if you looked at the second picture that i attached, you would see a different style of the magazine, different details, i personally think this would be a good weapon, but here is another suggestion for the pack:
an M9 Pistol and/or a USP .45 Pistol here are pictures, the first is the M9 and the second is the USP
Way to not even read my post, the mag is a different style of mag that the SCAR can also use, detailing it in blockland also would be close to impossible, the details are different yeah but, the modeler most likely won't give the model a huge level of detail so, it'd be stupid for him to make it.
btw, the whole Masada is based off the SCAR and other guns. It's got a SCAR upper receiver, G36 hangaurd etc.
M4 plox? Beowulf? Scar-HL?
Anyway, great job
M4 exist in blockland, No such thing as a Scar-HL.
