Most Helpful Positive Review Great solution for your upper
Perfect solution for that spare upper you have sitting there. I have a few of these from different companies and this one is the best. I like that there are no pins you have to insert. It snaps in and out with ease but it’s also secure enough to hold the bolt carrier and charging handle.

Works Well

by StevenP, Verified Owner from TX, United States Written on April 30, 2025
I'm generally happy with product function as it provides a snug and secure fit on my POF-USA, PWS, and BRO upper receivers to keep the BCG and charging handle from sliding out during transport or storage (previously, I had been using some thick rubber bands to hold the BCG in place). I think it's overpriced for a piece of plastic though, but there's not really any comparable options available unless you have a 3D printer to make your own.

Does what it says, but I have some thoughts.

by Terry5008, Verified Owner from GA, United States Written on December 16, 2021
I like this product. If you have a lower that you use with a couple of different uppers, it's nice to keep the dust out of the uppers that you aren't currently using. One of my gripes is that the covers are a little too tight, so it takes some effort to remove one. Also, it would be nice to have a BottomStop for lowers that might be stored unattached to an upper. It would also be nice to have TopStops and BottomStops for the DPMS Gen 1 308 pattern.
Pros:
  • Relatively Cheap
  • Works nicely
Cons:
  • Incomplete product line
Would recommend: Yes

These are fantastic

by Tony V, Verified Owner from AZ, United States Written on May 10, 2021
I've got 11 or 12 uppers and five lowers. In addition to storage and display, I often transport my ARs broken down in shorter cases. I've got about a half dozen of these covers. These covers are the best things out there for keeping gunk and grime out of the upper and stay snugly in place to prevent the BCG from sliding out the back and falling into the dirt or tumbling out and falling onto the concrete floor. They snap into place on all of my various forged and billet models and are removed easily without tools or pins, just a nice snug fit. I just wish they made covers for lowers and would make them available in other bright colors besides orange (I like the high visibility of "remove before flight" type components) to mix it up a little bit.
Pros:
  • durable
  • Cheap
  • well made
  • snug fit
  • Hi quality
Cons:
  • Need More Bright Colors
Best Used for:
  • Transportation
  • Storage
  • display
