Battle Arms Development AR15/M16/M4 Quick Release Rear Takedown Pin | Steel

The Battle Arms Development AR15/M16/M4 Quick Release Rear Takedown Pin in steel is an enhanced takedown pin engineered to speed up rifle manipulation and simplify upper receiver separation. This Battle Arms Development AR15/M16/M4 pin is precision CNC machined from steel and built to true mil-spec .250 inch dimensions, so it drops in where your standard rear takedown pin lives. Its dual-function design is purpose-built for shooters running feature-restricted, fixed-magazine, or rapid-access AR configurations. Where a standard pin only holds the receivers together, this one actively makes reloads and maintenance faster.

Opening the action quickly matters more than most shooters think, whether you are clearing a stubborn malfunction or reloading a fixed-magazine build. A slow, fiddly pin costs you time exactly when you cannot spare it.

What the Battle Arms Development AR15/M16/M4 Quick Release Pin Is and Who It Is For

This is a quick-release rear takedown pin that lets you pop the upper open faster than a standard captured pin allows. It is aimed at shooters who need rapid access to the action, especially those running fixed-magazine or feature-restricted builds where reloading means opening the receiver.

Owners of compliant, fixed-magazine rifles constantly search for enhanced takedown pins because standard pins are slow and fiddly under stress, particularly with gloves. This pin is built to make that process quick, repeatable, and reliable. It turns a chore into a smooth, practiced motion.

Key Features

Key features of this quick release rear takedown pin include:

• Precision CNC machined from steel for rugged, long-lasting durability
• True mil-spec .250 inch dimensions for a correct, drop-in fit
• Innovative dual-function operation for quick upper receiver separation
• Ideal for feature-restricted, fixed-magazine, and rapid-access AR builds
• Improves handling speed during reloads and routine maintenance
• Direct upgrade over slow, hard-to-manipulate standard takedown pins

Specs and Build Quality

Machined from steel, the Battle Arms Development AR15/M16/M4 pin brings rugged durability to a part that gets pushed, pulled, and pivoted constantly. Building it to true mil-spec .250 inch dimensions means it fits standard AR-15, M16, and M4 lowers without any fitting, so you get the speed benefit with zero compatibility guesswork.

The dual-function operation is the real upgrade, letting you separate the receivers quickly instead of fighting a standard captured pin. For a rifle that opens often, whether for a fixed-magazine reload or a fast cleaning, that speed adds up fast. Steel construction ensures the pin holds up to that repeated cycling without wear or slop.

Practical Use, Care, and Compatibility

On a fixed-magazine build, the quick-release pin turns a slow reload into a smooth, practiced motion. On any rifle, it makes field stripping and maintenance quicker, which means you are more likely to keep the gun clean and running right.

Keep the pin and its detent clean for smooth operation and confirm function after installation. It fits standard .250 inch AR receivers and pairs well with the other build components in our AR-15 parts and upgrades. Made by Battle Arms Development, this pin brings speed and simplicity to a part most shooters never think to upgrade.

Installation and Field Notes

The pin drops into the standard rear takedown location and installs with the factory detent and spring. Take a moment to learn its dual-function operation on the bench so the motion is second nature before you need it under time or stress.

On a fixed-magazine rifle, popping the upper to reload becomes a smooth, repeatable move rather than a fumble. On any rifle, faster receiver access means quicker cleaning and inspection, which tends to translate into a gun that gets maintained more often. Keep the pin and detent free of grit and it will open and close cleanly for years.

Open your action faster with the Battle Arms Development AR15/M16/M4 Quick Release Rear Takedown Pin in steel. It is a small change that speeds up everything you do with the upper. Ships direct to your door, no FFL required.
