Within the past couple of months, I've seen two automags for sale (both sold, much more than I'd have paid considering) with the bolt rotation pins welded in. Any idea why anyone would do this? I've had all the ones I've owned stripped all the way down and I can't see a way to take them apart in this condition. Which makes me wonder how many others are like this because many people selling them don't show pictures with the barrel/extension removed. Roger

| It sounds like you're talking about Model B (solid bolt) guns. The Bolt Rotation Pins were welded in place and the solid Bolts were installed from the front, having an extended slot in the Bolt to accommodate assembly. |

What he said... I love the Solid bolt, much harder than hollow bolts. In the past, I hollowed out solid bolts, to fit both hollow and solid bolt pistols. Solid bolts are made of a hardened tool steel and last forever. Eric

Removing the solid bolt from the frame can be a bit tricky.  The removal of the solid bolt from the frame is
rather straightforward until the last step.
After removing the cocking piece, firing pin, recoil rods and springs, the
solid bolt pulls out of the frame in a forward motion. As you pull the bolt forward, the bolt ears (on
the rear of the bolt) straddle the bolt rotation pins and then the bolt stops. It won't move forward or backwards. The
bolt safety tappet, part #44 has
risen up and is sitting in a relief in the rear of the bolt, in front of the bolt ears, locking the bolt
into this position. Before removing the solid bolt, remove the right
grip. With your finger, pull the trigger
bar down. It is part #36.
This allows the bolt safety tappet, part #44 to drop out of the way so that the bolt can easily be pulled
forward and removed from the frame. Most owners of a solid bolt gun already know this. Don't mean to offend......Bruce ------------- An armed society is a polite society. |

thanks! i was not at all aware of that. Every one i had was by dumb luck pretty close in serial numbers (and all TDE El Monte). That does explain why the welding was so extremely well done. Roger

I'm glad I asked this question as I just bought another and it's made this way. Odd, as i'm pretty sure the serial # is between 2 others I have that are the other version. This one has a North Hollywood marked barrel which may or may not be original to the gun. Roger

FWIW, not all B-Series guns had solid bolts installed. Serial Number B00370 had a standard bolt in it and NO evidence of any left over weld evidence on the hoop. Tony ------------- Run it up, until you blow it up, then back it down a bit. |
