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. 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.


  2. 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.


  3. exactly what I needed 5 Star Review

    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.


  4. 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.


  5. 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.


  6. 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!


  7. 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.


  8. click done 5 Star Review

    Posted by on 26th Mar 2017

    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.


  9. 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.


  10. 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?
