i suggest for E10. A-Tac FG its on amazon for no more than any other camo. its about 50 or 60 for a top and the same for the bottoms. also, if you want more operator looking kits they have that also. it can fit into a budget kit just like the others.
ATAC AU is allowed for E10 the FG isn't because obviously it'd be easily confused with PSA / CoST.
