Made in the usa, the ms1 ms3 qd adapter features a manganese-phosphate finish push-button qd sling swivel for one-point attachment, and can be combined with the ms1 sling (mag513) and additional paraclip (mag541) to provide fast transition between one-point and two-point configuration.It also has a custom 1.25" wide nylon webbing material, and colored webbing has near infrared (nir) treatment to reduce ir signature.For rear attachment it works with receivers, end plates, and buttstocks that have a push-button qd socket for one-point attachment.Snap-hook style sling loops with an inner diameter of at least 3/8" are required, but 9/16" and larger will provide full range of motion of the paraclip.Color: Ranger GreenMaterial: Steel
