This model will fit the DPMS platform, but when ordering you must add to the notes on the transaction that it is for a DPMS and send drop us an email saying you bought it for a DPMS platform (the threads are different between the two guns)
Notice to owners of DPMS 308 guns: The new uppers on your guns is about .060” lower from centerline of barrel than earlier models. The E1 or earlier rail systems will not mate up or align to the top of your upper receiver. Please be aware of this before ordering a rail system.
Our hand guard rails are machined to the high side of tolerance and there are some items that it will not fit.
Our rails are not suitable for .936 diameter barrels due to the small inside diameter.
