White Label Armory AR15 End Plate 5 Pack, Mil-Spec Phosphate

Description

The end plate is one of those small parts that flies under the radar until you're mid-build and realize how much it's doing. Sitting between the castle nut and the rear of your lower receiver, it captures the takedown pin detent and spring, keeps your buffer tube clocked straight, and adds a layer of protection to the back of the receiver. White Label Armory's version is cut to Mil-Spec dimensions and fits all standard AR15 and AR10 receivers, so there's no guessing whether it'll seat right on your platform.

Getting five in a pack is the real draw here. If you build regularly, keep a couple spare lowers around, or just want backups in the parts bin for the day a detent decides to launch across the garage, having a handful on hand beats ordering one at a time. They're phosphate coated for durability and corrosion resistance, and they're made in the USA to the same standards White Label Armory holds across their parts line.

Where the White Label Armory End Plate Fits in Your Build

When you tighten the castle nut down, it presses this plate flush against the receiver, creating the clamping force that keeps your buffer tube from backing out under recoil. That tight fit matters because a wandering buffer tube can throw off bolt carrier alignment and lead to sloppy cycling. Minimal rotational play means your tube and stock stay clocked where you set them, which makes assembly cleaner and the finished rifle more reliable.

Staking the White Label Armory End Plate

One thing plenty of builders like about a solid phosphate plate is how well it takes a stake. Once you've torqued the castle nut, a center punch displaces a bit of metal from the end plate into the notches on the nut, locking everything in place so vibration can't work it loose over time. It's a minute of work that pays off on rifles that see a lot of rounds. These plates are built to handle that job without complaint.
