Fps is proud to present its stainless steel precision inner barrels line 100% MADE IN ITALY.
This inner barrel is produced starting from a precision drawn micro stainless steel tube that is subsequently subjected to the following processes:
- CNC machining
- straightening calibration
- internal reaming
- ultrasonic polishing
The shape of the hop-up window has been designed to be compatible with both normal and "flat" rubbers.
Stainless steel ensures maximum mechanical resistance and total absence of surface oxidation unlike aluminum or brass.
Another great advantage of AISI 304 is that it can be easily cleaned with metal brushes without being scratched, thus ensuring the most complete removal of any plastic residues present on the internal surface of the hole.
