Not for Holosun, but works in a pinch

by -

I somehow lost the original Holosun cap/cover for my red dot. These are a bit larger in diameter, but work nevertheless. The price was very reasonable too, so I bought two of them!


by -

Fits perfect on my SLX MD25 which I really enjoy.

Outstanding design!

by -

These fit perfectly. Bought 4 but only have 2 SLx-25's. Guess I'll be buying another one sooner than later.

It really works!

by -

Works great to keep the dust out of the red dot and it fits with the ARD installed too.

Great protection

by -

I have several MD25 red dot sights... they are great.... wish they came with covers or this...great to keep the lenses dust free and clean/protected.

Fits Great, But

by -

Fits great. Wasn't sure of the quality so I bought two just in case one would fail. They feel well made and the price is right.
BUT, one should have been included with the purchase of the MD-25.
My MD-20 came with a Bikini cover.
The 4 star rating is for PM not including it with the MD-25.

Should have been included

by -

Excellent bikini cover should have been included with the red dot scope. Did not realize it was not included until I received my red dot scope then had to turn around and order the bikini cover more shipping cost doesn’t make a whole Lotta sense now does it.

PA Bikini Cover

by -

Purchased the sight and added the bikini cover for added protection to the sight. Should come standard with the sight, but it is totally worth it.

Perfect fit but...

by -

Perfect fit and excellent quality. I was surprised and a little disappointed it was not included with the SLX MD-25. Cost me an additional shipping charge.

Nice addition if you use your firearm

Well fitting cover which will serve an important purpose.
