PTR Industries, known for its roller-delayed platforms, has a new 5.56 NATO-chambered model out for 2024 that takes STANAG magazines. Here are the details on the company's new PTR 63.

Unlike original HK-type roller-delayed blowback firearms, PTR firearms include a Picatinny rail permanently attached to its upper receiver. In the case of the PTR-32 series, the rail is 6.88" long.
