style of the SCAR-L. Because of this overall similarity the popularity has remained rather low, with most NX users going with the M416 CQB, or a more popular weapon. Though one of its features is a quick reload, where the wielder inserts the magazine and is ready to fire.
The ACR Sandfire is the second Sandfire weapon, with the first being the SR25 Sandfire. Strangely, their camouflages are different, with the SR25 being just colored in desert color, while the ACR has a camo with several different colors.
Despite having 1 point more recoil than the GP-bought ACR, the ACR Sandfire's recoil pattern is totally different from the ACR. The ACR Sandfire's recoil goes up for the first few shots, and then diagonal, whereas the ACR goes sideways like the SCAR-L.
The iron sight of the ACR in game is flipped down.
During the weekend of 9/10/10, you could get a free 1-Day ACR Sandfire if you played 20 Elimination matches.
If you look at it, it doesn't look like sand, but more like a desert camo.
It has a different firing sound from the GP standard ACR.
