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. Perfect fit 5 Star Review

    Posted by on 10th Jul 2017

    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...


  2. 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.


  3. 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.


  4. 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.


  5. 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.


  6. 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.


  7. 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.


  8. 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.


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

    Posted by on 16th Apr 2017

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


  10. 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.
