The UFA-S Ultimate Forward Assist is made from Chromium Molybdenum Steel, and it comes with a high-quality QPQ Nitride finish for added durability and corrosion resistance. Moreover, the main plunger spring used with this forward assist is manufactured with a stainless 316 music wire, which offers better performance.

The design of the forward assist cap has also been improved. It has a slimmer profile for a more seamless design, which also decreases the chances of snagging. The cap also features exterior surface knurling, which allows you to engage the forward assist with or without gloves positively.
