Our Take
257 mm of rail and 25 slots, in aluminum alloy at about 130 g. That is a lot of mounting real estate for the weight, which makes it a candidate for spreading a long scope across two rings or staging a light plus a grip on one handguard. The 20 mm width matches Picatinny and Weaver gear. One honest caution: long bases amplify any height mismatch with your receiver, so check how flat it sits before torquing everything down. If you need one uninterrupted run of rail, this covers it.
