Building an AR-15 lower comes down to a fistful of small parts, and losing track of one springy detent can bring the whole project to a halt. Rise Armament put together this kit to cover the bases without forcing a trigger on you. It's a 20-piece, mil-spec set with all the working components of a lower receiver except the fire control group, pistol grip, and trigger guard. That means you get the pins, springs, detents, catches, and safety selector, then drop in whatever trigger fits how you like your rifle to break.
Inside you'll find the pivot and takedown pins with their matching springs and detents, the magazine catch assembly with spring and release button, the bolt catch with its plunger, spring, and roll pin, a standard safety selector with detent and spring, the buffer retainer and spring, and a pair of standard trigger and hammer pins. It's the full spread of hardware that usually goes walking across the bench when you least expect it. Keeping a spare kit on the shelf is a smart move for anyone who wrenches on ARs regularly.
Most of the parts are made from industry-standard 8620 steel, an alloy of nickel, chromium, and molybdenum that machines clean and stands up to hard use. The safety detent pin and the takedown and pivot pin detents are made from yellow zinc for extra wear resistance. Many of the components wear a black phosphate finish, which lays down a protective layer to fight off corrosion through long stretches of shooting.
This kit is compatible with mil-spec AR-15 lowers, so it plays nice with the vast majority of stripped receivers on the market. Rise builds its parts under AS9100 and ISO9001-certified procedures with quality checks before anything ships, and the kit is backed by a lifetime warranty. Whether you're starting a fresh build or refreshing an older lower, this set gives you a dependable foundation to work from.
No. This is the minus-trigger version, so it leaves out the fire control group entirely. It does include the two standard trigger and hammer pins, so once you drop in your chosen trigger you're ready to pin it in place. You'll also need to supply your own pistol grip and trigger guard.
It's built to mil-spec dimensions, so it's compatible with the wide majority of mil-spec AR-15 stripped lowers on the market. If your receiver is a proprietary or non-standard design, it's worth double-checking the spec before ordering. For standard builds, it drops right in.
Most components use industry-standard 8620 steel, an alloy of nickel, chromium, and molybdenum that's tough and wear resistant. The safety detent pin and the takedown and pivot pin detents are made from yellow zinc. Many of the parts also carry a black phosphate finish to help fight corrosion over long stretches of shooting.
Absolutely. Springs, detents, and roll pins are notorious for pinging off the bench and disappearing during a build. Keeping a full 20-piece kit on hand means a single lost part won't stall your project, and it's cheap insurance for anyone who works on ARs regularly.
