Description
Anyone who has built or broken down an AR knows the pivot pin dance: the spring, the detent, and the inevitable ping as it disappears under the workbench. The BAD Aluminum Takedown Pins in purple were built to fix that headache while adding a little personality to your lower. This is the full Enhanced Pin Set from Battle Arms Development, precision CNC machined from 7075-T6 aluminum and finished in a rich purple anodize that stands out against a black or FDE receiver.
These drop right into any AR15, M16, or M4 lower running the standard mil-spec .250 diameter pin holes, so if your rifle takes normal pins, it takes these. The heads carry a patent-pending design that gives you a much better gripping surface and solid pull strength without going the oversized route, so nothing snags on your gear. They actually sit a hair lower than mil-spec heads, keeping things clean and out of the way, and the takedown pin is shaped so it won't block a right-side ambidextrous safety lever.
What Sets the BAD Aluminum Takedown Pins Apart
The details are where this set earns its keep. The pin tips run about .030 inch longer than mil-spec, which gives you something to push against when starting the pins from the left side of the receiver. Both tips have a cone-shaped recess, so a punch or bullet tip seats in and stays put instead of slipping off and gouging your finish.
Getting the BAD Aluminum Takedown Pins Installed
The pivot pin is the part everyone dreads, and Battle Arms tackled it with an EZ Guide channel and a magnetic assist. The included neodymium magnet holds the detent and spring in place while you seat the pin, so no more lost parts and no more prayer to the gun gods. It is one of the smoother pivot pin installs out there, and once it is in, the purple finish ties a build together whether you are running a themed rifle or just want something better looking than gray steel.

Frequently Asked Questions
Will the BAD Aluminum Takedown Pins fit my AR-15?
Yes, they fit any AR15, M16, or M4 lower receiver built to the standard mil-spec .250 diameter pin holes. If your rifle uses ordinary takedown and pivot pins, this set drops right in. Note that the pivot pin is not compatible with the proprietary AX556 receiver, though the takedown pin still works there.
How does the magnet-assisted install on these takedown pins work?
The set includes a small neodymium magnet that holds the detent and spring in position while you seat the pivot pin. Combined with the EZ Guide channel, it lets you install the pivot pin without the usual launched springs and lost detents. It makes what is normally the most frustrating part of an AR build genuinely easy.
Are the BAD Aluminum Takedown Pins just for looks or do they add function?
Both. The purple anodized finish dresses up your lower, but the pin heads have an improved grip surface and pull strength, and the tips run about .030 inch longer than mil-spec to make pushing the pins out easier from the left side. The cone-shaped tip recesses also help keep your punch from slipping and scratching the receiver.
Will these pins interfere with an ambidextrous safety selector?
No. The Enhanced Takedown Pin head is shaped specifically so it does not obstruct a right-side ambidextrous safety selector lever. That makes this a solid match for builds running an ambi safety.
