The Good Stuff

by Hydro, Verified Owner from MO, United States Written on October 3, 2025
This is my second Geissele MK4 rail, first new one. I thought I would save the money and get a cheaper handguard. It just wasn't the same as the Geissele. The MK4 is just better in feel and fit for me. I do wish it would come in a 12 inch version, as the 13.5 was too long for the oversized gas block that came with the barrel. Thanks Geissele, and Optics Planet for the great deal.

geissele handguard

by jay, Verified Owner from PA, United States Written on December 26, 2024
This geissele product comes highly recommended. If your not familiar with geissele, their products are rock solid and this handguard is no exception. Be sure to pick up a geissele barrel nut wrench. And this handguard install is a breeze. The price is as good or better than geissele sells their blem products for , and believe me this has no blems , it is super nice!
