Since you're asking for HK and clones: SP5K, zero break-in. Fired it with the factory light oil for 300 rounds, cleaned it and lubed with CLP, and another 600-700 rnds later, and several cleanings, not a single failure of any kind. This is running mostly 3RB and a few mag dumps along the way. MM welded HK bolt carrier ramped for sear operation and factory SP5K barrel.
Average break-in period for MP5/K HK/clones/copies/variants
I'm curious what others experience is in regards to what your break-in period was for any/all of your MP5/K variants/clones/copies.
My MKE Z-5RS was about 300-400 rounds probably before I stopped seeing occasional jams.
I was reading about someone with a SP5K having jamming issues with a new gun and I couldn't find any discussion about average break-in period, so I thought I would start a thread.
Reply with the make/model of your gun, and now many rounds you ran through it before you stopped seeing occasional jams. No rumors please, only reply if you have direct personal experience with a brand new gun.
