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. This oversize tactical bolt knob features 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. Features 1/4-28 threads and slightly reduced overall size (compared to our 5/16-24 model) to better fit smaller diameter bolt handles such as the Winchester M-70 and Savage 110. Mil-A-8625 hardcoat anodized, matte black finish.
Installs easily on 1/4-28 pre-threaded bolt handles; requires gunsmithing for non-threaded bolt handles. See our recommended installation procedure in the tab to the right, or for professional installation please feel free to contact our recommended gunsmithing services on our ‘links’ page.
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.
