This is sold with RMP Backer Plates™ for easy installation without a nut or bolt protruding through the back of the RMP™. Just The Clamp variant now includes a nut, bolt, and washer, to mount the clamp through an existing hole, slot, or a drilled hole.
QuickFist® Go-Between Clamp - Enlarged [Handguard] is versatile and it also suits perfectly with my shotgun. I've paired it with a buttstock cup on a 15.25 X 25 RMP on my Jeep and it's perfect for patrol, hunting or a day at the firing range.
