Wheeler Delta Series XL F.A.T. Wrench Set with Crowfoot Wrenches - Black Steel

The Wheeler Delta Series XL F.A.T. Wrench Set is a professional-grade gunsmithing torque system purpose-built for assembling and maintaining AR-15 and LR-308 platforms. The set pairs Wheeler's XL F.A.T. (Firearm Accurizing Torque) Wrench with five multi-function crowfoot wrenches, giving the home builder or armorer a complete solution for properly torquing castle nuts, barrel nuts, receiver extensions, and other high-stress fasteners on modern sporting rifles.

At the heart of the kit is a 1/2" drive ratcheting torque wrench with an adjustable range of 10-150 ft-lbs (120-1800 in-lbs), delivering more than enough output for every step of an AR-15 or LR-308 build. The adjustable wrench gives the user repeatable torque indication so every critical fastener is brought up to spec without under- or over-tightening, helping protect threads, finish, and accuracy-critical components during assembly and routine maintenance.

The five included multi-function crowfoot wrenches are the standout feature of this Delta Series kit, with each head performing 12 different tasks around the receiver, castle nut, buffer tube, and barrel nut. This dramatically reduces the number of specialty tools required on the bench and makes the set a true all-in-one solution for stock installation, free-float handguard work, and muzzle device fitment. The crowfoots are sized specifically for the fasteners found on mil-spec and commercial AR-pattern rifles.

Construction is hardened black steel finished in the signature Delta Series look, with the torque wrench engineered for the rigors of repeated armorer use. The set ships in a dedicated carry case that keeps the wrench and all five crowfoot attachments organized and protected on the bench, in the range bag, or in transit to a class.

Whether you are building a rifle from a stripped upper and lower, installing a new barrel nut, swapping a free-float handguard, or simply keeping an existing platform properly torqued, the Wheeler Delta Series XL F.A.T. Wrench Set brings the precision and repeatability of a professional armorer to your workbench.
