These are meant to be used with the manticore arms transformer handguard. The handguard is configurable to swap out sections with either panels or mlok / keymod slots. This is why it doesn't come with any hardware. You are supposed to use the existing hardware that is supplied when you buy the handguard. You can use them with any other handgurds, but you have to purchase the hardware yourself.

1st off, it's hard to find reasonably priced large frame, G20 / G21 suppressor height sights. These are not large frame sights. In fact, they are dimensionally identical to the small frame ones. I re-checked the packaging, thinking maybe they mixed them up in shipping, and that was not the case. The packaging said ABA152, which is supposed to be the large frame ones. I put these up on a Glock 21 slide, and they dont even fill up half of the slide. They look like baby sights. These will work on a 17 or 19 slide, but thats not what i needed.

Also, i bought these in June 2024, and Optics Planet said shipping estimate 7 to 14 days. I did not receive these until 6 months later, in November. They had the small frame ones in stock, but i needed large frame sights, so i waited 6 months to receive the small frame sights branded as large frame ones.

These are junk. They don't fit milspec or billet uppers.. The covers will not close or latch. Tried on 3 uppers. None of them worked.. Stick with the Strike industries ones, These are very disappointing
