GG&G, Inc. Mossberg 590 Sling And Flashlight Mount Specifications: Installs easily. Designed and manufactured to withstand the rigors associated with professional use. When used by a right handed shooter the accessory rail will point rearward.
This is a simple yet beyond effective product. It adds a sling point at the front, and a small section of rail that I plan on using for a flashlight. It is reversible left and right. I would not recommend this for a laser. There is some play that will not allow a laser to hold a zero. The finish looks really well, almost matches my 590a1 finish. The embedded defend ball works great, it mimics the one that came on the 590a1. Solid construction. Well made. I can't guage the hardness, but it's not bending without adding some heat. Well worth the price.
Great quality, fits the shockwave as well. Is a little loose not so loose that it’s annoying or that the barrel is shifting forward just very minor play on the rail, realistically not much need for a laser on a shotgun anyway but perfect for a flashlight. It’s your Standard glock 17/19 Rail so if u have a flashlight for that kind of pistol then it will fit.
