I was toying with an idea lik this since a time. My variation is slightly slower cause i choosed to add an AMS, but if u feel more comfortable in pure scout role, switch to a BAP instead. I feel that the ERLLas gives u firepower to harass from a far, or simply dig in for the often previous phase of long range fire in every battle, then close in to unleash the close-quarters little fury of this spec I also feel like this build can go really nice with MPLas instead of MLas, trying to decide if its better to loose 1/2 ton of each ammo or 2 JJs
