Safir Arms New AR-57 Upper And Bullpup Rifle
It looks like Turkish firearms maker Safir Arms is working on their own AR-57 rifle and upper kits that they’re calling the T-57. What’s a AR-57 upper? It’s pretty much an AR-15 upper chambered in the FN 5.7x28mm round and that uses the FN P90 magazine on top of the rifle just like how the P90 does.
