Strike Industries LINK attachment system takes the age old question Key-Mod vs. M-Lok and came up with the ultimate solution, a dual interface design compatible with both M-Lok and Key-Mod, same hardware with no need for additional parts. This Aluminum rail section allows the attachment of various M1913 Picatinny spec rail-mounted accessories such as vertical grips, lights, lasers, etc. The Dual interface rail section also features beveled ends to reduce snagging and eliminate sharp corners and edges.
