I saw a little tool that holds the upper reciever open - the Dewey Link or something? Uses the rear detent pin and hole...

However it was $20... a little expensive for what it is.... anyone know of a cheaper option that works? Or even one that I could 3D print with a MakerBot printer?

Or, do I just need to suck it up and buy the damn $20 thing Dewey link?

This would be stupid easy to design, print, use.

I can print it, but not create it... I would need a downloadable file that is already created.

It would be easy enough to make it out of a ribbon of sheet metal and a hole punch.

I also thought the various hold opens were too pricey.  I shall now make my own.

why not just pull both pins. Been working for over 20 years for me.

Because it's easier to leave the entire firearm "shot-gunned" in a fixed base.

One tip, if you do make your own, is to buy a clevis pin long enough to use for the pivot pin spring/detent install trick.

I wouldnt waste the time printing that.  Looks like a couple hours worth of measuring, CAD, and running the printer.

It'd be faster to just get a scrap of wood, drill 2 holes in it, and run it over the table saw about 8-10 times.  5 minute shop project.

ETA -
Took closer to 10 mins to hammer a quick one out of some scrap plywood.  You could make it look better if you cared to spend the time.
The saw and drill also work on aluminum, so you could use that if you wanted, too.

I use a vise and have a magazine block that I use very rarely. What I normally do is take my upper and lower receiver apart, clean everything and reassemble my AR.  I have a work mat that I use  and I have been cleaning this way since before I bought a vise and work bench.

Anyone know of an option I can buy for less than $10?

10 bucks is worth it to me to spend then spending time making something, I am def not as much as a tinker as some of you guys but am impressed by the simple ideas you Guys have
