We have a fail rate on rear guides of <1%, but some just fail in the first 50 or so shots due to imperfections in the plastic. The next biggest cause is the spring having burrs or rough spots which score a line similar to a glass cutter which fails under pressure. Either way they all have a lifetime guarantee, had you let us know it would have been replaced straight away.
