TacFire Armorer s Combo Wrench Features The TacFire Armorer s Combo Wrench is designed to service both the 5.56 AR-15 and .308 AR-10 platforms with one tool eliminating the need to keep separate wrenches on hand for each caliber of build. It includes cutouts for .223/5.56 and .308 barrel nuts as well as dedicated free float barrel nut profiles for both platforms covering the most common nut patterns encountered during a build or barrel swap. A 3/4 inch muzzle brake cutout allows the wrench to torque or remove muzzle devices without a separate tool and barrel extension cutouts for both calibers make bolt and barrel service straightforward. A dedicated castle nut wrench profile and an AR-15 delta ring assembly removal tool round out the coverage for stock and handguard work. Beyond barrel and muzzle service the wrench includes 1/4 inch and 7/16 inch hex cutouts along with 1/4 inch and 1/2 inch driver interfaces giving it added versatility for general fasteners encountered during a build. Constructed from steel with a black oxide finish the tool is built to resist corrosion and wear from repeated shop use over time. Its all-in-one design consolidates several single-purpose armorer tools into one compact wrench saving both money and tool box space. For anyone who regularly builds or services AR-15 and AR-10 rifles this combo wrench is a genuinely useful addition to the workbench.
