AR-15 Magazine Follower

AR-15 Magazine Follower by crank Feb 22, 2011

Description

This is a basic AR-15 magazine follower. It fits any USGI magazine. NOTE.... This is NOT currently an anti-tilt follower and this is a work in progress. I am implementing anti-tilt functions that will be in the next revision, plus a few other changes to make it "beefy" and a magazine spring catch. The current one feeds and functions well, I put 100 rounds down range with it, no jams.... YET. Also in the works, is a whole printable magazine and spring.

The anti tilt is nearly complete. I just need to adapt the other one that I made for the printed mag and upload it.

Instructions

1) You Have a need for an AR-15 Follower :) For example yours is busted on your last magazine and there are zombies outside of the door.

2) In a case with Zombies, make sure you can hold them at bay for approximately 30 minutes for printing +5-10 minutes for cleaning and sanding. Perhaps some pieces of wood nailed to the windows and doors would do the trick?

3) Download the STL ... if Zombies have not destroyed the needed infrastructure.

4) PRINT AND HOLD OFF THOSE ZOMBIES!!!

5) After the print is successful, clean with some 150 grit sandpaper and finish with some 400-600 grit sandpaper. Make sure it is smooth and any hanging plastic is taken care of. We wouldn't want any round feeding malfunctions while battling Zombies?

6) Install into a USGI magazine and load her up. By now, those boarded up windows and doors may have been compromised.... but now you can defend yourself against those Zombies with your AR-15.
Very nice, I'd also like to see one with anti-tilt

i think its stated ON THE UPLOAD PAGE that no weapons are to be uploaded here on thingiverse..

so please remove your 3D parts that are so closely related to killing people

You posted this exact same commend on the printable magazine page: thingiverse.com/thing:11636

Why are you trying to piss on people's parade? Folks with 3D printers are like the nerdiest of the nerds; what are you so worried about? Why judge?
He is just a sissy

Very cool. I look forward to your anti-tilt and full mag
I see this as a good use for 3d printing.

Not so sure about a full abs mag though.
Excellent and I love the instructions. I am guessing that you might want to make these and have them ready for the zombies, instead of waiting for them to be pounding down your doors.. :-P

Similar to randyy's note, I am struggling with this from a real world use "life/death" perspective. Although, I am guessing that the manufactured followers are probably not that much better.
:-D
Weapons on thingiverse. Hum, thats a hard one. I have seen knives printed and most would consider those weapons. Should the thingiverse community discourage weapons related items from being posted? My thoughts are that we all have different interests that can relate to the home production of items related to those same interests. What I would not like to see is some kind of censorship with regards to what an individual sees as "offensive". I agree with some others that ranking something low just because of political beliefs is not in the spirit of this community. To me, items should be ranked by the quality of execution. Since I have yet to study the particulars, let alone print this part, I will not rate this item.
I have no ethical delema sharing weapon parts on here, I doubt anyone is going to not rob a bank because they couldn't find a model for a magazine follower to print on their Prusa. It will be a long while before you can manufacture a whole firearm on home CNC machines and even then I am not the least bit worried about people who are smart enough to do this having guns. People who are intent on hurting others have plenty of resources that are much more effective toward their purpose. Depriving ourselves of cool parts like this serves no use in keeping weapons out of the hands of those who would harm people maliciously.

I completely agree that censorship is one of the worst things that could happen to this awesome community (the other being DMCA take down notices).

My 2 cents worth take it or leave it.
I've rated this a five to offset Marcus' philosophical objection to a part, which has no basis in the usability or practicality of a thing. There are many things I do not like on Thingiverse but I'm not going to attack them. (Although I shoulda marked it a one cuz you're promoting zombycide.... take a closer look at my avatar) :-D

Nice idea and looks cool, but in all reality, I'd never repRap a life or death part like this, especially parts that are designed to channel high tension, directed, low-order explosives. Maybe for target shooting, but I'd still not chance it. Anyone wanna make parachute linkages on your 3d print
er?
Very, very well done! May have to try this for my Mini-14!

Just a few thoughts:

When you work on the complete magazine, consider printing a mandrel to wind your own spring. You can find pre-hardened/spring-tempered wire to make your own gun springs at Brownells.com.

With sustained fire, the inside of the receiver may become hot enough to soften the lips of a printed ABS or PLA magazine. Add the force of 10 to 30 rounds under spring tension, and the lips of the mag are likely to deform into the receiver. I believe that most plastic mags are made out of heat-r
esistant thermosetting plastics like epoxys and phenolics. If it turns out that the ABS/PLA doesn't work, you could consider printing a Mold for the magazine. Filling the printed mold with something like glass-filled epoxy would then give you a strong, heat-resistant mag. If you decide to try thi
s route, I have had good results with sollercomposites.com/ and fibreglast.com for resins/composites. BTW, I have no affiliation with any of the above companies, other than as a customer. Best regards,

Thanks :) . My magazine design is currently only 5 rounds. I too worry about the heat of sustained firing and the exerted loaded spring force on the magazine feed lips. So, I thought I would minimize these issues with a 5 round magazine to start with. I LOVE the molded glass filled epoxy idea if the ABS doesn't work or as an alternate path. Perhaps only a portion of it would have to be molded or maybe the whole thing depending how things go. Actually, I have some experience in this area and have been a customer of fibreglast for years. I have variety of chopped and milled glass fibers sitting next to me in my garage and some a number of different resins too. So, plan B is ready to go :)

Thanks for the heads up about the spring tempered wire at Brownells. I will have to look into that.
I'm not particularly thrilled to see weapons and weapon parts here.
@Marcus ... You know what I do when I see something I don't like on here, I don't look at it, I definitely don't click on it, and I sure as hell don't comment on it. I'm not sure what you are trying to accomplish by giving 1 star ratings and doing what you are doing. I am not sure why you hate some weapons and like others (Fridge Shiruken). I know there is a big difference between this and the fridge shiruken, but I've seen you make comments like this on things that are much more innocent. But all these comments seem to do is anger people.
A gun is a tool. A knife is a tool. This is just tool hacking.
I am not particularly thrilled to see a good part ranked low for political reasons. If you don't like the gun laws you are happy to battle against those who do in the political system but replacing an expensive part with a home made one is what this site is all about not political ranting.
get over it, 3d printers will be printing everything before you know it.. firearms are a recreational sport in most of the USA. these parts break and wear out there is no point in buying them when they can be printed. just like everything else on there.
love it, can't wait for the full mag. I have some plastic ones already but man, if I could print my own, imagine the savings!
