In preparation for this summer's 1930's reenacting season, I decided to change over my second 1921, also, to 1928 internals, to slow things down so the crowds can hear the individual shots better, and so the shootouts would last just a few seconds longer.

This was much more difficult than the first changeover, since I had only a cast 1928 actuator, which required 3 hours of hand filing, and a standard 1928 buffer pilot. I really missed the Gunmachines telescoping 1928 buffer pilot I have in the other gun.

I know that Gunmachines hasn't received unqualified praise from all readers in the past, but that buffer pilot has really made a difference for me in putting the gun back together, and reducing the chance for kinks.

Anybody out there have a Gunmachines telescoping buffer pilot they want to sell, or is anybody making them now?

Have 6 great pictures now on Photobucket that show the whole 4-piece setup, but I am too stupid to press the right combination of buttons on this forum and the buttons in Photobucket to get them here. Have a note in asking for help, and when that arrives, so will the photos and narrative. It is a lot more complicated of an item than a single shaft, turned on a lathe. Thanks.

6 pictures of the Gunmachines 28 telescoping buffer pilot. The small protrusion does telescope almost entirely into the body of the pilot for installation in the gun, but then extends into the body of the buffer to keep the spring from kinking. The pilot has at least 4 parts 1. Telescoping pin, 2. Pilot body, 3. Spring, and 4. End cap to keep spring in body. These were turned out by Gunmachines in the early 90s. I'm not as interested in someone beginning a new run, as I am in buying another one which is out there already, from a "purist" who doesn't want any non-authentic internals, or who doesn't like Gunmachines any more. I'm out for functionality and fun, and the original internals will go back into the gun when it is ready to sell. user posted image user posted image user posted image user posted image user posted image user posted image Thanks to all for help in posting. I did shrink to 800x600, but they are still big to view.

Reenactor: I do have a Gunmachines telescoping pilot that I'm willing to sell, if you are interested send me an email with your contact info and we'll work something out.

Thanks, Phil and Mike. Deal done. Will now have BOTH 1921s shooting blanks at a slower rate for the benefit of the audiences this summer. First shoot in Gibsland, LA May 21 for their local Bonnie and Clyde festival.

Looks very similiar to an M1/M1A1 recoil rod and buffer. Anybody else have any info that explains what is accomplished by modifying or changine to this style?

The difference I have seen is that the last 1 1/4" of this longer rod telescopes into the body of the buffer when inserting the buffer/spring assembly into the back of the actuator. It is longer than a standard buffer when you are compressing the spring onto it, and getting ready to install the spring/buffer combination, so it acts as a guide for the spring (the end of the buffer and spring are actually inserted into the actuator before you swing the assembly down into place in-line), THEN it compresses to standard length when installing (as you get the assembly in-line and then release it), then extends after installation. The net effect of this is that there is no potential for the spring to kink out of where it should be, that is, it is always contained around a part of the buffer. As can be seen in the picture of the buffer and spring after installation, there is still the potential for the spring to compress and rub sideways (PK mentions this in his post on another thread as a potential wear issue to be alert to), but at no time is it "loose" to bound sideways out of the gun in an install, or to kink over at 90 degrees when you get it to within the last 1/2 inch of installation as can easily happen with a standard 28 or M1 buffer. Then I add a PK 28 buffer pad to the standard mix. I am over-buffered, but there are only so many 21s out there.
