AR-15 / LR-308 – XL F.A.T. Wrench Set – 10–150 ft-lb – 5 Crowfoot Wrenches
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The Wheeler Delta Series XL F.A.T. Wrench Set is a heavy-duty torque setup built for AR-15 and LR-308 assembly, maintenance, and parts installation where proper torque actually matters. Wheeler designed this kit around a high-torque ratcheting 1/2 inch drive wrench and a complete crowfoot set so you can handle common barrel nut and armorer tasks with more precision and less guesswork.
Fitment
Built for AR-15 and LR-308 bench work, including mil-spec and aftermarket component installation where crowfoot torque applications are needed.
Does NOT fit
Not a universal fix-everything wrench kit for every firearm platform. Verify your barrel nut and armorer task match the included crowfoot profiles before you buy.
What it does
This set gives you controlled torque from 10 to 150 ft-lbs. for higher-torque AR work, paired with five dual-ended crowfoot wrenches that cover multiple armorer functions. It is meant for builders and gunsmiths who need repeatable torque instead of “that feels about right” and a prayer.
Why it’s worth it
If you build or service AR-platform rifles often, this makes a lot more sense than piecing together random torque tools that may or may not fit the job. The included crowfoot set gives this kit real utility, and the higher torque range makes it useful for serious assembly work instead of just light-duty bench tasks.

Install notes
Use the correct crowfoot for the specific barrel nut or armorer function, follow manufacturer torque specs, and account for crowfoot orientation when applying torque. This is a precision tool, not a license to muscle through bad setup.
