Double eagle m4 questions

Hey I’m thinking about getting a double bell xm177. I like it because it’s the only one I found that doesn’t have the forward assist and also shoots about 430 out of the box. Is it worth it? Would it be something I would eventually be able to build well and throw something like a gate titan in? Just kinda have an idea in mind and that rifle fits the look perfect and is really cheap but also full metal
