I Need help and advice for a high poly weapon model I made

[zeph10]

Basically I decided to model a m16a1 and so I started off with the high poly. Tried my best to keep the topology as flexible as possible but it seems it takes me forever to remove edgeloops. I only managed to get to 34k tris removing edges and also taking down some of the subsurfs I had. Without it the model gets some shading problems that don’t look great so on some parts I have no choice. Perhaps I didnt optimize it well or my topology is just bad atm. I was wondering what anyone else thinks I should do.

Should I just retopo the whole thing to get a better result for the low poly and just bake this guns details to that?

Ill leave a few photos of the HP gun and the blend file here:

I’m currently trying to model another gun atm (UMP 40 since it seems a bit less painful and because I’m in college). Anyways here are some wireframe close ups. I have subsurf on but not applied yet. This is the topology without all the density and note some parts I may have to keep subsurf on level 1. The parts that look really bad without subsurf are circled red.
