About half a dozen POF's, all of which never gave any problems and are still going. Rifle problems are fractured receiver covers, fractured bolts, fractured rollers, fractured return spring arms (rimfire semi-autos), fractured pins, burred out trunnions, etc, as well as all the other problems you mentioned. A good number of H&K rifles were used by the venison recovery industry and were found wanting compared to other rifles, but, to be fair, these rifles were all firing many thousands of rounds. By comparison the FN FAL would go through several re-barrels without breakage over several hundred thousand rounds. With our Special Forces the H&K MP5's usually crapped out within a year. H&K offered NZ free military rifles some years ago provided we signed a long-term service contract. The offer was refused.
