Building out an AR-15 lower and need the receiver extension squared away? The One Horse Carbine Buffer Tube Kit handles that whole job in one box. It's a six-position Mil-Spec setup, so it accepts any standard Mil-Spec collapsible stock and lets you dial in your length of pull whether you're shooting from a bench, working close-in, or just trying to fit the rifle to different folks at the range.
The tube itself is CNC-machined from 7075-T6 aluminum and finished with hardcoat anodizing, which is the same recipe you'll find on quality receiver extensions across the board. That combination shrugs off wear and holds up to the constant pounding the buffer system takes every time the rifle cycles. The 1.148-inch Mil-Spec outer diameter means your stock slides on snug without the wobble that plagues commercial-spec tubes mismatched to the wrong stock.
This isn't just a bare tube. You get the carbine buffer, the Mil-Spec recoil spring, the receiver end plate, and the castle nut, so there's no hunting around for the small parts that always seem to get left out of cheaper kits. The end plate keeps your rear takedown pin detent and spring captured, and the castle nut locks the whole assembly down against the receiver.
It's a natural fit for a first-time builder finishing a stripped lower, or anyone refreshing a tired buffer system on an older rifle. One Horse builds its parts in America with U.S.-sourced materials and tight quality control, so you're getting dependable, no-surprises hardware at a working-man's price rather than a boutique markup.
Pair it with any Mil-Spec carbine stock and an armorer's wrench, torque the castle nut down, and you've got a clean, adjustable rear end on your AR ready for range day.
You get the six-position Mil-Spec carbine buffer tube, the carbine buffer, the Mil-Spec recoil spring, the receiver end plate, and the castle nut. That's the complete back-end hardware needed to mount a collapsible stock to your AR-15 lower. The only extra you'd want on hand is a stock and an armorer's wrench for installation.
Yes, this is a Mil-Spec tube with the standard 1.148-inch outer diameter, so it fits any Mil-Spec carbine collapsible stock. Just make sure your stock is Mil-Spec and not commercial-spec, since those are slightly larger and won't pair correctly. Mixing the two is the usual cause of a wobbly stock.
It's Mil-Spec, machined from 7075-T6 aluminum and hardcoat anodized. Mil-Spec tubes are generally considered the stronger and more widely supported option since the diameter is forged and most aftermarket stocks are built around it. If you're building or upgrading, Mil-Spec is the safer bet for parts compatibility down the road.
Staking isn't strictly required, but it's a smart habit on any rifle you plan to shoot regularly. Torquing the castle nut to spec and staking it keeps the end plate and tube from backing off under recoil and vibration, which can eventually let your takedown pin detent and spring fall out. For a range or hunting gun that sees lighter use, a properly torqued nut with a witness mark is often enough.
An armorer's wrench is the main thing, used to tighten the castle nut down onto the buffer tube against the end plate. If you want to stake the castle nut, you'll also want a center punch and a small hammer, or a spring-loaded punch. A vise and lower receiver block make the whole job a lot easier and steadier.
Yes, One Horse builds its components in America using U.S.-sourced materials with quality control at each step. That's part of the appeal here, you're getting domestically made hardware without the boutique price tag. It's straightforward, dependable gear meant for everyday use.
