FPS Softair brings you the Polymer Piston w/Steel Tooth Rack for Marui NGRS SCAR-L/H, featuring a technopolymer body and a full rack of steel teeth for a good combination of high strength and low weight.
The loaded technopolymer assures great mechanical resistance and dimensional precision. The tooth rack was manufactured through the use of MIM (Metal Injection Moulding) technology since this production process guarantees dimensional accuracy and sturdiness equal to those of solid machining.
The metal injected is SAE 4650 steel, currently considered the best for this type of use. The sliding guides are designed to minimize friction and hold the lubricant for a long period of time, so you can be safe in the knowledge that your TM NGRS SCAR will have reliable and long-lasting functionality.
