The Raven Concealment Systems Top Stop upper receiver cover is a practical protective accessory for AR15 and M4 platform rifles. When you're running a detached upper—whether you're swapping barrels at the range, transporting your rifle, or building a new configuration—this snap-on cover seals and secures your upper receiver in a few seconds. It's the kind of small detail that keeps dust, dirt, and debris out of critical components while preventing the bolt carrier group and charging handle from sliding freely as you move the upper around.
Built from tough polymer, the Top Stop is designed to fit most standard AR15 and M4 pattern uppers when they're off the lower receiver. The cover snaps in place without tools and provides a straightforward way to protect your investment during storage, transport, or between-configuration changes. It's not flashy, but it solves a real problem: a naked upper sitting on a workbench or in a bag collects grit and invites contamination. This keeps that from happening.
Raven Concealment Systems built their reputation on no-nonsense gear that works in the field and at home. The Top Stop fits that philosophy—it's not essential to function, but once you use it, you'll understand why it's become standard equipment for serious shooters who take care of their hardware.
| Brand | Raven Concealment Systems |
| Product Type | Upper Receiver Cover |
| Compatibility | AR15 and M4 type upper receivers (detached) |
| Material | Polymer |
| Color | Black |
The Top Stop is designed to snap on most AR15 and M4 pattern upper receivers. It only works when the upper is detached from the lower receiver. If your upper follows standard mil-spec dimensions, it should fit; if you have an unusual or proprietary upper, fit may vary.
No. The Top Stop snaps on without tools or disassembly. It's designed to work with your upper as-is when it's off the lower.
The Top Stop seals the open top of your detached upper receiver, keeping dust, dirt, and debris out of the bolt carrier group, barrel extension, and internal surfaces. It also prevents the charging handle and bolt carrier from moving around when you're transporting or handling the upper.
No. The Top Stop is designed only for detached uppers.
