TopStop AR Upper Receiver Cover

5 Stars
Ships in 1-3 business days

Product Description

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.

  1. Works great! 5 Star Review

    Posted by on 8th May 2017

    Excellent product, nice tight fit. Does exactly what it says. I like to transport my ARs broken down in a smaller case. The TOPSTOP seals up the upper keeping the inside of my bag clean and debris out of the upper. It will also keep the BCG secure in the receiver. I drilled a hole in the back tab of the TOPSTOP and added a small paracord lanyard. It makes it a little easier to remove it from the upper with one hand while holding the upper in the other hand. I bought one for each of my uppers and I'll buy more for any new uppers I build.

  2. Top Stop AR Upper-Receiver Cover 5 Star Review

    Posted by on 28th Apr 2017

    A must have if you are carrying an AR split between upper and lower. The Top Stop locks the bolt and charging handle in place, keeps lube inside the weapon, and ensures the case stays clean.

    Fit is perfect, and matches both my Daniel Defense and LWRC uppers without fail.

  3. Great fit, and great value for the money. 5 Star Review

    Excellent-designed product to keep dust out of the upper. The fit is very tight. Nice job with this product!

  4. As Advertised 5 Star Review

    Posted by on 8th Apr 2017

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

  5. click done 5 Star Review

    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.

  6. very tight fit excellent 5 Star Review

    Posted by on 18th Feb 2017

    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.

  7. Great Idea! 4 Star Review

    Posted by on 17th Feb 2017

    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?

  8. great product 5 Star Review

    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 !

  9. Just what I needed. 5 Star Review

    Posted by on 11th Feb 2017

    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.

  10. Just what I was looking for ! 5 Star Review

    Posted by on 11th Feb 2017

    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.
