The product still chews up nozzle springs. Their “redesigned” nozzle guide failed after 100 shots. Both that were included had the same issue. Customer support recommended me modifying the nozzle return spring to prevent this. IMO that’s unacceptable. It should be plug and play and work better than or equal to the stock BCG
Build quality looks really impressive.
Comes as an complete set, except the nozzle.
The weight is indeed much lower and rate of fire increased. Gas efficiency not tested yet.
Seems very solid after a couple hundred rounds, minimal wear visible on the bolt catch or hammer ramp. Rate of fire in Auto is now pretty ludicrous, has made the MP7 very snappy in Semi. Seems built to last.
JP ver. MP7A1 with HFC134a is compatible,operates smoothly.The black finish is also good.
