RAVEN TOP STOP URG COVER YELLOW$19.99
Availability: In Stock
The Raven Concealment Systems TopStop URG Cover in orange is a no-nonsense protective cap designed for AR-15 and M4 platform upper receivers when they're separated from the lower. If you're running a modular rifle setup, swapping uppers between builds, or just need to keep a spare upper clean and protected during transport or storage, this snap-on cover seals the receiver opening and prevents dust, debris, and fouling from contaminating your bolt carrier group or charging handle during handling.
Built from durable polymer, the TopStop cover snaps securely onto your upper receiver and does double duty: it physically prevents the bolt carrier group and charging handle from sliding out as you move the upper around, and it seals the receiver against environmental contamination. That's especially valuable if you're prepping a backup upper, taking guns to the range, or managing multiple uppers in the field. The bright orange finish makes it easy to spot and identify protected uppers at a glance.
This is a straightforward, practical accessory for anyone who shoots modular AR platforms and wants to protect their investment between use. It works on standard AR-15 and M4 type uppers—just remember it only fits when the upper is detached from the lower receiver.

| Product Name | TopStop URG Cover |
| Color | Orange |
| Material | Polymer |
| Fitment | AR-15 and M4 type upper receivers (detached) |
The TopStop is designed to snap on most AR-15 and M4 type upper receivers. It works on standard uppers when they are detached from the lower receiver. If you're unsure about compatibility with a proprietary or non-standard upper, contact us with your upper's specs.
No. The TopStop cover only fits when the upper receiver is separated from the lower receiver. Once the upper and lower are mated, the cover will not snap on properly.
The cover seals the upper receiver opening to prevent fouling, dust, and debris from getting inside or out. It also physically prevents the bolt carrier group and charging handle from sliding out when you're moving or handling the detached upper.
The bright orange finish makes it easy to quickly identify which uppers are protected at a glance, especially useful if you're managing multiple uppers or storing them in a safe.
