Size Chart



Magnum RPR (.338 Lapua & .300 WSM) owners can now upgrade with our new RPR Mag release extension that is based on Americas best selling short action RPR Mag release extension.


Magnum Ruger Precision Rifle shooters can easily make rapid and efficient magazine changes while maintaining their strong-hand grip. Machined from 6061-T6 aluminum, the new Catalyst Arms Magnum MRE is lightweight and installs with a single screw without any modification or disassembly of the rifle. Designed to be easily accessible yet snag resistant, the Magazine Release Extension’s sits forward of the trigger guard with a profile that matches the sides of the magazine well. The Magnum Magazine Release Extension has rounded edges to prevent inadvertent activation from contact with gear or the use of gloves.

    Works as advertised to aid in magazine change for ,338 RPR. Got mine in black because I favored functionality over bling.
