The PRIMER Containment Bracket is designed specifically for the PRIMER Arrow Rest to fully contain an arrow before and during the shot. The PRIMER Containment Bracket paired with the PRIMER launcher creates our Gravity Feed Technology which ensures the arrow will always be centered on the launcher when at full draw for improved accuracy. The Containment Bracket core is made from a durable woven nylon and is over-molded with a proprietary quiet material to reduce noise when the arrow contacts it.
