Sure-Grip™ CNC Machine Cut Texturing for Fast, Reliable Cycling.
Precision Armament Tactical Bolt Knobs are fully machined from lightweight high strength 7075-T6 aluminum bar and feature high quality Sure-Grip CNC engraved texturing. Sure-Grip provides a dependable non-slip surface for fast, reliable cycling without being sharp or abrasive like knurling. Available in 1/4-28 and 5/16-24 threads and is slightly reduced in overall size (compared to standard oversize knobs) to better fit smaller diameter bolt handles such as the Winchester M-70 and Savage 10/110 rifles. Mil-A-8625 hardcoat anodized, matte black finish.
Available in 5/16-24 and 1/4-28 threads. Installs easily on pre-threaded bolt handles; requires gunsmithing for non-threaded bolt handles. For professional installation please feel free to contact our recommended gunsmithing services.
Also see our larger oversize TBK-6 tactical bolt knob which features standard 5/16-24 threads for Remington 700 and similar size bolt handles.
