WAs hoping someone did a mud test of VHS2...this is really interesting.
Was expecting similar result, (also it was similar to kind of failures that X-95 and AUG faced i.e. ingress from charging handle side)
like, outside gunk won't affect the working parts inside receiver but would potentially fuck up the trigger extension etc in grip section; since the charging handle slot is open type,
but since that opening is on top, it is less likely to come in contact of stuff on ground in normal handling, also when put on sides the opening is kinda slotted in centre side of weapon from cross section etc so there is still some material between opening and ground,
so in practical purposes rifle is fine enough for service,
if they wish to improvise it they should just attach a sliding metal sheet like thing to cover up that slot, it is non-reciprocating type charging handle after all...
