A safety selector assembly for a firearm is provided. The safety selector assembly can include a core member and one or more levers removably coupled to the core member. The core member can include a first end and a second end. The core member can also include at least one shelf recessed into the outer surface of the core member. The core member can also include at least two throws disposed on the core member and between the shelf and the second end of the core member. Each throw can have a different angle of rotation between positions for allowing and preventing movement of a trigger assembly on the firearm. The core member can also include a first post on the first end and a second post on the second end of the core member. A lever can be rotatably coupled to each of the first and second posts.

Safety selector assembly and associated accessories

According to embodiments of the invention, an impeller includes a hub, and a plurality of radial blades for drawing the air inflow axially through the hub and delivering the drawn air radially towards the outside. A ring is attached to one or more tips of the plurality of radial blades to block a portion of the tip toward the inlet side of the impeller. The preferred blockage factor, which is the ratio of a height of the ring to a height of the tip, is approximately in a range between 30% and 40%. By blocking a portion of the tip toward the inlet side of the impeller, the low-momentum flow zone toward the inlet side of impeller is blocked, while the high-momentum flow zone toward the back side of impeller is enhanced. As such, the performance of the impeller is enhanced.

Blower impeller with partial tip blockage

A block game includes thirty-six indicia blocks. Each of the blocks has an indicia face which is divided into two square faces. In each of the square faces, dots are arranged in three horizontal rows, with each row having one or two dots. Moreover, the dots on each indicia face are arranged symmetrically about an axis of symmetry of the indicia face. In play, two indicia blocks are positioned adjacent to one another in such a manner that an edge of the first square face which has one dot lies adjacent to an edge of the second square face which has two dots, or vice versa.
