This is an exact clone of the handguard that came with my MKE AP5-P (MP5K). I modeled this to use as a base for further handguard mods and designs. Included are the STEP files of both the "finished" version and the "base" version. Only difference between the two is the "base" version has no chamfers/fillets so it easier to mod. I recommend you print all my designs with 100% infill.
