For price 400-500$ range, you can get a fully equipped TM Aug A2 with mags and with a bit of upgrades... just deal with the sellers. They will sell it at lowered price for sure. I'm not comfortable with bullops guns , i just can't reload properly with them , not use to it maybe. The AUG's looks small but when using it, it feels very solid and big. It's a great CQB gun but can be upgraded to be great on ranges too

Overall a great gun if you want to be different from the others. butt stock is large enough to hold bigger batteries. Only issue you might encounter is losing the buttstock pad .... and i think its automatic only?
