Like-new Gas Blowback HK416 GBB with V3 Nozzle steel bolt, a lot of new accessories, tuning airsoft rifle for ages 18 and over, 6mm BB

Here, the bolt has been replaced with one made of steel  (198€) with the V3 Nozzle,  non-adjustable.  I took over the set a few years ago, it was partially disassembled and after reassembly it turned out that the BB's do not leave the barrel with full power.  I could measure a max of 40m/s,  irregularly,  sometimes no BB comes out or only at 11m/s.I have tested different gases, everything is clean, the seals are fine, the magazines should also fit,  it seems to seal well to the nozzle, see photo. I think the nozzle is the problem here.  But I have no desire or time to deal with it further. There are many new tuning parts included.Including silencer, scope,  high-quality     2-leg, including 3 additional magazines. All magazines are sealed. The case is also included!Otherwise in excellent condition, see photo. Delivery includes everything as shown.Sale is expressly as defective!The high price is made up of all components...Extra magazines,  new tuning parts, steel bolt, etc..
