Product Description
The UFA-S is precision swiss lathe turned & manufactured from certified 4140 Cr-Mo steel, giving improvements to strength, corrosion resistance and durability over the original materials.
- Parts are all heat treated to 48-52 Rc (Rockwell C). In addition, all parts are QPQ (Quench Polish Quench) Nitrided for improved corrosion resistance and enhanced lifespan.
- The main Plunger spring is manufactured with the improvement of Stainless 316 music wire (as per ASTM A313) for enhanced corrosion resistance.
- Closed-end coils are also used rather than the original open ends for improved seating and alignment. Springs are stress relieved and air-cooled.The Plunger Detent Spring is improved and manufactured from Zinc plated music wire (as per ASTM A288) for enhanced corrosion resistance.
- Springs are all stress relieved as per the mil specification.
- The assembly is retained within the upper receiver with an improved spiral design pin as opposed to a slotted version for increased strength and durability. Pins are fully certified by the manufacturer.
- The design of the Cap has been improved by reducing its diameter and snagging potential, creating a more streamline surface flow when assembled into the upper receiver.
- Exterior surface knurling around the cap’s edge allows for positive engagement with a gloved or naked hand while removing the circular ridge that exists on the current design.
- The weight of the assembly has also been improved to 20.227g (.7135oz) from 22.481g (.7930oz).
