XM4SD Carbine Aluminum Quad Rail is designed to exceed the requirements of the US Army for improving zero retention and repeatability. With a slimmer profile, this Picatinny quad rail improves durability, reliability and maintainability while interfacing with all issued weapon system components. The XM4SD has four full length rails and the top rail, with the existing flat top rail, creates one long monolithic rail. It has four push button sling mounting points at the front and back, and slots around the rails to provide maximum ventilation. CNC-machined from aviation grade aluminum to MIL-1913 standards, the XM4SD has a hard anodized black oxide finish for durability and ease of maintenance.XM4SD Carbine Aluminum Quad Rail requires delta ring removal.

Oregon residents: If you are making a firearm purchase online from us, please understand, you are more than likely going to go in the FICS background check line of over 37,000. This means, that there's a good chance you'll still be in line on the 18th of December and are at the mercy of what the Judge in Harney County decides. At the point, there's a chance you'll have to get a permit-to-purchase said firearm. There will be no refunds for people that go in line and have to wait. Purchase at your own risk. That being said, we will continue to fulfil orders as they come in. Thank you for your patience! ~ Fifty1Fifty Tactical, LLC
