The TopStop cover is designed to snap on most AR15 or M4 type upper receivers when they are detached from the lower receiver. The TopStop completely seals the upper receiver preventing fouling from getting in or out and it stops the bolt carrier group and charging handle from sliding out as the upper is moved around. The TopStop is made out of super tough polymer and is impervious to most solvents and chemicals. This product is perfect for storing or transporting your spare upper recievers, especially in low-profile bags where the rifle must be broken down to fit.

Initially concerns with fit were unfounded. Fit is snug and requires some effort to remove. Does what it needs to do.

Awesome little device! I keep a short upper in a bag with an SPR. Nice that this snaps on and keeps bolt carrier group tightly in the upper. Surprised these things aren't more prevalent in shops.

I ordered a dozen Top Stops and received them witihin 3 weeks in the Netherlands (europe).
A very tight fit on the upper but they work fine.
Second order is coming.

For a while, I was looking for a product like this; that I could put on my uppers and keep my range bag clean and all the upper bits inside where they belong.
What else can I say? Well, it works as advertised. Negative? It kinda sticks a little too hard to the charging handle side of the upper, no a deal breaker for me.
Also; guys, could you make this cheaper? Or a bundle of 3 for 16.99?

If you have more than one upper receiver , this is a must have product to secure your bolt and charging handle all to your upper. No free play, very well built. Great product !

Because of a lack of storage space, I've taken to storing some of my lower receivers in my safe and the corresponding uppers in soft cases elsewhere. The TopStop cover is perfect for this situation. It snaps in place and keeps your bolt carrier/charging handle from sliding out and it protects the mating surface of your upper receiver. Nice product.

I have been trying to figure out how to break down my AR pistol to fit in my sling bag and not make a mess of everything in the bag and keep the BCG in place. I found the Raven Concealment systems Top Stop on Facebook I thought it was a neat Idea but I was a little skeptical but I figured I would check it out. It was perfect! I ordered 4 and they arrived very quickly. I tried them out on the AR pistol and on some of the uppers on my Rifles. They work like a charm!!! They are a must have for anyone with an AR.

This product is perfect for people that have extra Ar uppers.
Also perfect for breaking down to put in a smaller Ar case for
travel. Holds your Blot carrier and charging handle in place

The TopStop is great! I choose to have a small rifle bag so I disassemble my rifles. The receiver cover holds the bolt securely in and prevents my bag from getting all greasy or dirty. The fitment is snug and tight since it's new, but I'm sure will loosen up with time. Built with RCS quality!!
