TopStop AR Upper Receiver Cover

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 as advertised 5 Star Review

    Posted by on 25th Aug 2017

    Although the fit is very tight at the locking nubs that hold the cover on, I expect it will become easier to put on and remove the more it's used. The molding to match the shape of the upper receiver openings is accurate and fits perfectly. The material is quite hard and I expect it will work as advertised for a long time.

  2. Fills the need 5 Star Review

    Posted by on 18th Aug 2017

    I have a handful of AR uppers, more than i do lowers, and reciever covers work well keeping the BCGs in place. Either in storage case or in one of my small weapon case, or in my discrete carry bag (rifle has to be seperated to stow in the case). Also makes it easy to carry a second upper when i feel like it.

  5. Perfect fit 5 Star Review

    I only have used two of these covers so far but am very impressed at the fit and bolt containment. I'm glad I found them. Now all I need is a lower cover...

  6. nice fit 5 Star Review

    Posted by on 19th Jun 2017

    Nice tight fit, almost to tight. But not complaining because it will probably get looser with time and wear. And it is better for it to be tight now and not to loose later.
    I would love a lower receiver version to keep dust and lint out of the trigger group.

  7. What a great idea! 5 Star Review

    Posted by on 18th Jun 2017

    I purchased three of these quality, glad somebody thought of this, products.
    The figment in my uppers is tight and secure. No more worries about bolt sliding out when traveling with uppers & lowers separated.

  8. Almost fits Colt 4 Star Review

    Posted by on 16th Jun 2017

    I bought this for my Colt AR15 A2 and it almost fits. Unfortunately there is a small protrusion that is made to fit into the bottom of the upper receiver to help seal it. However it is larger than the cutout in original Colt ARs. Kind of the standard. It will hold the bolt in and provide some protection, but a little planning and they could have easily made it fit everything.

  9. exactly as advertised 5 Star Review

    Posted by on 1st Jun 2017

    This product fits snugly and is exactly as advertised. Great for storing additional upper relievers in the range bag. Also makes a great mask for cerakoting uppers.

  10. exactly what I needed 5 Star Review

    Posted by on 14th May 2017

    This will seal your upper receiver so you can store it in two pieces. Keeps the big in place and contains any oil so it doesn't mess up your case.
