Daniel Defense Bolt-up RIS-II barrel nut wrench - heavy duty

Heavy Duty version of the legacy DD RIS wrench

The Bolt-Up System Barrel Nut Wrench is a proprietary spanner wrench required to install our Bolt Up System Barrel Nut. This wrench is designed to be used with a 1⁄2 Drive Torque Wrench

The heavy duty RIS wrench is made to last for over 100 barrel nut tightenings and loosening. If you have used the regular RIS wrench, and it bent, you will appreciate this wrench. It is much thicker and meant to last. This is a Daniel Defense product, and unfortunately has the same SKU as the older aluminum wrenches, but Charlie's has segregated the sloppy aluminum wrenches from the more heavy duty steel wrench. Many will not have DD logos, but these are made by Daniel Defense.

DD recommends using a torque wrench and applying 55 ft-lbs of pressure. If you are loosening and have trouble, you may need to work on the barrel nut with heat or a solvent first. Take care not to injure your receiver with too much torque.

The Bolt Up System Barrel Nut Wrench is used on the following rails:

MFR XL

MFR Rail

SLiM Rail

DDM4 Rail

AR15 Lite Rail

AR15 Lite Rail II

AR15 Lite Rail III

Rail Interface System II (RISII)

Note on use: Like the aluminum wrench, this steel wrench can still be bent. IF YOU USE IT THE WRONG WAY, IT WILL OPEN UP ON YOU. We like to tell our customers: "Close the C." You must pull the wrench with you to put pressure on the wrench to close-up on the barrel nut. If you push the wrench, you will open the wrench up, and then it will be bent, and last tine will not fit. It is what it is. It works well, if you follow these instructions. If you don't, you might have to hammer the wrench back into shape.
