The spring to spacers thing isn't exact, but certainly dated. The power feed is a level 7 feature. That came out the same time as the crown point barrel milling. The wear on the sear doesn't look like wear as much as someone polishing the edges off, which could lead to excessive wear, so just keep an eye on it. If this were considered a "mostly factory" mag, I would venture that it had been a level 5/6, and updated after AGD caught up on the crown point barrel ano business.
Still, it is a mag and could have been conceived in a nice parts box. Personally, I have taken out a PT spacer and replaced it with a spring when I didn't have the right spacer on hand.
PS. That reg seat is nasty and doomed. It may last a few games, but get a new one soon. Garage heat and the old gun oil we used to use kills urethane as well as lots of other seal stuff.Last edited by Spider-TW; 06-19-2014, 03:50 PM.Comment

Spider pretty much summed up what I was going to say.
The mag I purchased in 1993 was a level 7 and had all the same features. The valve is clearly a level 7 vintage based on the look of the front of the valve chamber. A powertube spring came in the early level 7 mags for a few years. The powerfeed bodies and crownpoint barrel were stock items on the level 7 mags as well. Mine even had the same backbottle ASA.
The drilled back was an aftermarket modification to help with airflow because the two holes didn't line up on the early valves. They used indexing on the cnc machines so that the threads could be cut identically so that the holes could be drilled to line up on later valves.
The original sear has been modified by filing the side of the area that catches the bolt. This gave less surface area to rub which reduced friction and made the pull easier and smoother. It also reduced the wear area and caused the sear to wear out sooner. Its probably a good idea to replace the sear with a new one.
Yes, that regulator seat is bad. It definately needs a new one of those.Except for the Automag in front, its usually the man behind the equipment that counts.Comment
