RAVEN CONCEALMENT SYSTEMS TopStop Polymer AR15/M4 Upper Receiver Cover

The TopStop cover is engineered to snap onto most AR15 or M4 type upper receivers when they are detached from the lower receiver. It completely seals the upper receiver, preventing fouling, dust, and sand from getting in or out, and stops the bolt carrier group and charging handle from sliding out while the upper is moved. Made from super tough polymer that is impervious to most solvents and chemicals, it supports safe storage and transport of spare upper receivers. Ideal for low-profile carry, it excels when the rifle must be broken down to fit into low-profile bags.

• Tactical Design: Orange color for a sleek and professional appearance.
• Convenient for Storage: Ideal for storing or transporting spare upper receivers in low-profile bags.
• Durable Material: Made from super-tough polymer, resistant to most solvents and chemicals.
• Bolt Carrier Group Protection: Keeps the bolt carrier group and charging handle securely in place.
• Seals Upper Receiver: Prevents dust and sand from entering or exiting the receiver.
