This is what 2A Armament says :
The 2A Armament™ Titanium takedown pin set features a through drilled design for maximum weight savings in a standard .250 pin size. The head of each pin also incorporates a pocketed feature to reduce weight. Using certified U.S.A. 6AL-4V Titanium these pins weigh in at 0.18 oz total for both pins combined. The 2A Armament titanium takedown pins are aesthetically pleasing on both our BALIOS and BALIOS-lite receiver sets, as well as other vendors product.
