The PTW – Professional Training Weapon – from Systema is built to look and handle like the real thing, and its external parts follow the layout of the M16/M4 family. Here you will find the external parts that hold the handguard and barrel in place, and that can wear out or get lost during disassembly.
The PTW – Professional Training Weapon – from Systema is built to look and handle like the real thing, and its external parts follow the layout of the M16/M4 family. Here you will find the external parts that hold the handguard and barrel in place, and that can wear out or get lost during disassembly.
The range is mainly genuine Systema parts: delta rings for the XM177-E2/M16-A2 and for the M16-A1/VN/CAR-15, a handguard slip ring, a barrel nut spring (weld spring, 4 layers), an E-ring for the slip ring spring and the magazine catch button. There is also a steel bolt stopper for the PTW.
What to look for
Model: Delta rings come in different versions for A1/CAR-15 style and A2/XM177 style – choose according to the handguard you have.
Set or single parts: The slip ring, spring and E-ring work together. If you replace one, check whether the others are worn too.
Steel over standard: A steel bolt stopper is an obvious swap if the original is worn.
