Hello, new here.
Looking at buying the matrix mp40 and, along with upgrading the internals, I plan on modding the exterior also. Wondering if:
- there is a picatinny top rail system in production or if I would have to make something custom?
- suppressors/ tracer units can be added?
- the internal upgrades I should make on it.
The mp40 for reference:
