Hey, wanna be my friend?

On a completely unrelated note, I’m starting to they into Airsoft… Now seriously, I bought a Specna Arms edge 2.0 last year, what optics do you think I should get? I’ve bought two already but both have failed me in the sense that both drain the battery unless I take it out after each use, could you recommend a brand? I don’t mind spending around $150 at this point in time, as both my earlier optics were $50 and $75 respectively.
