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.

Safir seems to also be working on their own bullpup rifle that they’re calling the T-14 rifle. Not much is known yet about their new T-57 upper/rifle or T-14 bullpup rifle other than what was posted on their website.
