Another extremely rare device made by Alpha Chase Brass in Waterburey CT.

This is a brass deadblow operating guide installation tool. Predates it's design purpose by almost a hundred years. Talk about pre-design and forward thinking. Note the blasted matt finish. Eliminates unwanted reflections when installing op rod guides by candlelight. A real sight saver.

Might need one of those. Finally got a H&R marked receiver to go with my all NOS H&R kit.

I tell you, if you have a tight op rod guide and want it to come out just right, you can't beat a chunk of pipe with the proper ID to set them.
I grease up the barrel and let her go.
You need to start with a barreled receiver, then temp install bolt, op rod and gas cylinder. Mark the loose guide at a point where piston tail and op rod line up.
Easy squeazy, knock the guide down square until guide pin hole lines up.
Using the pipe, the guide settles down square and without rotating as you drive her home.

Never seen one of those. Thanks for sharing. If you ever run across another, let me know.

Any chunk of pipe with the correct ID will do the job.

Sure is nice to have the guide slide on nice and square.

See a lot of guide beat to heck with guys hammering them on with a punch.
