Show Your Custom Rifles With Granite Mountain Arms Actions

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 ?
 
built in 2007, my pair on GMA African size actions, custom integral barrels, iron sights only, Luxus walnut, leather cover recoil pad, 25" barrels, nice handling for me:) Top is 505 Gibbs, bottom 416 Rigby.

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.

Jake, Sorry to bug you again. I was wondering if you could share a. couple actual pics of this crossbow with me?

Xpedition Archery USED Scrapeline390X Sniper Gray Crossbow XACW1001 - Light Wear - Needs Bolt/Arrow Guide Spring UA5689​

If it is in a decent shape, would you be willing to sell it for $100 shipped? IS it missing the retention spring that goes over the bolt?
Thank you Ferenc

Good morning John, I just read your setup procedure for the northstar duplicator ator. I found it very hand and I did learn some things. I have the same machine and I am having a problem i can not figure out and was hoping you could shed some light on the subject.
