Show Your Custom Rifles With Granite Mountain Arms Actions

[Hunter-Habib]

Granite Mountain Arms African Magnum Mauser actions are my #1 favorite actions for dangerous game magazine rifles in the entire world.

Mike Roden was trained by the great American gunsmith, Fred Wells himself. Forged and as strong as they come. In my humble opinion, it's the only action that's 100% suitable for a .505 Gibbs build due to the correct sized bolt face.

I seem to remember the bolt face on the 505 is 3/4 of an inch . A monster action . Was the GMA action based on the Brevex ?

Very good, PCC600 ! It was based on the Brevex M400.

PS Mike Roden loved the 505 Gibbs, hence the 3.85" mag box and 0.750" bolt face

Those rifles are great! I believe even the vaunted, cool and awesome Mauser Magnum action's bolt face diameter is .700, the same as CZ 550, Win Mod 70, Dakota 76, Ruger 77. I'm not 100% on all of those so somebody correct me if I'm mistaken. The .750 diameter is nice for the handful of 505 Gibbs shown on this thread.
