Phase 5 WSI just introduced a new Mini Hand Stop. The new Mini Hand Stop comes in an MLOK model and a Direct Thread model. The direct thread model works with the Phase 5 LPSN handguards or any rail that has #10-32 tpi threaded holes that are 1.576 in. apart (such as the Centurion Arms CMR or KAC URX3.1, etc). Each model is available in Grey, Black or Red.
The new Phase 5 WSI Mini Hand Stops are available now. Direct Thread models are just $25 and MLOK models are $35.
